Skinboosters vs Rejuran for Men: Bangkok Guide 2026

Walk into almost any aesthetic clinic in Bangkok and you will hear two names that get used as if they were interchangeable: Skinboosters and Rejuran. They are not. Both are injected into the skin with very fine needles, both improve what dermatologists call skin quality, and both leave you looking like a slightly better-rested version of yourself rather than someone who has obviously had work done. But they are built from different materials and they work through different biology. One mainly hydrates. The other mainly repairs.

For men, the distinction matters more than the marketing suggests. Male skin tends to be thicker, oilier and more prone to sun damage and shaving irritation, and a lot of the men we see have never had an injectable in their life and want the least fuss possible. Choosing the right treatment the first time saves money and avoids the frustration of paying for hydration when what you actually needed was repair, or vice versa. This guide breaks down how each one works, what they realistically cost in Bangkok against US and UK prices, who should and should not have them, what recovery looks like, and how to decide, including when running both makes sense.

A quick note before we go further: both Skinboosters and Rejuran are prescription-grade injectable treatments. Nothing here is a substitute for an in-person assessment. A doctor needs to look at your skin, take a history and confirm you are a suitable candidate before anything is injected.

The short version

Skinboosters are microinjections of hyaluronic acid (HA), the same water-binding molecule your skin already contains. Spread in tiny deposits across an area, they pull in moisture, plump fine lines from the inside and give skin a smoother, brighter surface. You usually notice the glow within one to two weeks, and a session tends to hold for around four to six months.

Rejuran is a different category altogether. It is a polynucleotide (PN) gel made from purified, fragmented salmon DNA. Rather than simply holding water, it signals your skin's own repair cells (fibroblasts) to produce fresh collagen and elastin. That makes it the better tool for dullness with a loss of firmness, early lines, sun damage and acne scarring. The trade-off is patience: improvement builds over roughly one to three months across a short course, and results commonly last six to twelve months.

If you remember one thing, remember this. Skinboosters are about hydration and surface quality. Rejuran is about regeneration and structure. The rest of this article is detail.

What Skinboosters actually are

"Skinbooster" is a category, not a single brand. The term covers injectable hyaluronic acid products formulated to be placed in many small, shallow deposits rather than in one bolus the way a cheek or jaw filler would be. Well-known examples used in Bangkok include Restylane Skinboosters (Vital and Vital Light) and Juvederm Volite, among others.

The HA used is either lightly stabilised or non-cross-linked, which is what lets it spread and integrate rather than create volume or shape. Because HA binds many times its own weight in water, the immediate effect is hydration that comes from within the dermis, not from a cream sitting on top of it. Over the following weeks, the better products also appear to nudge fibroblast activity, so part of the benefit is improved skin texture and elasticity rather than moisture alone.

A 2023 systematic review in *Clinical, Cosmetic and Investigational Dermatology* looking at injectable HA for facial skin quality concluded that HA formulations produced significant improvements in hydration, firmness, fatigue, brightness, texture and elasticity, with high patient satisfaction and a good safety profile. The same review was candid about the limitations of the evidence: small studies, few randomised controlled trials and a reliance on subjective scoring. In plain terms, Skinboosters do what they claim for most people, but the science is still maturing and individual results vary.

For men, Skinboosters tend to suit:

• Dull, dehydrated skin that looks tired even after sleep

• Fine lines and crepey texture, especially under the eyes, on the forehead and around the mouth

• Skin roughened by years of sun, shaving and city pollution

• Anyone who wants a fresher look without any change in facial volume or shape

What they will not do is lift sagging skin, fill deep folds or rebuild a weak jawline. That is the job of structural fillers or biostimulators, which we cover in our guide to dermal fillers and in dermal fillers vs biostimulators.

What Rejuran actually is

Rejuran is the best-known polynucleotide injectable on the market. It is manufactured in Korea from the DNA of salmon, which is fragmented into polynucleotide chains and highly purified so that the genetic material is reduced to inert building blocks with no species-specific information left. Sperm and similar germ cells are used as the DNA source precisely because they yield very pure DNA with minimal protein and lipid contamination, which lowers the risk of an immune reaction.

