How can IPL work in acne?
Selected wavelengths can affect bacterial porphyrins, the inflammatory response, and superficial vascular components. Some protocols have been combined with photodynamic therapy or chemical peels.
Scientific data
A 2020 meta-analysis reported that IPL showed a signal of clinical efficacy in acne vulgaris. In a 2022 meta-analysis, the combination of AHA with IPL showed higher overall response rates compared to AHA or IPL alone. However, there is significant heterogeneity among protocols.
Is it the same procedure for acne scars?
No. Active inflammatory acne and ice-pick, boxcar, or rolling scars are different treatment targets. For acne scars, fractional laser, RF microneedling, subcision, or combined approaches may be more appropriate.
Safety
Parameters are selected carefully in active tan, photosensitizing medications, and dark phototypes. Acne treatment is evaluated not as a replacement for dermatological care, but as an adjunct method in appropriate patients.
Our approach at our Bodrum clinic
First, we differentiate active inflammation, comedones, hormonal distribution, and scar components. We select IPL/BBL only if there is an appropriate target, combining it with medical acne treatments or peels when necessary.
