Is there anything I can use to prevent melasma from coming back during 1 month rest of hydroquinone 8% on my face?

You must use diligent sun protection and speak to your dermatologist to see if you are a candidate for other fading ingredients such as tretinoin or kojic acid preparations.

the Picosure laser is the most advanced way to treat melasma. however, it will often come back unless . you use a powerful sunscreen. a good plastic surgeon or dermatologist's office will have a number of excellent skin creams to help with the treatment but the picolaser will do the best job of treating and improving your entire face (and neck and decollete and hands) but it is not your only option. good luckdavid berman md
