We know that blue light exposure from the sun (in addition to UV light) contributes to #hyperpigmentation and #melasma in people with melanin-rich skin. Iron oxides (molecules that give products color/pigment) protect against blue light and are in tinted SPF and foundation! So if you can’t find a good spf shade match, use your foundation on top of your #sunscreen instead! #spf #bluelight #melasmatreatment #dermatologist #dermdoctor #dermatologia
