Skin resurfacing can improve the sun damage, reduce the density of wrinkles and improve uneven pigmentation and superficial scarring. Mechanical dermabrasion or dermaplaning can improve acne formed scarring. It uses fine abrasion or scalpel to remove the skin surface layers to a controlled depth. Chemical solutions or peels have different concentrations applied to remove the surface layer of skin. These then allow new skin to form that is tighter and smoother. Many lasers improve the damaged skin. Fractional and intense Pulse Light (IPL) lasers require several treatments with less downtime than the traditional CO2 and erbium lasers. With the CO2 lasers, the deeper layers of skin are addressed. There is flaking and crusting that resolves in 5-10 days. Skin is most likely pink or flush for several months.
