A. You can! But the results depend on what kind of skin damage you have. If the spot is raised, with a flat surface and even brown color, that's a keratosis. These stubborn growths are trickier to treat. I recommend two dermatologist-adminstered procedures:
In microdermabrasion, tiny particles are blasted on the skin to remove its outer layer. With a Fraxel laser treatment, a laser is used to create tiny penetrations in the skin, stimulating new collagen growth.
But if your spot has irregular borders and uneven color, try over-the-counter treatments. Dab a little lemon juice on the area daily to lighten dark patches, then use an exfoliating scrub twice a week to remove the dead skin cells. The key is sticking with this regimen: It'll take about six weeks to notice any change.
