Hello.
This is Doctor O Clinic.
The concern and desire for beauty never end.
And that beauty may begin with skin elasticity.

We dream of firm, lively, youthful skin, but as we age, elasticity gradually disappears, the skin becomes thinner and duller, and wrinkles become more noticeable.
Frequent UV exposure, stress, lack of sleep, irregular eating habits, and many other factors in our daily lives destroy collagen and elastin in the skin, leading to fine lines around the eyes and mouth and overall skin sagging.
However, if you rely only on cosmetics that simply fill the surface or temporary lifting treatments to prevent these changes, the skin's fundamental recovery will not happen.
True, healthy elasticity must begin deep within the skin.
That is why the solution many experts are paying attention to is 'REJURAN,' which restores the skin's natural ability to recover.
Rejuran: Redesigning the Skin.
Rejuran is a skin regeneration injection whose main ingredient is polynucleotide (PN), a biocompatible substance extracted from salmon.
PN promotes the regeneration of damaged cells and strengthens the structure of the dermis, helping the skin regain health on its own.

In particular, salmon DNA, which has a high similarity to human skin, has a low risk of side effects and causes minimal irritation, making it suitable even for sensitive skin.
The key effects of Rejuran are as follows.
▶ Restores skin elasticity: Promotes collagen production to firmly rebuild the skin structure.
▶ Improves wrinkles: Reduces everything from fine lines to deeper wrinkles and refines skin texture.
▶ Strengthens the skin barrier: Reinforces the structure that protects the skin from external irritants.
▶ Improves tone and texture: The skin is evenly restructured, resulting in a smooth and clear complexion.

Doctor O Clinic Rejuran
At Doctor O Clinic, we maximize the effects of Rejuran with a precise, personalized skin recovery program.
- Precise skin diagnosis with Mark-Vu
Using advanced equipment that can analyze not only the skin surface but also the dermis, we accurately assess pores, wrinkles, pigmentation, and elasticity.
Through this, a customized Rejuran treatment is carried out to match each patient's skin condition.
- Pain-free anesthesia system introduced
Through a total of three steps—an anesthetic cream that works deeper than conventional methods, cooling anesthesia, and pain-relief anesthesia—we reduced pain and increased comfort.
The simplified process takes about 15 minutes, ensuring both efficiency and safety.
- Hand injection method without drug loss
Instead of an injector, the treatment is carefully administered to the necessary areas by Director Oh Jeong-min, who has 11 years of experience, using manual injections.
By adjusting the injection depth and amount according to skin type and area, natural and quick recovery is possible.

If you dream of truly youthful skin, change from the inside, not just the outside.
Rejuran is not simply a treatment that fills the skin; it is an 'essential improvement' procedure that stimulates the skin to recover on its own.
Long-lasting elasticity, natural and lively radiance, and a healthy skin barrier that does not easily collapse even under external irritation—all of this is possible through Rejuran.
After the procedure, sun protection, hydration, and a balanced lifestyle can help the regenerative effects last longer.
Doctor O Clinic will be with you on your journey to truly elastic, youthful skin.
