I recently finished pouring through the last 2 years of acne scar research and have updated the scars page. It’s an evolving field. Here’s what I found:
Lasers are becoming more and more the go-to treatment for acne scarring. Fractional lasers, which treat only a fraction of the skin at once, are also becoming more popular for their ability to reduce side effects while still producing results.
Scientists are incorporating radiofrequency devices along with lasers and data is promising, while not earthshattering, that radiofrequency could help a bit.
Scar revision specialists have treated scars with fat injections for years with lots of success. However, recently, they are trying what they call autologous fibroblasts, which are cultured connective tissue cells from the person’s own body. This is also showing lots of promise.
Despite the advances, a person embarking on scar revision should not expect miracles, but should instead expect improvement. As always, data is showing that a combination of treatments (i.e. laser combined with subcision and augmentation) produces the best outcomes especially in more severe scarring. According to an article in the journal Dermatologic Surgery, “Severe grades of scarring often require a combination of filling agents for volume deficit, injectable agents for hypertrophic disease, neurotoxins to effect movement, and fractionated and ablative resurfacing for surface changes.”
Lastly, there appears to be vast confusion amongst dermatologists in the classification of acne scars. This highlights the need to carefully select a scar revision expert who is dedicated to and experienced in this specific area of surgery. If you decide to embark upon acne scar revision, do your homework and make sure you go with someone who specializes in acne scars.
