How long does spf30 protect you from the sun? In summer, you need a product with better sun protection.

Summer is here, and all the fairies have started buying sunscreen. Many fairies have bought spf30. First of all, you need to know how long the sp30 sunscreen can last. You will know after reading this.

How long does spf30 protect against the sun?

SPF30 means that without sweating or other external influences, it can block ultraviolet rays for 15*30=450 minutes, which is equivalent to more than 7 hours. But in fact, SPF30 sunscreen cannot protect the face for such a long time, because it is easy to sweat in summer and skin types are different, so it needs to be reapplied every three or four hours.

How much SPF sunscreen do I need in summer?

Students and office workers: SPF30 sunscreen (PA++, PA+++)

Outdoor athletes, beachgoers, and travelers: SPF50 sunscreen (PA+++, PA++++)

Note: Even if it is SPF50 sunscreen, it is best to apply it every two or three hours. Because the sun protection ability of sunscreen is greatly affected by external factors. In addition, if you do not use enough sunscreen or apply it unevenly, the sun protection ability indicated by the sun protection index will not be achieved. Therefore, you must reapply it in time when going out.

Sunscreen product recommendations

benefique sunscreen ★★★★★: [Deyi R] A brand under Shiseido, with a patented black technology of infrared rays. Sunlight contains not only ultraviolet rays but also infrared rays, which can cause allergic reactions to the skin. General sunscreen products are targeted at ultraviolet rays, but this one from Bilifei not only prevents ultraviolet rays from damaging the skin, but also effectively prevents infrared rays. This sunscreen is very suitable for facial use. The large capacity of 50ML is also super great. It forms a film quickly after applying it on the face and it won’t cause oiliness when used in the summer.

Biore Sunscreen ★★★★: An affordable sunscreen, so it is perfect for applying on the body. You won’t feel too bad about it. It’s better than using Anessa on the body. Because it is a whitening product, it feels like it brightens the skin tone a little bit when applied. It is especially suitable for applying to the neck when applying makeup, so that the colors of the face and neck will appear to be perfectly connected.

Anessa Sunscreen Spray ★★★: I bought the gold bottle. Why? Because I’ve never used the silver bottle or the white bottle, hahaha. This sunscreen spray is simple and convenient, and is suitable for daily use when you don't have much time to go out and are too lazy to carefully apply sunscreen all over your body. But to be honest, I just did it for convenience. I personally don’t like the smell of Anessa.

Shiseido Blue Fat Sunscreen ★★★: When I bought this product, I hadn't come across Bilifil yet, but after using it a few times, I gave it up and used it for body sunscreen. To be honest, I personally feel it's a bit greasy, so I don't think it's suitable for applying on the face. This one has better water resistance, so I used this bottle when I went to Thailand several times and it worked well. Remember to apply sunscreen frequently when you go to the beach, especially if you are going snorkeling. I once applied it only once because I was too lazy to do so and happily went into the sea. But when I got ashore, I died immediately because I was too obviously sunburned.
