Hi. Thanks for posting your concern at HCM Pigmentation after hair remover cream is a common side effect. You can use a demelanising cream like the one containing kojic acid, Arbutin, Glycolic acid to lighten the pigmentation. You can use a cream containing Eflornithine hydrochloride to slow down the hair growth. It inhibits the hair growth cycle but effects are only as long as you use it. The best way to get red of unwanted hair permanently is to undergo laser hair reduction. You will be required to undergo 6-8 sessions for complete reduction. Thereafter you might need to take maintainance session once in an year or two. take care regards