The mechanism is where Rejuran separates itself from a simple hydrator. Polynucleotides and the closely related polydeoxyribonucleotides (PDRN) act as signalling molecules in the skin. A 2025 review in *Biomaterials Research* on PDRN for tissue regeneration describes how these fragments, and the adenosine they release, engage adenosine receptors to drive angiogenesis (new blood supply), dampen inflammation and stimulate collagen production. A 2025 comparison of PN and PDRN in *Pharmaceutics* adds useful nuance: longer-chain polynucleotides like those in Rejuran behave partly as a hydrating, supportive hydrogel, while also helping downregulate the enzyme (MMP-1) that breaks collagen down and encouraging fibroblasts to make more of it. The net effect is skin that is firmer, smoother and better repaired over time rather than simply wetter.

A 2024 review in the *International Journal of Molecular Sciences* on polynucleotides in aesthetic medicine reported improvements in skin texture, wrinkle depth, elasticity and hydration across the published studies, while noting honestly that results were mixed and that larger high-quality trials are still needed. That is a fair summary of where polynucleotides sit in 2026: a regenerative treatment with strong mechanistic logic and encouraging clinical reports, not a guaranteed outcome.

Rejuran tends to suit men with:

• Dull skin combined with early loss of firmness and elasticity

• Sun damage and the general "weathering" that accumulates with age and outdoor life

• Acne scarring and uneven texture (with the scar-specific formulation, more below)

• A preference for natural anti-ageing that adds no volume and changes nothing about facial shape

For a deeper men-specific walk-through, see Rejuran for men in Bangkok and our broader polynucleotides for men explainer.

The Rejuran product family

One reason consultations matter is that Rejuran is not a single product. The line includes several formulations, each tuned to a different concern, and a good injector chooses (or combines) based on your skin rather than defaulting to one box.

Healer is the classic all-rounder. HB blends in hyaluronic acid so it overlaps somewhat with a Skinbooster, which is why it is often suggested for dehydrated or first-time skin. S is the one to ask about if acne scars are your main concern, and is frequently combined with other modalities such as subcision or pico laser for better results. I is reserved for the thin, delicate skin around the eyes.

Skinboosters vs Rejuran: side by side

Two products that often come up in the same conversation are Profhilo and exosomes. Profhilo is a high-concentration HA bio-remodelling injectable that sits conceptually between a Skinbooster and a structural treatment; we compare it directly in Profhilo vs Skinboosters and Rejuran vs Profhilo. If you have specifically been weighing Rejuran against other polynucleotide brands, our polynucleotides vs Rejuran article covers that ground.

Pricing in Bangkok, and how it compares to the US and UK

Bangkok is one of the more competitive markets in the world for injectable skin treatments, which is a large part of why men travel here for them. Prices below are indicative ranges drawn from current Bangkok clinic pricing in 2026 and should be confirmed at consultation, because the final figure depends on the exact product, how many vials or syringes your area needs, and whether you buy a course.

Converted roughly, THB 14,500-25,000 is about USD 400-700 per Rejuran session at mid-2026 exchange rates, and a Skinbooster session of THB 8,000-18,000 is about USD 230-510. Comparable single sessions in major US cities and in London commonly run 40-60% higher once you account for clinic fees, so a man having a full Rejuran course in Bangkok can pay meaningfully less than he would at home, even before factoring in that Bangkok clinics often bundle in extras like ultrasound or a hydrating mask.

A word of realism on cheap quotes. Some Bangkok clinics advertise Rejuran "from" a low per-vial price (around THB 9,000), but a full face often needs two or more vials, so the per-session cost is what you should actually compare. Treat a very low headline price the same way you would anywhere: ask what product, how many vials, and who is injecting.

What drives the cost

• Product and formulation. Genuine, properly stored Korean Rejuran and branded Skinbooster HA cost the clinic more than grey-market or unbranded alternatives. The Rejuran sub-type matters too; the scar formulation and combination products can sit at the higher end.

