However, sunscreen is not necessarily enough to fully protect the skin. You should wear sun-protective clothing and stay in a cool place to avoid going outdoors during peak hours.

SPF in sunscreen what effect
SPF is the acronym for sun protection factor. It has the ability to protect the skin against UVB rays. The SPF index in sunscreen tells you how many minutes of protection time the skin will be protected when applying the cream.
You can understand it simply as follows:
- If your skin is outdoors, if you do not apply sunscreen for 10 minutes, your skin will be exposed to ultraviolet radiation that will damage your skin.
- If you apply sunscreen to protect your skin for 150 minutes outdoors, the SPF index is 15 (150/10). With this index, the ability to protect the skin from UVB is about 94%.
- Skin protection against UVB rays increases by 97% with SPF 30 and increases by 98% with SPF 50 or 50+.
The difference between SPF 15 and SPF 30 or 50 or higher is only a 3 to 4 percent difference. Dermatologists agree that to protect the skin from UVB rays, only SPF30 is enough.
