Products
The Rejuran range
Four formulations of the same polynucleotide, chosen by area and by what the skin needs.
The original. Injected across the whole face in a fine grid to repair the barrier, improve elasticity and refine texture. The standard choice for dull, thin or sun-damaged skin and the booster most often combined with laser or RF microneedling.
₩350,000 / 2cc · ₩550,000 / 4cc
Healer blended with non-cross-linked hyaluronic acid. Gives immediate hydration and glow on top of the regenerating effect, with less post-injection bumpiness; chosen for dehydrated skin and for patients who want a visible result quickly.
₩450,000 / 2cc · ₩750,000 / 4cc
A lower-viscosity, lower-concentration formulation for the thin skin around the eyes. Softens fine lines, crepiness and dark shadows under the eye where filler would be too heavy. Often paired with Eye Thermage or Eye Xerf.
₩250,000 / 1cc · ₩400,000 / 2cc
A thicker formulation injected directly into depressed acne scars and surgical scars to lift the scar bed and speed regeneration after subcision, CROSS or laser. Used inside the combination acne-scar programme rather than on its own.

What it does
The active ingredient is a polynucleotide (PN) derived from salmon DNA, injected to stimulate fibroblast activity and tissue repair. The result is better barrier function, elasticity and fine texture. Rejuran i, a lower-viscosity formulation, applies this same principle to the more delicate eye area, and the same PDRN mechanism is used elsewhere in the clinic's scar programmes to speed up regeneration.
How it is planned here
The product is delivered into the dermis in an even grid, either with a fine needle or an automated injector, after numbing cream has been applied. It's common to pair this with a laser or RF microneedling session in the same visit, since the regenerating effect helps support healing from the other treatment.
What to expect
Small bumps are visible for one to two days after injection. Texture continues to improve over two to four weeks, with a typical course of three monthly sessions followed by maintenance twice yearly.
Questions
Rejuran or Juvelook?
Rejuran repairs and hydrates; Juvelook stimulates collagen for pores and density. Many programmes use both, in different zones.
Does it hurt?
Numbing cream makes it tolerable; the eye area is more sensitive.
Downtime?
One to two days of visible bumps.
What is a skin booster, in plain terms?
A series of tiny injections just under the skin that improve its quality: hydration, smoothness, firmness, pores. It is not a filler, so it does not change your shape; it changes how the skin itself looks and feels.
Which booster is right for me?
That is decided by zone from the Mark-Vu skin analysis, not by brand. Thin, dehydrated skin needs a repair booster such as Rejuran; pores and texture need a collagen stimulator such as Juvelook; deflated areas need a volume stimulator such as Sculptra. Many plans use two products in different zones.
Will people be able to tell I had something done?
Small bumps at the injection points are visible for one to three days and are easily covered with makeup. There is no change in your features.
How many sessions do I need?
Hydrating boosters: three sessions a month apart, then maintenance twice a year. Collagen stimulators: two to three sessions, with the result building over two to three months. A single session still gives a visible improvement.
Is the product genuine?
Yes. The clinic uses only authenticated original vials and shows you the product before injection. The amount agreed at consultation is the amount injected.