• Volume needed. A small area such as under-eyes uses far less product than a full face and neck. Larger or more damaged areas cost more.

• Number of sessions. Skinboosters are typically a short initial course then maintenance; Rejuran usually needs three to four sessions to show its full effect. Course pricing lowers the per-session cost.

• Who injects you, and where. A doctor-led clinic with proper sterile facilities and product traceability will rarely be the cheapest, and that is appropriate. Injector skill directly affects both safety and how natural the result looks.

• Add-ons. Numbing, post-care masks, ultrasound and review appointments may be included or charged separately. Ask for an all-in figure.

Who is a good candidate, and who should wait

Most healthy adult men are candidates for one or both of these treatments, but neither is for everyone, and a consultation exists partly to screen for the situations where they are not appropriate.

You are likely a good candidate if you are in general good health, your skin concern is quality-related (dryness, dullness, fine lines, mild laxity, texture or scarring) rather than something that needs surgery, and you have realistic expectations that these are gradual, maintenance-based treatments rather than a one-off fix.

These treatments are usually not the right choice, or need to be deferred, if any of the following apply:

• Active infection, acne flare, cold sore or inflamed skin at the planned injection site. Treat the flare first.

• A known allergy to any component. For Rejuran specifically, raise a true fish or salmon allergy with your doctor; while the DNA is highly purified, this is a conversation to have rather than assume.

• Pregnancy or breastfeeding. These treatments are generally avoided because they have not been studied in this group.

• A history of keloid or hypertrophic scarring, which changes the risk calculation for any needle treatment.

• Bleeding disorders or use of blood thinners, which raises the bruising risk and needs to be managed in advance.

• Autoimmune or immune-modulating conditions, or current immunosuppressive treatment, which warrant individual medical assessment.

• Unrealistic goals, for example expecting an injectable to replace a facelift, lift heavy jowls or fill deep folds. Those need different treatments.

This is not a complete list, and it is exactly why the law and good practice require a face-to-face medical consultation and prescription before treatment. Your doctor may also ask you to pause certain supplements (such as fish oil, vitamin E or high-dose anti-inflammatories) for a few days beforehand to reduce bruising.

The procedure, step by step

The two treatments feel broadly similar in the chair. Here is what a typical session looks like.

1. Consultation and assessment. A doctor reviews your skin, your goals and your medical history, confirms you are suitable, and agrees a plan: which product, which areas, how many sessions.

2. Cleansing and numbing. The area is cleaned, and a topical numbing cream is applied, usually for 20-30 minutes. Some Rejuran formulations also contain lidocaine for added comfort. Most men describe the discomfort as mild once numbed.

3. Injection. Using a very fine needle (or sometimes a cannula), the practitioner places many small deposits across the treatment area. Skinboosters are spread to hydrate evenly; Rejuran is placed to seed repair. A session typically takes around 20-40 minutes depending on the area.

4. Immediate aftercare. A soothing or hydrating mask and gentle cooling are common. You will see small bumps and possibly minor redness right away.

5. Review. Your clinic should tell you when to return, whether for the next session in your course or for a results review.

Because both are delivered as multiple microinjections, the experience is more "many tiny pricks" than one sharp jab, and a numbing cream makes it very manageable for the large majority of patients.

Recovery and the results timeline

Neither treatment requires meaningful downtime. Most men go straight back to work or the gym the same day or the next, which is part of the appeal.

Skinboosters, day by day:

• First 24-48 hours: small raised bumps where the HA was deposited, sometimes slight redness or pinpoint bruising. The bumps settle as the HA integrates and draws in water.

• Days 3-7: swelling and marks resolve; skin starts to feel more hydrated.

• Weeks 1-2: the characteristic glow, smoother texture and softened fine lines become visible. This is when most people feel they got their money's worth.

Rejuran, day by day:

• First 24-72 hours: small injection marks that look like mosquito bites, occasionally with minor bruising. These are normal and usually fade within a few days.

• Weeks 2-4: early improvement in smoothness and tone as the regenerative process gets underway.

