Product summary
We believe that "Mustela - Solaire SPF50+ Sun Stick" can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because 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.
