My knee is dark and I want to lighten it. Will laser treatment help or anything else will help?

Having only dark knees, elbows, knuckles etc need proper evaluation before going for any procedure. If there are no internal issues, deep peels, fractional ablative and pigment removal lasers can give excellent results to improve pigmentation.be sure to get evaluated by a certified dermatologist before starting any procedureAll the best

Hi , Thank you for sharing your question. Laser or skin lightening chemical peels are good options to improve skin tone. Remember to use skin brightening agents to maintain the results. Meet a board certified expert.
