How can we not talk about sunscreens in summer??? 🙂
Here is a series of posts coming your way to bust the general myths around sunscreens & their usage.
Myth #1 – Natural sunscreens are not as effective as conventional chemical sunscreens.
A sunscreen with SPF 30 can prevent around 97% of UVB rays from penetrating the skin.
This is either done by absorbing (as with a sunscreen) or by reflecting (as with a sunblock) UVB radiation.

Researchers mention that chemical UV absorbers break down & are not stable UV reflectors.
Studies also show that chemicals like oxybenzone break down quickly, that they can release free radicals that damage the skin – than if you wore no sunscreen at all.
While chemical sunscreens offer higher SPF ratings, their lack of stability can create as much damage as the sun itself.
Natural sunscreens containing non-nano zinc oxide are much more effective in the long run, researchers say, because they are much more stable.
