Does not contain the most effective ingredients for moisturization. The emollients (cyclopentasiloxane, hexyldecanol) can help soften the upper layer of the skin. Keep in mind though that this product lacks humectants that attract water. You might want to use a separate product with ingredients like hyaluronic acid or glycerin in addition (use before this product for the best results).

Product summary

"P20 - Sunfilter SPF 20" offers broad spectrum protection. It means that it protects from both UVA and UVB rays (you can remember UVB as "burning" sunlight - they cause sunburn. You can remember UVA rays as "aging" - they do not lead to sunburn, but they cause photodamage and contribute to early signs of skin aging and hyperpigmentation). On the negative side, the SPF of it is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.

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: uvinul a plus 5.00% - 7.50%, octinoxate 3.90% - 5.90% and octocrylene 8.60% - 12.90%.

Irritation risk

It contains some common irritants, including those without 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
