There are constant debates on how to use sunscreen and whether it’s healthy for our skin. Well, healthy or not, we have to use them. Without them, we would get sunburns and develop some serious health issues. They protect us from UVA and UVB rays, but some of the ingredients can be harmful. The best sunscreens are the ones that use physical protection.
In cheap sunscreens, the protection part is done by chemicals. They are cheaper and easier to produce. And they can, and will, in the long run, be harmful to your skin. We tolerate them because the alternative is getting massive sunburns that can lead to skin disease.
