Laser FX Bright Serum fades dark spots and discoloration for a more even, uniform, and brighter skintone. It prevents future spots from resurfacing, and helps fight photo aging including infrared-induced aging and thermal aging. This serum is inspired by laser procedures performed at Dr. Brandt"s medical office. For optimum results, Dr. Brandt recommends to use daily UV protection with SPF 30 or higher, such as BB Flexitone, and avoid prolonged times of sun exposure.
