Hello,
This is Human Dermatology Clinic Seoul National University Branch.
If your skin has become more easily dry than before, and makeup tends to sit unevenly or fine lines stand out, it may be more than just surface dryness. The skin’s ability to retain moisture may have weakened, and as collagen and elasticity structures gradually break down, the skin’s natural recovery ability may have declined.
One of the treatments many people look for in such cases is Rejuran. Rejuran is not simply a care treatment that makes the skin surface look moisturized; it is a Sillim Rejuran skin booster treatment that approaches the skin by improving the internal environment and enhancing regeneration. It is a suitable option for those who want to naturally address skin texture, elasticity, moisture, and fine lines together.

Sillim Rejuran: Bringing vitality and elasticity back to dull skin
Human Dermatology Clinic, Seoul National University Branch

What is Rejuran?
Rejuran is a regenerative skin booster based on PN extracted from salmon DNA. PN is known as an ingredient that helps damaged tissue recover from within the skin and encourages the skin to regain a healthy state on its own. In particular, it has a structure that is more than 95% similar to human DNA, so it is considered relatively biocompatible.
Because of these characteristics, the burden of immune reactions or allergies is known to be relatively low, and even those with thin or sensitive skin may consider the treatment through a consultation for Sillim Rejuran. When you feel that both elasticity and moisture have decreased, Sillim Rejuran can be approached as a treatment that restores the skin’s internal condition rather than a simple moisturizing care treatment.

What effects and benefits does Rejuran provide for the skin?
The greatest advantage of Rejuran is that it helps damaged cells inside the skin recover and induces collagen production, thereby enhancing the skin’s natural strength. When the skin becomes thinner and loses elasticity, fine lines, enlarged pores, rough skin texture, and dryness often appear together. Rejuran can help by organizing the internal skin environment in a healthier way in response to these changes.
After a Sillim Rejuran procedure, you may expect skin regeneration and improved elasticity, improved skin texture and pores, reduced fine lines, and restored skin tone and vitality. Of course, not all changes are completed with a single treatment, and depending on the individual’s skin condition and degree of aging, repeated treatments or combination with other device-based procedures may be necessary. The important thing is to manage the skin in a way that makes it look naturally better rather than aiming for excessive change.

These areas can be treated
Rejuran can be applied to the entire face as well as areas where fine lines tend to form easily. It can be used in areas such as around the eyes, around the mouth, and the forehead, where the skin is thin and facial movements are frequent. In these areas, improvement is often difficult with moisturizing alone, so it is important to manage the regenerative environment within the skin as well.
It can also be considered for areas such as the upper cheeks and cheeks, where a loss of elasticity is felt, or when moisture and radiance across the entire face have declined. The neck area, where signs of aging are easily visible, can also be included in a treatment plan through consultation. However, because skin thickness, sensitivity, and pain level differ by area, Sillim Rejuran requires careful adjustment of injection depth and dosage.

Rejuran is recommended for these people
If your skin is generally dull and has lost elasticity, or if makeup sits unevenly and your skin texture looks rough, you may want to consider Rejuran. It may be especially suitable for those with thin, sensitive skin that reddens easily, or for those whose fine lines are increasing as dryness repeats. Sillim Rejuran can also be approached as a natural skin improvement option for those who find volume-filling procedures 부담스러운.
It may also help those with uneven skin texture due to acne scars or skin damage, or those whose skin has aged due to dryness and loss of elasticity. People who want treatment but are worried about their face changing unnaturally often prefer procedures like Sillim Rejuran that enhance the skin’s natural recovery ability. If you want a natural and healthy change in your skin, it is a treatment worth consulting about.


Rejuran is a skin booster that helps skin regeneration, but simply injecting good ingredients does not produce the same result for everyone. Depending on skin thickness, sensitivity, the location of fine lines, pore condition, and the degree of elasticity loss, the injection area, depth, dosage, and treatment interval should all differ. In particular, more delicate approaches are needed for areas with thin skin, such as around the eyes or mouth.
Therefore, it is important to proceed with a Sillim Rejuran treatment after 충분한 consultation with a dermatologist who accurately understands the skin structure and can plan according to the individual’s skin condition. Even with the same Rejuran, satisfaction can vary depending on who receives it, how it is performed, at what depth, and to what extent. If you want healthy and natural skin changes, we hope you will approach it not as a simple trend treatment but as a regenerative care treatment of Sillim Rejuran suited to your skin.
