The scorching sun is getting stinging. No wonder, more and more are beginning to use cream with high SPF as a solution. However, is it true that high SPF creams are able to protect the skin more optimally?
SPF or Sun Protection Factor is an indicator of how well sunscreen can reflect ultraviolet light. That is, SPF is not a composition, but an indicator.
There are two types of ultraviolet rays that can harm the skin, namely ultraviolet A (UVA) and ultraviolet B (UVB). UVA rays can accelerate the signs of aging on the skin, such as wrinkles and black spots.
While UVB rays can make your skin burn. But overall, the high exposure of the skin to these two rays could potentially cause skin cancer.
SPF Skin Protector
Based on research published in the Journal of the American Medical Association Dermatology in 2015, more than 50% of study participants have the wrong perception of sunscreen. They thought that SPF 30 sunscreen had twice the protection function compared to SPF 15 sunscreen.
In fact, the protection between SPF 30 and 15 does not vary much. This is because the SPF 15 sunscreen can withstand UVB rays as much as 94%, SPF 30 by 97%, and SPF 45 by 98%.
When using sunscreen, you also need to reapply every 2 hours, after sweating, exposure to water or swimming.
In other words, it's useless to use an SPF 50 sunscreen at a high price if you do not reapply after some time.
Actually, using SPF 15 sunscreen alone is enough. However, if you tend to move outdoors, do not hesitate to use sunscreen with SPF 30.
Thus, the high SPF level is not a complete skin protection guarantee. The most important thing is how to use, as well as the activities you do.
