Which sunscreen is best for aging skin?
For aging skin, the best sunscreen is SPF 50 with PA++++, in a hydrating cream or lotion formula. These ratings ensure protection against both UVB (the burning ray) and UVA (the ageing ray). A sunscreen that also includes moisturising ingredients is ideal since mature skin tends to be drier and benefits from combined hydration and protection.
UVA is the wavelength primarily responsible for breaking down collagen and causing the changes associated with photoaging, including fine lines, loss of firmness, and uneven skin tone. PA++++ is the highest available rating for UVA protection and indicates a product has passed rigorous testing. For mature skin, avoid formulas that are overly matte or alcohol-heavy, as these can emphasise dry patches. A cream sunscreen worn daily and reapplied when spending time outdoors is the single most impactful skin-protective step available to an older adult.
