MooGoo Clear Zinc Sunscreen is formulated with zinc because it's naturally derived, even if it makes the cream a bit thicker and a little harder to apply. Zinc oxide acts like a reflective umbrella on the skin, reflecting UV rays away. It's suitable for all ages, from babies to adults, and even newborns, as well as all skin types, even the most sensitive. This sunscreen is ideal for people who are sensitive to sunscreens with UV filters and want a zinc-based sunscreen that's not greasy. It's also for people who like to know what's in their sunscreen. Key features include a natural, water-resistant, zinc-based SPF 40 sunscreen that rubs in clear. The active ingredient is zinc oxide at 24.96% w/w, with no chemical UV filters. It's moisturising and gentle enough to reapply throughout the day as required. Apply generously to exposed skin 15 to 20 minutes before going outside.
