Age spots and dots can be due to different skin conditions including age warts – called dermatosis papulosis nigra or DPN, sun spots, freckles, actinic keratosis and in rare cases skin cancers. Most cases are harmless, however if in doubt, a dermatologist can give you the best advice as to how to remove pigmentation.
Some forms of pigmentation such as melasma or hormonal pigmentation need special creams and low powered lasers, whilst freckles can be removed with simple IPL or BBL.
If a spot is raised, I like using a combination of ablative lasers including CO2 lasers, and erbium lasers with a curette. IPL will not be effective for raised skin pigmentation. TCA peels can be effective, however lasers are more accurate.
Fraxel fractional laser resurfacing can be useful, however I only use this as a general skin rejuvenation procedure, or for treating solar keratosis, or actinic keratosis. Low level Fraxel known as Clear and Brilliant can also improve some forms of pigmentation. Fraxel can be used to treat spots and dots on the face, neck, chest, and arms. I often use this in conjunction with IPL a procedure I call Pusle Fraxel Fractional Laser Resurfacing.
