Hello, this is Doctor O Clinic.
One of the representative procedures for skin regeneration and improved elasticity is Rejuran.
Rejuran contains PN (polynucleotide) extracted from salmon and is known to promote skin regeneration, improve elasticity, and enhance overall skin health.
However, because the effects and purposes of Rejuran vary by type, it is important to choose the one that matches your skin concerns.
Among them, the two most commonly used types, Rejuran Healer and Rejuran HB, have different characteristics.

Rejuran Healer & Rejuran HB: what effects do they have?
Regeneration from within the skin
Rejuran penetrates deep into the skin and promotes cell regeneration.
This helps the skin recover on its own and restores damaged skin to a healthier state.
Improved elasticity & wrinkle reduction
By activating collagen and elastin production, skin elasticity increases, and fine lines as well as deeper wrinkles are improved.
Hydration & improved skin texture
In particular, Rejuran HB contains hyaluronic acid, which provides an immediate moisturizing effect to the skin and helps improve internal dryness, leaving the skin hydrated and smooth.
Strengthened skin barrier
By enhancing the skin’s regenerative ability, the skin barrier becomes stronger and the skin improves into a healthier state that is more resistant to external irritation.

Rejuran procedures at Doctor O Clinic
Direct 1:1 treatment by an experienced CEO director
Rejuran is not a simple skin injection; it is a procedure where precise technique matters, as the depth and amount must be adjusted according to the skin condition. At Doctor O Clinic, CEO Director Oh Jeong-min, who has extensive experience with Rejuran procedures, performs the treatment directly to provide more precise and effective results.
More comfortable with painless anesthesia
Because Rejuran is injected deep into the skin, it can involve discomfort.
At Doctor O Clinic, the Painless anesthesia system is introduced, making it possible to receive the procedure comfortably and without burden, even without sleep anesthesia.
Customized treatment after an accurate skin diagnosis
Rejuran Healer and Rejuran HB have different purposes and effects, so we recommend the appropriate Rejuran after a detailed diagnosis of your skin condition.
There are many places that perform Rejuran procedures, but optimal results can be achieved when the correct method, experienced medical staff, and delicate techniques to reduce pain are combined.
At Doctor O Clinic, we will carefully analyze each customer’s skin concerns and provide the optimal solution suited to your skin type, delivering the most satisfying Rejuran procedure.
