The techniques for treating acne scars are constantly evolving, with one of the most important methods being subcision. The main purpose of this procedure is to remove the fibrous tissue beneath the scars, realign it, and promote collagen production. With advancements in technology, today’s subcision techniques can be categorized into various methods. The most basic approach involves the use of a needle, but this requires a physician to possess good skills to avoid the formation of new scars.
With technological progress, we have adopted several innovative techniques that significantly improve the effectiveness of subcision. For example, we now use catheter technology to disconnect fibrous tissue and inject long-lasting hyaluronic acid or medications for enduring improvement.
In addition, the introduction of picosecond lasers in modern medicine can cause tearing and cavitation in the dermis. Although some patients may feel fear upon their first experience and question the safety of the procedure, this method, when precisely performed, can yield excellent treatment results. The bleeding response during the recovery process stimulates growth factors, which can enhance therapeutic effects.
Besides picosecond lasers, deeper laser treatments such as fractional carbon dioxide lasers are also continuously developing. When acne scars are thicker, fractional carbon dioxide lasers can be employed for deeper processing, effectively addressing rolling scars and atrophic scars, while also promoting collagen regeneration.
In recent years, multi-level scar treatment techniques like Morpheus8 have become an indispensable part of therapy, allowing for deeper healing of severe scar tissue and further enhancing aesthetic outcomes. Traditional therapies when applied alone often lack efficiency for general scars, whereas new treatment methods can overcome this challenge.
TCA peels can promote collagen proliferation, but for some patients, the risk of post-inflammatory hyperpigmentation is too high, leading them to feel anxious after treatment. Therefore, seeking more effective solutions, especially for ice pick and boxcar acne scars, becomes particularly important.
Treating acne scars is a complex task that requires comprehensive medical knowledge and skills to deliver the best quality treatment outcomes for patients. If needed, it is advisable to consult a doctor first.
