This product can help soften the skin and reduce its moisture loss with emollients and occlusives: dimethicone, stearic acid.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Product summary

We assess that "Coppertone - Water Babies Sunscreen Lotion SPF 50" can provide reliable sun protection based on the ingredient list. 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).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. The UV filters in this sunscreen are: oxybenzone 22.00% - 33.00%, avobenzone 3.00% (declared), octisalate 5.00% (declared), homosalate 13.00% (declared) and octocrylene 7.00% (declared).

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of it to be medium. For a detailed overview of all potential irritants: click here
