Product summary

We believe that "BIOTHERM - Waterlover Hydrating Sun Milk Eco-Conscious Tube" can provide reliable sun protection based on the ingredients listed. 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).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

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. Here are the exact UV filters in this sunscreen: tinosorb s 4.40% - 5.40%, avobenzone 2.10% - 2.60%, mexoryl xl 0.45% - 0.65%, octisalate 3.20% - 3.90% and uvinul t 1.70% - 2.00%.

Irritation risk

This product contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this sunscreen to be medium. For a detailed overview of all potential irritants: click here
