Choose a sunscreen that is lightweight and easy to spread—liquid formulas are best—so it won’t clog your pores;
It should be colorless, fragrance-free, and non-comedogenic (no powder). Colored or powdery sunscreens require makeup removal, and sweat can easily cause a "smeared" look, which is very inconvenient in the wild;
The SPF should be high—generally SPF 20–25 at low altitudes, and SPF 30+ at high altitudes.
When using it, pay attention to the following:
Reapply as needed, depending on sun intensity. In high-altitude, sunny areas, apply every half hour. Before reapplying, blot away facial oil;
Use a small container to reduce weight and make it easy to carry in your pocket;
Also apply a lip balm with SPF;
Pay attention to protecting your neck and ears. In high-altitude areas with strong sunlight, wear a sun hat and sunglasses in addition to sunscreen.
Cleaning sunscreen:
Many sunscreens have waterproof properties, so they can’t be washed off with water alone. You’ll need to use a makeup remover—cleansing wipes work well;
There’s also a type of facial cleanser specifically designed for outdoor sports. This kind doesn’t need to be rinsed off—you can apply it to your face and then wipe it off with a tissue. It cleans effectively too.
