If you feel that self-care has reached its limits in dealing with recurring acne, we recommend cosmetic medical treatments. In this article, we’ll introduce seven types of cosmetic medical treatments suitable for acne and acne scars. Learn about the characteristics of each and choose the treatment that’s right for you to achieve your ideal skin.
What kinds of concerns are associated with acne?

Acne is a chronic inflammatory skin condition.This refers to a condition in which sebum accumulates in the pores, which can sometimes lead to inflammation.. Whether it’s recurring red or yellow acne, or even when things seem to have calmed down, you’re still plagued by post-inflammatory redness (hyperpigmentation) and acne scars (craters)—the worries never end.
Even if you take great care with self-care, your symptoms may not subside, and you may feel like you’ve reached your limit.
What Causes Acne and Acne Scars?

So, what are the causes of acne and acne scars? Let’s take a look at each one.
[Acne]
- Excessive secretion of sebum
- Clogged pores
- Proliferation of Acne-Causing Bacteria
Excessive sebum production and clogged pores, which are the underlying causes, are,Cases caused by lack of sleep or an irregular lifestyleAlso, while Propionibacterium acnes is a naturally occurring bacterium found in pores, when it multiplies, it can cause inflammation and lead to acne. While some people have struggled with acne since their school days, others may feel that their breakouts have suddenly increased as they’ve become adults.
[Acne Scars]
- Redness: Dilated capillaries and thin skin
- Pigmentation: Excessive melanin production caused by inflammation
- Craters: Collagen and elastin in the dermis are destroyed
Even after the inflammation from acne subsides, redness may remain temporarily. In cases of particularly severe inflammation, there is a risk of hyperpigmentation or scarring. You should be careful not to squeeze pimples, as doing so can sometimes worsen the inflammation by trapping sebum inside.
Peeling (Mint Peel)

If you're struggling with acne, the first thing you should consider is a chemical peel.
Apply the product to your skin to remove dead skin cells and impurities from your pores. It helps promote skin renewal and leads to healthier skin. In addition to reducing clogged pores and dark spots, it helps regulate sebum balance.
We especially recommend using the Mint Peel solution for those concerned about acne and acne scars.Formulated with salicylic acid, which is effective against acne, and menthol, which provides a cooling sensationThis is a key feature of the treatment. It minimizes the sensation of heat during the peel while leaving you feeling refreshed afterward.
The peeling treatment takes about 20 minutes.Treatment once every 1 to 2 weeks, for a total of about 4 to 6 sessions, is effective.. Since your skin may peel after treatment, be sure to moisturize thoroughly.
Alexandrite Laser Facial

Next, I’ll tell you about the Alexandrite laser facial.
Using an alexandrite laser, this treatment targets the sebaceous glands and acne-causing bacteria deep within the skin. It promotes skin renewal, leading to firmer, more supple skin.
The alexandrite laser, which targets melanin, is actually used for hair removal as wellIt is a type of laser. In addition to treating and preventing acne, it helps exfoliate the surface of the skin and shrink sebaceous glands.. You should be able to achieve a clear, radiant complexion.
Each session lasts about 45 minutes.You can expect to see results after about 5 to 10 sessions.. After your treatment, be sure to protect yourself from UV rays. Be sure to use sunscreen and wear a hat.
Trifill PRO

Tri-Fil Pro is a type of subcision treatment that is effective for improving acne scars.
First, carbon dioxide is injected using an ultra-fine needle to detach the hardened skin tissue that causes acne scars. After reinjecting the carbon dioxide, a medication tailored to the specific concern is evenly applied.
Effective for various types of acne scarsTry Fil Pro. Depending on your specific concerns, you can choose from treatments such as Jubelook or Rejuran i, which can help prevent recurrence.
A treatment session lasting about 20 to 30 minutes, once a month,It's most effective to do this about three times in total.. One of its key features is that it reduces the risk of bleeding and hyperpigmentation compared to conventional subcision treatment.
Subcision

For those struggling with particularly deep acne scars, subcision may be an option to consider.
Subs. are,A treatment in which areas where the skin's surface is indented due to adhesions in the deeper layers of tissue caused by inflammation are separated using a special needleBy eliminating the force that pulls the skin downward, it helps create smooth skin where unevenness is less noticeable.
This treatment can help reduce the appearance of acne scars, such as rolling scars and deep boxcar scars. In particular, injecting Jubelook into areas with deep indentations may also help prevent recurrence.
The treatment takes about 30 minutes. To achieve your ideal skin,A frequency of about 3 to 6 times per month is effectiveThat's right. In addition, at Yayoi Clinic, we have put in place measures to ensure our patients feel at ease, taking their comfort into consideration through skin cooling, anesthetic creams, and gentle touch.
Potenza

Potenza, which combines microneedles and high-frequency RF, is a cosmetic medical treatment that enables effective drug delivery to acne scars.
First, microneedles are inserted into the skin to deliver thermal energy directly to the dermis. ThatAs the skin attempts to repair damage, it produces collagen and elastin...will be performed. As a result, this treatment is expected to improve skin firmness and elasticity.
Its key feature is a unique drug delivery system that efficiently delivers active ingredients into the skin. We recommend “Macum,” a treatment that promotes collagen production and targets acne scars. Additionally, using the S25 tip can help reduce skin unevenness.
The treatment takes about 45 minutes for the entire face.A frequency of at least three times every 4 to 6 weeks is effectiveThat's right. Another key benefit is that you can apply a CICA mask after treatment to reduce redness during the downtime.
Isotretinoin

Unlike the treatments discussed so far, isotretinoin is an oral medication. It has been used in the United States for over 20 years and is considered effective for severe acne.
When taken orally, its bactericidal and anti-inflammatory effects against Propionibacterium acnes are expected to be effective even against acne that is difficult to treat. The treatment period is,Approximately 5 months to less than 1 yearThat's right. While you are taking this medication, we will monitor your progress about once a month.
At Yayoi Clinic, we generally recommend starting with treatment at a dermatology clinic for acne. However, for those struggling with acne that hasn’t improved even after dermatological treatment, our doctors will examine your skin condition and determine whether isotretinoin is appropriate for you. Please feel free to come in for a consultation.
