Retijen Collagen Injection in Gangnam

How it works

Retijen is an injectable collagen product. Its main ingredient is highly purified type I atelocollagen, collagen from which the telopeptide ends, the parts most likely to trigger immune reactions, have been removed. Injected into the dermis, it directly replenishes collagen in areas where it has thinned, and it is described as having a neutral pH to help keep swelling and discomfort low. It is aimed at improving skin texture, fine lines and shallow scars rather than adding significant volume.

Who it's for

It is typically considered by adults with fine lines, enlarged pores, thin skin, or shallow atrophic acne scars, including delicate areas such as around the eyes. It can be used alone or combined with lasers, subcision, or other skin boosters. Retijen is among the treatments publicly listed by The Heal branches.

What to expect at The Heal Sinsa

At The Heal Dermatology Sinsa Main Branch, near Sinsa Station and Garosu-gil in Gangnam, your consultation and treatment are carried out 1:1 by a Korean board-certified dermatologist. The dermatologist reviews your skin and allergy history, explains how a collagen injection compares with polynucleotide or hyaluronic acid boosters, and plans the areas and number of sessions. We aim for honest recommendations without overselling, use genuine full-dose products, and treat in private single rooms. English and Traditional Chinese support is available on request. Pricing is confirmed after consultation; see pricing and payment.

Risks & who should avoid

Common effects include injection bumps, redness, swelling and bruising.

Retijen is generally avoided during pregnancy or breastfeeding, with active skin infection, autoimmune conditions under active treatment, or known allergy to product components.

Planning around your trip to Seoul

With only a day or two of minor bumps, a session can fit into a short stay; a full series suits repeat visits. See combining treatments in one trip. See international patients and getting here for practical details.

How is Retijen different from Rejuran?

Retijen supplies collagen directly to the skin, while Rejuran uses polynucleotides to support the skin's own repair processes. Both aim to improve skin quality but work differently. The dermatologist recommends one or a combination based on your concerns.

Does Retijen add volume like filler?

No. Retijen is used to improve skin texture, fine lines and shallow scars rather than to add noticeable volume or change facial shape. For volume loss, fillers or collagen stimulators such as Sculptra may be discussed instead.

Is Retijen safe for sensitive areas like under the eyes?

Collagen injections are commonly used in delicate areas, including around the eyes, when performed carefully by a trained doctor. Bruising and small bumps are possible. The dermatologist will assess whether it is appropriate for your skin and goals.
