SPF 50 Sunscreen 25% Zinc oxide

SPF 50 sunscreen

Z-Block SPF 50 gel is listed as a water-based sunscreen. The category title refers to 25% zinc oxide, but the product name does not identify its UV filters or confirm the zinc oxide content. SPF describes protection against UVB-related sunburn under test conditions; it does not, by itself, tell you the level of UVA protection. Check the product label for its ingredients, UVA information, water-resistance claims and directions before relying on it. The gel format may suit adults who prefer a water-based sunscreen.

Sunscreen is one part of sun protection, alongside shade and clothing. Apply and reapply it according to the label, particularly after swimming, sweating or towelling. Keep the gel away from the eyes and stop use if a reaction occurs. If you use tretinoin, ask your prescriber about sun protection. Tretinoin is prescription-only in the UK and can increase skin sensitivity to sunlight.
