Our skin needs sunscreen. It’s not a point of want or requirement; we need it. With global warming on the rise, depletion of ozone layer, our exposure to UV rays is no joke. Various ailment ranging from sunburns to skin cancer are just sunrays away.
You might ask what is the difference or functions of both. Quite simple, Mineral ingredients settles on the skin and creates a shield that deflects UV rays, while chemical ingredients allows UV light in to the skin and create a chemical reaction in which UV light is converted to heat, and the heat dissipates from the skin.
Another calculation differs from skin to skin. If it takes your skin 15 minutes to get sunburns then an SPF 30 would make sure that it takes you 30 times more time to burn in the sun, which in this case would be 5 hours, which is why it is necessary to reapply sunscreen on an average of 2 hours.
UV rays are present everywhere, even the light emitting from your phone and laptop screens can be harmful. Two types of UV rays you’d read a lot about are UVA and UVB – the third and the most harmful are UVC rays, fortunately, they don’t reach the surface of the earth.
UVA rays gets absorbed into the skin and are majorly the ones responsible for long lasting skin-ailments. 95% of Sun’s UVA reaches the surface of the earth and they can penetrate through windows and glass, rendering indoors unsafe.
UV rays are always around us so it’s necessary that sunshield becomes a staple in your AM routine, when you are in the house or outside. It can be avoided during PM hours because Sunscreen can clog pores. So make sure you double cleanse.
