I have also had a pigmentation mark on my cheek for approx 10 years. Little larger than my thumbnail. Because it is in such a prominent area I have tried many so called fading potions and lotions! ie. Eucerin, Murad, Ordinary, many others, tumeric, lemon juice, bicarbinate of soda., bleach - from 3% to 12%. Had IPL - 3 sessions (little fading). Over counter freeze spray. Just used Bazuka last night and had to remove after a few mins because of stinging. Don't know if to try again tonight? Any advice welcome. Cannot afford Dermatologist.
