Product summary
The ingredient list suggests that this product can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (not all sunscreens with SPF ratings give UVA protection. UVA rays do not cause sunburn, but still damage our skin and lead to early aging).
Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
