Which part of the body they're on. If they're not in visible places, why are you worried? If they're in intimate places...... um, I don't know.
I've heard of a countertubex cream that removed all sorts of scars and spots from the skin. If it doesn't work, I'd ask for any procedures at a dermatological center, but they'il be expensive. Look on someone's website. Drink plenty of water, minimum liter and a half, this will help the skin in general to clear, to similar color. I used to have some spots on the skin, since I started drinking 1.5-2 liters of water a day, this problem has healed. Also too much carbonated, sweet and battered, if you consume, kills the skin in the form of acne, spots and dark circles.
Peeling. Proven efficacy. There is a chemical (with trichloroacetic acid or retinol for the most effective for this purpose, but in sensitive skin they are not used). Another option is dermabrasion. In any case, it takes at least 3-4 procedures to notice a change and more if you want to completely clear the stains. It's a long process, consider a year. But it also depends on the color, if they are not very dark, it becomes faster. Go to an aesthetics clinic and they'il let you know there. I've done peeling, not for spots, spots, but for skin refreshment. And indeed, smoothes fine wrinkles and improves the look.
Mine left with Skinoren (azeelaic acid)
