Uneven, depressed scars are a skin concern that bothers you every time you look in the mirror and is frustratingly difficult to conceal with makeup. A common question we receive is, "Can laser treatment alone fill in depressed marks?" To answer directly, when fractional laser refines the surface and Juvelook simultaneously induces dermal collagen production, we approach it by filling both the surface and the deeper layers.
Today, we will explain the principles behind acne depressed scar treatment using Juvelook at Yonsei Star Dermatology Sinchon.
Depressed Scars: Why Laser Alone Isn't Enough
Depressed acne scars refer to a condition where acne inflammation damages the dermal tissue, causing the area to sink. Since the damaged area remains like an empty space lacking collagen, it is often difficult to fill the entire depth by only refining the surface.
Therefore, while fractional lasers, often called depressed scar lasers, refine the epidermis and superficial dermis, it is also necessary to simultaneously replenish collagen deep within the dermis. Juvelook is used in conjunction to complement this deficiency.
Why Juvelook, Known as a Skin Booster, is Also Used for Scars
Juvelook is commonly known as a skin booster for improving skin texture and elasticity, but it is also used to fill depressed scars. This is why Yonsei Star Dermatology Sinchon has incorporated Juvelook into scar treatment.
Juvelook is known to stimulate fibroblasts in the skin to induce new collagen production. As collagen builds up, the sunken areas are gradually filled. Clinically, changes where depressed areas are filled are generally observed after about 6 months, and the speed and extent of progress may vary from person to person.
Juvelook and Fractional Laser: Why They Go Together
The key is to combine Juvelook not as a standalone treatment, but with fractional devices like RePott Laser, which are known as depressed scar lasers.
The laser stimulates the tissue around the scar to create a regenerative environment, and then Juvelook fills in the collagen. When the surface refining and internal filling processes align, we expect the depth and borders of the scar to soften.
The composition and interval of combined treatments may vary depending on the scar type. Therefore, at our clinic, we design combinations tailored to individual scar types, such as Premium Customized Acne Scar Care.
It is reported that depressed scars are not perfected by a single method, but rather lead to more natural changes when surface-refining lasers and collagen induction for filling the inside are combined step by step.

How Scar Fillers and Juvelook Differ
Many people consider scar fillers and Juvelook to be the same, but there are clear differences in their mechanism of action and duration.
| Category | Scar Filler | Juvelook |
|---|---|---|
| Main Ingredient | Hyaluronic Acid | Collagen Induction (CIT) |
| Effect Pattern | Appears filled immediately after treatment | Gradually fills over time |
| Duration Trend | Gradually diminishes as it breaks down | Long-term expectation as collagen settles |
Fillers, being hyaluronic acid, appear to fill immediately after treatment, but their effect tends to diminish over time as they break down. On the other hand, even if the change is not immediately apparent, Juvelook continuously stimulates fibroblasts to produce collagen, so the long-term outcome can be summarized as different.
Important Points to Remember for Treatment Effectiveness
In the examination room, we observe that patients who consistently follow the treatment plan achieve more stable results, even with the same procedure. Since depressed scar treatment is difficult to complete in one session, it is good to keep the following in mind:
- Consistently complete the prescribed number of sessions rather than expecting immediate filling after one or two treatments.
- Consult with medical staff to determine the appropriate combination of laser and Juvelook for your scar type.
- Adhere to the recommended intervals between treatments to allow time for collagen to settle.
- Combine basic care such as UV protection and moisturizing after the procedure.
- Even if changes feel slow, check the progress with your doctor rather than discontinuing arbitrarily.
Our clinic's dermatologists confirm the scar type through individual consultation and then guide you to the appropriate treatment direction.
In Summary
For depressed acne scars, combining fractional laser to refine the surface with Juvelook to fill the deeper layers addresses both the surface and depth. However, the appropriate composition and number of sessions vary depending on the depth and shape of the scar and skin condition, so it is best to establish a personalized plan through consultation.