• Months 1-3: the real payoff, with firmer, more even and better-repaired skin building across the course of sessions.

General aftercare for both: keep the area clean, avoid heavy makeup, intense heat (sauna, hot yoga), strenuous exercise, alcohol and direct sun for about 24-48 hours, and use sunscreen diligently afterwards. Avoid rubbing or massaging the area unless your clinician tells you otherwise.

What results to expect, realistically

Quantifying aesthetic outcomes is tricky because so much is subjective, but here is an honest framing.

Skinboosters reliably improve measured and self-reported skin hydration and quality for most people, with the systematic review evidence pointing to gains in hydration, brightness, texture and elasticity over a course of treatment. Expect a fresher, smoother, better-hydrated complexion and softer fine lines, typically lasting four to six months before a top-up is worthwhile.

Rejuran's benefits accumulate. Across the published reviews, polynucleotide treatment is associated with improvements in texture, wrinkle depth, elasticity and the appearance of scars, with the caveat that study quality varies and not everyone responds equally. In practice, a course of three to four sessions commonly yields visibly firmer, smoother and more even skin that holds for six to twelve months. For acne scarring specifically, Rejuran is usually one part of a combined plan rather than a standalone cure; see our acne scar treatment for men overview.

Neither treatment is permanent. Both are maintenance treatments, and the skin gradually returns toward baseline if you stop, which is normal for this category and worth budgeting for.

Risks and side effects

Both treatments have a good safety record when performed by trained injectors using genuine product, but no injection is risk-free.

Common and expected (usually settle within days):

• Redness, swelling and small bumps at injection sites

• Bruising, more likely if you are on blood thinners or fish oil

• Mild tenderness or itching

• Temporary firmness or visible deposits with Skinboosters until the HA spreads

Less common:

• Small nodules or lumps that persist longer than expected

• Infection at an injection site (uncommon with proper sterile technique)

• Asymmetry or uneven results, more a function of technique than product

Red flags: seek urgent medical care if you notice any of the following. These are rare but important:

• Severe or increasing pain that is out of proportion to a few needle marks

• Skin that turns dusky, white, grey or mottled, or develops a blotchy pattern (possible signs of a vascular occlusion, where a vessel is compromised; this is a genuine emergency for any HA injection)

• Spreading redness, heat, pus or fever (possible infection)

• Vision changes, or pain around the eye after periorbital treatment

• Signs of a serious allergic reaction such as facial swelling, hives or difficulty breathing

Reputable clinics that inject HA keep hyaluronidase on site to dissolve filler in the event of a vascular problem, and ask about emergency protocols when you choose where to go. The single biggest determinant of safety here is the skill and preparedness of the person holding the needle.

Choosing a safe clinic in Bangkok

Bangkok has excellent clinics and some that cut corners. Because both treatments are injectables, the choice of clinic is not a detail, it is the main safety decision you make.

Look for:

• A licensed medical clinic where treatments are performed or directly supervised by a doctor, not delegated to untrained staff

• Genuine, traceable product. Ask to see the Rejuran or Skinbooster box and batch, and confirm it is the authentic Korean or branded product, properly refrigerated

• An injector who asks about your medical history and discusses candidacy and contraindications before quoting a price

• Clear written pricing including the number of vials or syringes

• Clean, sterile facilities and a clear plan for managing complications, including hyaluronidase on hand for HA

Red flags worth walking away from:

• Prices that look too good to be true, or pressure to decide on the spot

• Reluctance to show you the product packaging

• No medical consultation, or a "treatment first, questions later" approach

• Vague answers about who is actually injecting you and their qualifications

So which one is right for you?

If your skin mainly looks tired, dry and a bit dull, and you want a visible refresh fairly quickly without changing anything about your face, start with Skinboosters. They are the more affordable entry point and the results show up sooner.

If your concern is firmness, weathering, sun damage or acne scarring, and you are willing to invest in a short course and wait a month or two for it to build, Rejuran is the more appropriate tool because it works at the level of repair rather than hydration.

