Hello Jol
Thank you for your question. There are may ways to treat post inflammatory hyperpigmentation (PIH) marks as a result of acne. You can use topical creams, chemical peels or lasers. Depending on the severity of the PIH, usually a combination treatment will give you the best result.
Depending on your skin type, I would generally use a milder peel such as Glycolic Acid peel 30% to 50% at the start. It is well tolerated, safe and has close to no downtime. Other peels such as Jessners/ TCA/ Salicylic Acid can be used as well. I will usually prime the skin before chemical peel with topical retinoids such as differin or retin-A. This will help to exfoliate your skin to get a better and more even result from the peel.
Chemical peels should be performed by a certified and trained doctor as there can be potential risks from the treatment such as skin infection/ scarring/ PIH etc. Speak to a doctor to find out more!
Regards,
