Mineral or chemical? SPF 30 or 50? A dermatologist answers the questions we get every day.
Sunscreen is the single most effective anti-ageing product, and the one most often skipped.
Why mineral
Zinc oxide protects against both UVA and UVB and is gentle on sensitive skin. The catch has always been the white cast, which is why we tint our Sun Veil for Indian skin tones.
How much
Two finger-lengths for face and neck. Reapply every two to three hours when you're outdoors.