And for a lot of men, the most sensible plan is not either/or. Because they target different things, the two are frequently used together: Rejuran to rebuild and firm, Skinboosters to keep the surface hydrated and glowing between regenerative cycles. A doctor can sequence them so they complement rather than compete, and tailor the choice of Rejuran sub-type and Skinbooster product to your specific skin.

Whichever route you are leaning toward, the next step is the same. Book a consultation so a clinician can assess your skin in person, confirm you are a suitable candidate and design a plan around your goals. You can explore the treatments themselves on our Skinboosters for men and Rejuran for men service pages, or read the men-focused deep dives on Skinboosters and Rejuran.

Frequently Asked Questions

Can I combine Skinboosters and Rejuran?

Yes, and many men do. Because Skinboosters mainly hydrate while Rejuran mainly repairs and stimulates collagen, the two are complementary rather than competing. A common approach is a Rejuran course to rebuild firmness and texture, with Skinboosters layered in to keep the surface hydrated and bright between regenerative cycles. Your doctor will space the sessions appropriately so the skin is not over-treated, and will tailor which products to use to your skin.

Which one lasts longer, Skinboosters or Rejuran?

Rejuran usually lasts longer. A Skinbooster session typically holds for around four to six months, whereas a Rejuran course commonly lasts six to twelve months. The trade-off is speed: Skinboosters show results within one to two weeks, while Rejuran builds gradually over one to three months. Both are maintenance treatments, so results fade toward baseline if you stop.

Which is better for acne scars?

Rejuran, and specifically the higher-concentration scar formulation, is the better option for acne scarring because it works at the level of tissue repair and collagen remodelling rather than just hydration. That said, for moderate or deep scars it is usually one part of a combined plan alongside treatments such as subcision or pico laser rather than a standalone cure. A consultation will determine the right combination for your scar type.

Do these injections hurt?

Most men describe the discomfort as mild once numbed. Both treatments are delivered as many small microinjections rather than one large jab, and a topical numbing cream is applied for 20 to 30 minutes beforehand. Some Rejuran formulations also contain lidocaine for added comfort. You can expect to feel small pricks and afterwards see minor bumps or mosquito-bite-like marks that settle within a few days.

Is Rejuran safe if I have a fish or seafood allergy?

Raise it with your doctor before treatment rather than assuming either way. Rejuran is made from highly purified salmon DNA in which protein contamination is minimised specifically to reduce the chance of an immune reaction, and allergic responses are uncommon. However, a true fish or salmon allergy is a reason to discuss the risk individually during your consultation so the doctor can decide whether it is appropriate for you.

How much do Skinboosters and Rejuran cost in Bangkok?

As an indicative guide for 2026, Skinboosters run roughly THB 8,000 to 18,000 per session, and Rejuran is about THB 9,000 to 12,000 per vial, which usually works out to around THB 14,500 to 25,000 for a full-face session depending on how many vials you need. A full course of either is lower per session than buying single treatments. These figures are indicative only; confirm the exact price at consultation because it depends on the product, the area and the number of sessions.

How many sessions will I need?

Skinboosters are typically given as a short initial course of one to three sessions, then maintenance every few months. Rejuran usually needs three to four sessions spaced about two to four weeks apart to show its full regenerative effect, followed by periodic maintenance. The exact number depends on your skin, your goals and which product is used, which your clinician will plan at the consultation.

Is there any downtime?

Very little. Both treatments allow most men to return to work or normal activities the same day or the next. You can expect small bumps (Skinboosters) or mosquito-bite-like marks (Rejuran) plus possible minor redness or bruising for 24 to 72 hours. It is sensible to avoid heavy exercise, alcohol, saunas, hot yoga and direct sun for a day or two, and to use sunscreen afterwards.

Do I really need a medical consultation first?

Yes. Both are prescription-grade injectable treatments, and a face-to-face medical consultation is required so a doctor can assess your skin, take your history, confirm you are a suitable candidate and rule out contraindications such as active skin infection, certain allergies, pregnancy, bleeding disorders or a tendency to keloid scarring. The consultation is also where the right product, areas and number of sessions are decided. No reputable clinic will inject without it.
