Dermal Repair Therapy in Seoul: Rebuild Damaged, Thin Skin

The short answer

Dermal repair therapy rebuilds the deeper skin layer with regenerative injectables and gentle collagen stimulation, so thin, damaged or over-treated skin becomes thicker and more resilient. In Seoul a session usually combines a PN booster such as Rejuran, exosomes or low-energy microneedling, costs about ₩200,000–₩700,000, and needs three to four sessions two to four weeks apart. Downtime is typically one to three days.

What dermal repair therapy means

Most cosmetic treatments work on the surface or on lifting. Dermal repair therapy focuses on the dermis, the middle layer of skin that holds collagen, elastin and hydrating molecules. When the dermis is healthy, skin looks plump, recovers quickly and tolerates treatments well. When it is thin or damaged, skin becomes fragile, reactive and slow to heal.

In Seoul this approach is popular with patients who have had many lasers, who live in harsh climates, or who simply feel their skin has lost its strength.

Signs your dermis needs repair

• Skin that looks thin, crepey or slightly translucent
• Persistent redness or stinging after products or treatments
• Fine texture lines and loss of bounce
• Slow healing after acne, scratches or laser sessions
• Sun damage with dullness and uneven tone

The main treatments used

PN and PDRN skin boosters

Polynucleotide boosters, best known as Rejuran, are injected in small blebs across the face. They are thought to support the skin's own repair processes and are widely used in Korea for thin and sensitive skin. Learn more on our Rejuran injection page.

Exosomes and growth-factor serums

Applied after microneedling or laser, these cell-derived products aim to calm inflammation and speed recovery. See our exosome skin therapy guide for how they are used.

Low-energy collagen stimulation

Gentle microneedling, low-energy RF or fractional laser triggers controlled healing without overwhelming fragile skin. The settings are deliberately lower than for scar treatment.

LED and calming care

Red and near-infrared LED and soothing masks are often used at the end of a session to reduce redness.

How a programme is structured

Most patients need three to four sessions, two to four weeks apart. Improvement is gradual: skin often feels calmer after the first session, while thickness and texture improve over two to three months. If you can only visit Seoul once, ask the clinic for a single intensive session plus a home routine, and consider repeating on your next trip.

Who should consider it

Dermal repair therapy suits people with sensitive, thin or sun-damaged skin, and those preparing for or recovering from stronger treatments. It is not a lifting treatment; if sagging is your main concern, combine it with tightening or read about elasticity boost treatments.

Aftercare

• Avoid makeup for 12–24 hours after injections
• Skip exfoliating acids, retinoids and scrubs for about a week
• Use a simple moisturiser and broad-spectrum sunscreen
• Avoid saunas, alcohol and hard exercise for one to two days

Questions to ask the clinic

• Which booster brand and how many millilitres are included?
• Is the injection done by hand or with a device, and is numbing used?
• What home products do you recommend between sessions?

Patient questions

Frequently asked questions

Is dermal repair therapy the same as Rejuran?

Rejuran is often part of it, but dermal repair therapy is broader and may include exosomes, gentle microneedling and LED.

Does it hurt?

Booster injections sting briefly even with numbing cream. Most people find the session very manageable.

When will I see results?

Skin often feels calmer within a week. Firmer, thicker skin develops over two to three months.

Can I do it before a flight?

Yes, but small injection bumps can last a day or two, so allow at least 24–48 hours if you want to look fully settled.
