Hi. My wife has skin pigmentation on both her cheeks akin to melasma since 1.5 years. She is not taking any medication or contraceptives and her
thyroid levels are normal too. There pigmentation started 1.5 years ago a few weeks after a bleach treatment at a reputed beauty care centre. She has been using sunscreen and homeopathic treatment but it has not worked. Pigmentation disappeared temporarily a year ago but is back since last few months.
