How much sunscreen do I need and when do I reapply?
Lee Ji-ho
A small dab like the day cream is usually not enough. Two generous strips of cream along the index and middle fingers can be a rough everyday aid for the face. This is not an exact dosage: finger length, tube opening and face size vary. The neck, ears and other uncovered areas need additional protection. Distribute the cream evenly and follow the quantities indicated on your package.
For outdoor use, choose at least SPF 30 with protection against UVA and UVB radiation. Apply cream before you go out and reapply your protection about every two hours outside and after swimming, sweating heavily or drying off. When it comes to water and sports, you need an appropriately waterproof product; Even then, cream is applied. Shade and clothing are part of it.
An example of sun protection in everyday life is the SKIN1004 Hyalu-Cica Water-Fit Sun Serum SPF50+ . The key thing with any product is that you apply enough of it. Reapplying the cream maintains the protection, but does not extend the possible time spent in the sun.
