When should you reapply sunscreen?
Extended exposure to UV rays can lead to an increased risk of photoaging, photodermatoses, pigment spots and skin cancers. Therefore, it is crucial to protect your skin from the sun's UV rays, particularly UVA rays. The daily and regular application of sunscreen products containing sun filters is one of the effective methods to block as much UVA and UVB rays as possible, thereby protecting the skin from the harmful effects of the sun.
Selecting the right sun protection factor alone is not sufficient for adequate sun protection, it is also recommended to reapply the sunscreen at least every two hours for outdoor activities (beach, skiing, etc...), immediately after swimming or excessive sweating. For individuals working indoors, it is not necessary to reapply sunscreen, provided that the recommended amount applied in the morning (2 mg/cm2) has been adhered to.
But why is this so? For a sunscreen to work, it must form a uniform film on the skin. However, after a certain period, this protective film can "move" or interact with the skin's natural lipid layer. Sweat, water (during swimming)... can also alter it. Furthermore, under the effect of sunlight, certain sun filters (like avobenzone, etc...) contained in the sunscreen tend to degrade (photo-stability) and their effectiveness is reduced, leading to an alteration of the product's protective properties.
3 ways to reapply sunscreen when wearing makeup.
First recommendation: Apply your sunscreen with a high sun protection factor (2 mg/cm2) before applying makeup. Additional tip : Use a makeup setting spray to both set your makeup and also secure your sun protection.
The ideal scenario would be to remove your makeup and start from scratch. To simplify, here are different ways to apply sunscreen over makeup in order to combine sun protection and makeup under the sun, all without ruining your beauty routine and without letting UV rays damage your skin:
Application using a makeup sponge: To successfully and sufficiently apply sunscreen after makeup, you can use a makeup sponge. To do this, take some sunscreen with the makeup sponge, then apply it by gently dabbing it onto the skin;
Investing in a Sunscreen Mist: Another option for UV protection while wearing makeup is to spray your entire face with a sunscreen mist in circular motions, while keeping your eyes and mouth closed. Easy to use, it has the advantage of being quite convenient for reapplications at your leisure throughout the day, in addition to hydrating and refreshing the skin, without damaging the makeup. However, be careful not to inhale it during application;
Choosing makeup with a sun protection factor: BB cream, tinted cream, foundation... some complexion makeup products are equipped with sun filters in their composition. You can supplement this with the use of a sun powder. In addition to mattifying the skin, it also provides UV protection. While convenient, this method will provide negligible sun protection, as the applied quantity is insufficient.
Despite all these solutions, the best protection remains to avoid prolonged exposure to the sun, to wear a hat, and to stay in the shade as much as possible.
