Hello.
This is Owoon Clinic Samseong Branch, your dedicated skin clinic.
Skin is the body’s largest organ and the first line of defense against the external environment. But over time, it loses elasticity and develops fine lines.
This is not simply because of age. It happens as collagen and elastin in the dermis, which lies deep within the skin, decrease, causing the skin to gradually become thinner and weaker.
That is why skin booster procedures are gaining a lot of popularity. They can effectively address various skin concerns by injecting different active ingredients into the skin.

Among them, the most representative procedure is Rejuran Healer. This treatment continues to remain popular thanks to its unique active ingredient.
Today, I’d like to talk about a procedure that is effective for a variety of skin concerns.
You should definitely know the key active ingredient of Rejuran Healer.

Before explaining Rejuran Healer, let me briefly talk about the structure of the skin. The skin is broadly divided into the epidermis, dermis, and subcutaneous fat layer. Among these, the dermis is where collagen and elastin, which determine skin elasticity, are distributed.
This dermal layer is only about 1 to 2 mm thick, but it is the central structure responsible for the overall health and elasticity of the skin. However, as we age, the collagen in this layer gradually decreases, and the skin becomes thinner and weaker, eventually showing up as wrinkles and sagging.
In other words, the dermis can be said to be the core support of the skin.
Rejuran Healer is a skin booster aimed at skin regeneration and is often known by the nickname “salmon injection,” because the main ingredient, polynucleotide (PN), is derived from salmon.
PN has excellent biocompatibility with the human body, so it is naturally absorbed into the skin and promotes self-regeneration. In particular, PN is highly effective in repairing damaged tissue, reducing inflammation, and increasing skin elasticity and thickness.
By accurately injecting this ingredient into the dermis, the thickness and density of the dermis increase, which can effectively improve skin concerns.
Many people are already improving their skin concerns through Rejuran Healer.

Numerous studies published so far have shown that PN promotes collagen production in the dermis and helps activate fibroblasts.
One paper reported that after three Rejuran Healer treatments in 50 women with an average age of 40, skin elasticity increased by an average of 23%, and the depth of fine lines decreased by 18% (Journal of Cosmetic and Laser Therapy, 2022). Such data show how effective Rejuran Healer is for skin regeneration.
So if you ask what the biggest advantage is, I would say the effect. Even without my explanation, many people continue to receive ongoing care with Rejuran Healer.
Because it acts directly on the “dermis,” unlike general skincare that only works on the skin surface, changes begin deep within the skin, and lost elasticity and moisture can be restored so the skin can return to a healthy and vibrant state.
No matter how good a procedure is, it only works when performed properly.

Simply injecting the medication does not produce satisfying results. This is because whether the procedure succeeds depends greatly on how accurately the medication is delivered and at what appropriate depth.
As mentioned, the dermis is located just below the epidermis and is very thin. That is why injection is so difficult.
If the needle goes in too deeply, the medication can flow into unnecessary areas, and if it is too shallow, it may remain on the skin surface and reduce the effect.
That is why many clinics use equipment to assist with injection. This has the advantage of reducing pain and maintaining a uniform injection depth. However, it is unavoidable that not all of the product is injected and some is wasted.

That is why at Owoon Clinic, we recommend direct manual injection by an experienced doctor. Even if the injection is uniform, if there is already product loss, the effect will naturally be reduced. In addition, since the procedure cost is not low, wasting the product is a major drawback.
At our Owoon Clinic, we carefully inject one point at a time without being constrained by time to ensure accurate delivery. In addition to precise injection, we perform the optimal procedure by making subtle adjustments to the amount used depending on the treatment area and adjusting the depth according to each client’s skin.
Because we adjust the treatment by injecting more shallowly in thin skin layers and deeper in areas where fine lines are more prominent, we can deliver the product without waste.
So, this was a look at Rejuran Healer. This procedure is not simply meant to make the skin “look better”; it induces regeneration from within the skin to help restore true health. It is highly recommended for those concerned about dryness or fine lines, so please visit for an evaluation and receive the most suitable treatment.
