Sunscreen which needs no introduction in today's world of skincare, helps us to protect our skin from the harmful UV rays from the sun. Sunscreen does its work by completely absorbing, reflecting, and scattering the harmful rays of the sun. They contain active ingredients such as organic and inorganic filters.
These organic filters help to protect our skin from the sun by quickly absorbing the UV radiation and converting it into heat, but inorganic filters like zinc oxide and titanium oxide help by blocking the UV radiation from entering the skin. We can also see, that sunscreens are available in different forms such as lotions, creams gels, etc. Also, the sunscreens vary in different levels of Sun Protection Factor(SPF).
What is SPF?
SPF is a Sun Protection Factor, it is a degree of protection of our skin against the sun's UVB rays that are the main reasons for sunburn and skin cancer. The SPF also contains the number or the levels of protection against the sun's rays(UVB rays).
Here's how it works:
| SPF 15 protects around 93% from UVB beams. |  |
| SPF 30 blocks around 97% of UVB beams. | |
| SPF 50 protects approximately 98% of UVB beams. |
The higher the SPF number, the more prominent the level of security against UVB beams. But you need to be sure that sunscreen alone can not give you 100% protection from the sun. SPF measures against the UVB beams so select a broad-spectrum sunscreen for optimum sun protection. It's prescribed to utilize sunscreen with at the slightest SPF of 30 and to apply it liberally and regularly, particularly when spending time outside, reapplying every two hours or more habitually if sweating heavily.
What type of sunscreen you should use?
In the skincare industry, there are several options available for sunscreens nowadays, you should select a sunscreen that is light and contains essential minerals. Make sure you use sunscreen 15 SPF or 30 SPF on over sunny days.

Furthermore, you ought to too apply sunscreen to the rest of your body that will be uncovered.
