As Farber puts it, "Your best friend for pigment changes is sunscreen. No matter the cause, sun exposure will exacerbate the contrast. I like mineral based sunscreens like EltaMD UV Clear."
"Retinol and retinoids like SkinBetter Overnight AlphaRet are often appropriate to even out skin tone, but discuss a regimen and in-office procedures with your dermatologist," says Farber.
Using an antioxidant-rich serum daily can also help boost and brighten your skin's appearance and help get rid of those marks.
