I had laser hair removal on my upper lip which left me with darker skin. Everytime I get in the sunlight my mustache area will get much darker than the rest of my face. Very embarassing!! I have medium dark skin and very dark brown hair and eyes. I had around 15 treatments and the hair still grows. The doctor kept increasing the number on the laser b/c my hair was so resistant. One treatment left me burned with scaps and I think that's what caused the skin sensitivity to sun. SO PLEASE MAKE SURE THEY DO NOT TURN UP THE NUMBER TOO HIGH AND BURN YOUR SKIN. BE CAREFUL DIECTLY AFTER TREATMENT AND PROTECT FROM THE SUN. I had my honeymoon during this time and spent one solid week in the sun unprotected b/c I didn't know better.
