"UV rays affect all skin types, including skin of colour, all year round causing inflammation, worsening hyperpigmentation, and inducing DNA damage to skin cells that can lead to skin cancers. It's essential to use sunscreen if you're prone to hyperpigmentation like me. For this, I like the ISDIN Eryfotona Actinica Zinc Oxide and 100% Mineral Sunscreen Broad Spectrum SPF 50+ ($55). It's a non-greasy, light-weight sunscreen, perfect for the summer. It that does not leave a whitish cast and repairs DNA damage already done to skin."
