Because older skin doesn't heal as quickly, you're more susceptible to acne scarring, says NYC dermatologist Dr. Dennis Gross. While over-the-counter brighteners improve irregularities, consult your derm if you have severe pigmentation issues - particularly if you're on birth control, which can exacerbate the situation. Laser treatments, like Fraxel, reduce spots and scars, but there's downtime. A new approach called Portrait Plasma (approximately $3000 for three treatments) uses plasma energy (which painlessly deep-heats the skin's tissue) to treat scars and promote new collagen growth.
DIY: Make sure your spot treatment also soothes the surrounding area. Peter Thomas Roth Acne Spot and Area Treatment is rich in sulfur and has 20 percent aloe. Vichy NormaDerm Night is a night cream that clarifies skin tone and won't clog pores.
