How does sunscreen work?

As we approach the hot summer months many of us are outdoors enjoying the warm and sunny days by the pool, beach or other spots. It is essential that we apply the best sunscreen when outdoors during these warm and sunny days to protect our skin. As has been mentioned by us before in our other blogs using sunscreen is essential for protections against UV light.

But as we apply the sunscreen on our skin some of us may be wondering how it actually works and protects us. Essentially all sunscreens weather in the form of spray, lotion, wax or gel are composed of mix ingredients.

Sunlight reaches earth in a number of ways which include invisible and visible rays. Many of these rays that reach the earth are composed of ultraviolet (UV) light. What happens when these UV rays, impact on our skin cells is that they disarrange the normal procedure our body control the appearance of our skin and the growth rate of our skin cells.

Sunscreen actually uses a number of chemical particles to block UV lights. These physical particles are numerous and include titanium dioxide and zinc oxide which helps your skin to reflect UV light. It actually works the same way as white paint reflects light and that is why white is the primary colour used on houses in warm and sunny locations.

But to even protect your skin further at the same time that sunscreen reflects UV lights from your skin, other compound ingredients respond to UV radiation before it penetrates your skin. These compound ingredients help to absorb the UV light and let it out as heat. This combination of protection sunscreen offers which includes both blocking and absorbing the UV lights is essential in how our skins are protected by using it.

The importance of SPF in sunscreen also needs to be looked at when talking about how sunscreen works. Many of us think the SPF shows the power of the sunscreen we are using. But The SPF rate actually is about how much longer it takes UVB rays to make our skin red in compare to not using sunscreen. The UVB rays are the most harmful rays that can damage the skin. So, a SPF of 20 actually means it will take 20 times longer for our skin to be burned by UVB rays in compare to without using sunscreen.

In general, it is recommended to use sunscreens that have a SPF of 15 and 50.

CHOLLEY offers a number of sunscreen creams you can choose from to protect yourself. When using a sunscreen with a SPF of 15 you are protected against 93% of UVB rates and a sunscreen with SPF of 30 protects against 97% of rays based on a research done by Mayo clinic.
