I have tried many different remedies like hydroquinone, chemical peels, microdermabrasion, azelaic acid, arbutin, vit C, MSM pills, niacinamide, pycnogenol pills, mulberry and bearberry extracts etc.
Nothing seems to remove the dark spots completely.
The dark spots on my forhead fade
fast but the ones on my chin and cheeks can last for 2 years. I get occasional pimples but the dark spots lasts so long so when the old ones have faded , they become replaced with new dark spots.
