Regeneration is one of the most used words in Korean aesthetics, from salmon DNA boosters to exosomes. This guide looks honestly at what the evidence supports, what is still uncertain and how to make sensible choices in Seoul.
Korean skin regeneration treatments aim to help skin repair and renew itself, using polynucleotides (Rejuran), exosomes, collagen stimulators (Juvelook, Sculptra) and energy devices. Evidence is strongest for collagen stimulators and well-established devices such as RF microneedling and fractional lasers, moderate for polynucleotides, and still early for exosomes. No treatment reverses aging. At Dernia Clinic Myeongdong in Seoul, Rejuran Healer starts from ₩259,000 and exosome therapy from ₩190,000 with microneedling (KRW, excluding 10% VAT).
Prices are in Korean won, exclude 10% VAT and are confirmed by a doctor at consultation.
What does skin regeneration mean?
In dermatology, regeneration describes the skin's ability to repair itself and renew its structure, including collagen, elastin and the outer barrier. Every day, skin cells are replaced and damaged proteins are cleared. With age, sun exposure and inflammation, that process slows, and skin becomes thinner, less elastic and slower to heal.
Regenerative treatments try to support or stimulate this natural process. Some do it by creating a controlled injury that the skin repairs, such as fractional lasers and microneedling. Others supply materials or signals thought to help cells repair, such as polynucleotides and exosomes. Others trigger collagen production directly, such as PDLLA and PLLA stimulators. In Korea, these are often combined in one plan, which makes it harder to know which part did the most work.
How strong is the evidence for each treatment?
Evidence quality varies a lot. This summary reflects the general state of published research and clinical experience, not guarantees for any individual.
| Treatment | How it works | Evidence level | Price from at Dernia (KRW) |
|---|---|---|---|
| Fractional lasers (CO2, pico fractional) | Controlled micro-injury triggers remodeling | Strong, long track record | ₩149,000 (pico fractional) |
| RF microneedling (Potenza) | Heat at depth stimulates collagen | Good, widely studied | ₩299,000 |
| PLLA stimulator (Sculptra) | Particles trigger collagen formation | Good, long track record | ₩590,000 (1 vial) |
| PDLLA stimulators (Juvelook, Lenisna) | Particles trigger collagen formation | Moderate, growing | ₩299,000 (Juvelook, 2cc) |
| Polynucleotides (Rejuran) | Supports repair; holds water | Moderate, mostly smaller studies | ₩259,000 (2cc) |
| Exosome therapy | Cell-signaling vesicles applied after microneedling | Early, still developing | ₩190,000 |
Energy-based devices: the strongest evidence
Fractional lasers and RF microneedling have been studied for many years. Their mechanism is well understood: a controlled micro-injury prompts a healing response that remodels collagen. Results for acne scars, texture and fine lines are well documented, though they vary by skin type and settings. See Potenza and CO2 fractional laser.
Collagen stimulators: good and growing evidence
PLLA (Sculptra) has a long clinical history for volume restoration. PDLLA products such as Juvelook are newer but are widely used in Korea, with a growing body of clinical experience. Their effect on collagen is gradual and visible over months. See Sculptra.
Polynucleotides: promising, moderate evidence
Polynucleotide boosters such as Rejuran Healer are popular in Korea and have supportive studies, particularly for skin quality and repair. Many studies are relatively small or short-term, so results should be described cautiously. See Rejuran Healer.
Exosomes: early evidence
Exosomes are tiny vesicles that cells use to send signals. In aesthetics, exosome serums are applied to skin after microneedling or laser to support recovery. Laboratory research is promising, but high-quality clinical evidence in humans is still limited, and products vary widely in source and quality. We treat exosomes as a supportive add-on, not a standalone fix. See exosome therapy.
Treatments Dernia does not offer
Dernia does not currently offer standalone PDRN injections or Rejuran S. If you are interested in those, your doctor can explain alternatives that address the same goals.
How to judge regeneration claims
- Look for the mechanism. Is there a clear explanation of how it works in skin?
- Check the study type. Laboratory or animal studies are a starting point, not proof of cosmetic results.
- Consider study size and length. Small, short studies suggest possibilities but rarely confirm them.
- Be wary of dramatic promises. Phrases like reverses aging or regrows skin are marketing, not medicine.
- Ask your doctor directly. A good doctor will tell you what is well established and what is not.
Our questions to ask at your consultation guide can help.
Who is a good candidate for regenerative treatments?
Usually a good fit
- Thin, fragile or slow-to-recover skin
- Texture changes, fine lines or acne scars
- People wanting gradual, natural improvement
- Those comfortable with evidence-based expectations
Talk to the doctor first
- Fish allergy, for salmon-derived products
- Active infection, acne flare or open wounds
- Pregnancy, breastfeeding or autoimmune conditions
- Expecting dramatic or permanent results
What results can you realistically expect?
Regenerative treatments share one feature: they work on the skin's own timeline. Because new collagen and healthier tissue take weeks to form, the change is gradual. That is an advantage for people who want natural-looking results, but it can be frustrating if you expect to see a difference the next morning.
- First days: redness, bumps or swelling depending on the treatment. Any early plumpness is mostly swelling or hydration.
- Weeks 2–4: the skin may look calmer, smoother or more hydrated, especially after boosters.
- Months 2–3: collagen-based changes become clearer after devices and stimulators.
- After a series: most people see healthier, firmer, more even skin rather than a dramatic transformation.
Lifestyle has a large influence. Daily sunscreen, not smoking, enough sleep and a gentle skincare routine all support the skin's ability to repair, and they help any treatment last longer. Without them, even well-evidenced treatments give shorter-lived results.
Recovery and aftercare
Aftercare depends on the treatment, but the principles are similar. For the first day or two, avoid saunas, hot baths, intense exercise and alcohol. After microneedling or lasers, keep the skin clean, moisturized and protected from the sun, and avoid makeup until your doctor says it is fine, usually the next day. Pause retinol and exfoliating acids for several days. After collagen stimulators, follow any massage instructions you are given. Read aftercare after laser treatment for practical detail.
Is it safe? Risks and side effects
Most regenerative treatments are well tolerated when performed by trained doctors. Common effects include redness, swelling, bumps and bruising. Devices can cause temporary darkening of the skin, especially in darker skin types or after sun exposure. Collagen stimulators carry a small risk of nodules. Polynucleotide and exosome products depend on careful sourcing; ask what product is being used and where it comes from.
