What are the treatment options for hyperpigmentation from Tretinoin around the inner thigh and bikini line? (Photos)

Thank you for your question. We have been very successful lightening the pigment and scar tissue in personal areas including areolas, bikini area, knees & elbows using the PicoSure laser with the FOCUS and / or Flat Lenses with a series of treatments. We would encourage you to find an experienced provider with excellent reviews that can competently handle this. We prefer the PicoSure's 755nm for pigment & scar correction in patients with darker skin. FOCUS lens treatments have the extra benefit of reducing any texture issues. PicoSure has almost no downtime. This is one of our go to treatments for patients older than 40 and worried about the signs of aging. This laser is safe for all skin types. We also send some hyperpigmentation patients home with prescription strength 4% Hydroquinone (HQ). Do not buy it over the counter or off the internet. Laws vary by state. In Texas, physicians can prescribe and dispense in office. Start with sunscreen every day! Once you have treated your hyperpigmentation to your satisfaction, you will probably need a follow treatment every 6 to 12 months depending your level of re-pigmentation. Best of luck.

Thank you for your question and photographs. It's difficult to evaluate your skin through this type of forum, but from what I can see, it looks like you have post-inflammatory hyperpigmentation. There are various treatments that are effective such as topical prescriptions, laser tx, etc. I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss appropriate treatment options. Take care and good luck.
