Depressed scars are a skin concern that bothers you every time you look in the mirror and is difficult to conceal with makeup, leading to deeper worries. The most common question we receive is, "Can a single injection fill in depressed marks?" To answer directly, Juvelook, a collagen booster, can play a role in treating depressed scars. However, it does not work identically for all scars, and its suitability varies depending on the scar's shape and depth.
Hello, this is Yonsei Star Dermatology Sinchon. Today, we will summarize the role of Juvelook, a skin booster that many people are interested in these days, in the treatment of depressed scars.
It's a Collagen Booster, Not Just a Skin Booster
Juvelook is commonly known as a skin booster, but it is more accurate to call it a collagen booster. This is because typical skin boosters are made using hyaluronic acid, while Juvelook focuses on actively inducing collagen regeneration.
Juvelook is well-known for its effectiveness in treating wrinkles, elasticity, and pores. However, good results are also being reported in scar improvement, so Juvelook treatment, which focuses on scar treatment, is actively utilized at Yonsei Star Dermatology Sinchon.
What is Juvelook made of and how does it work?
Juvelook is a PDLLA-component product, a type of poly lactic acid. When injected into the dermal layer of the skin, it stimulates surrounding fibroblasts to promote new collagen production, thereby facilitating skin regeneration.
The core of depressed scar treatment lies in inducing powerful skin regeneration to fill in sunken areas, i.e., promoting collagen production. Because Juvelook aligns with this principle, good results are reported for depressed scars like depressed acne scars.
Background of using collagen boosters for scar treatment
In a paper written by Dr. Jill Waibel in the United States, we learned that applying Sculptra, a collagen booster similar to Juvelook, after CO2 laser treatment for scars showed good results in scar improvement.
However, the collagen booster used in that study was expensive and its particle size was too large to penetrate the skin layer well, posing a risk of nodules. Therefore, despite knowing its effectiveness, it was difficult to actively use it for actual scar treatment.
Then, in 2019, a new collagen booster called Juvelook was developed in Korea, and after attending seminars and its introduction in Korea, it has been used for scar treatment ever since.
Why Juvelook is a good fit for depressed scars
Juvelook is not equally effective for all types of scars. It shows particularly good results for depressed scars because the newly generated collagen fills in the sunken areas from within.
In the clinic, many people who come in for depressed scars also have acne scars. Since many acne scars are depressed, Juvelook is often used together with acne scar treatment.

Suitability varies depending on scar shape
Acne scars can be broadly divided into three types based on their shape, and Juvelook's suitability also varies by type.
| Scar Type | Shape Characteristics | Juvelook Suitability |
|---|---|---|
| Rolling | Round, wide depression | Good results reported |
| Boxcar | Square with distinct borders | Limited use alone |
| Icepick | Narrow, deep depression | Limited use alone |
Juvelook shows particularly good effects on rolling scars, which are wide and uneven. This is because it is suitable for filling large areas with new collagen.
On the other hand, boxcar and icepick scars are small in area and have narrow borders, making it difficult to fill only those parts. Therefore, Juvelook is not typically used alone for these types.
Expect better results when combined with laser treatment
Depressed scars can be treated with Juvelook alone, but combining it with CO2 fractional laser often leads to better results. In such cases, we recommend 3 to 5 sessions of Juvelook treatment along with laser treatment.
Its mechanism of action also differs from hyaluronic acid products commonly used as scar fillers. Hyaluronic acid has a significant filling effect when first injected, but it degrades and diminishes over time. In contrast, Juvelook's initial filling effect may diminish relatively quickly, but it continuously stimulates fibroblasts from within to create new collagen, and its effects are maintained for a long time.
Here are some additional approaches to consider for different scar types:
- For rolling scars with wide depressions, prioritizing collagen filling is key.
- For boxcar scars with distinct borders or deep icepick scars, consider combining with laser or other methods.
- For acne scars with mixed forms, design a combination treatment with Premium Customized Acne Scar Care.
- The number and interval of treatments may vary individually depending on skin condition.
In summary
Today, we looked at the role of Juvelook in treating depressed scars. Juvelook, a collagen booster also used for improving pores, elasticity, and fine wrinkles, shows good results for depressed scars, especially rolling-type depressions. However, its suitability varies depending on the scar's shape and depth, and whether it should be combined with laser treatment also differs. Therefore, it is best to confirm the appropriate approach for your scar through a consultation.
