The Sun & Your Skin

Hello lovelies, hope all is well. Today I wanted to do a post all about sun and suncare. Sun care is so important, not just for beauty but for health too. The suns harmful UV Rays can cause cancer and no one wants that; wrinkles, dark spots and premature aging aren’t very attractive either. First let’s talk about the Sun itself and it’s UV Rays. There’s 3 different types of UV Rays, and they each act differently and have different numbers on the broad spectrum.

UVC: shortest wavelength (100mm) usually don’t penetrate the earths ozone layer.

UVB: longer wavelength (290mm) that reaches the skins surface and can cause surface tanning, burning and signs of aging.

UVA: longest wavelength (320mm) can penetrate deep into the skin surface, releasing free radicals and causing DNA changes that can result in skin cancer.

So now how do we protect ourselves from these harmful Rays? Sunscreen of course, but how do you know which sunscreen to choose? There’s 2 types Physical(mineral) and Chemical sunscreen. What does that mean? Well let’s take a look…

Chemical Sunscreen: the main ingredient is avobenzone. They absorb the suns UVB and UVA Rays, along with (sometimes) containing harmful chemicals. Chemical sunscreen degraded when exposed to UV Rays. Usually require at least a 20-minute wait before ingredients become effective.

Physical/Mineral Sunscreen: ingredients include zinc oxide and titanium dioxide. Physicals reflect the suns UVB and UVA rays. So instead of absorbing them into the skin like Chemical, they reflect; also while wearing they do not degrade when exposed to the UV Rays, and they’re immediately effective from the moment you apply, rather than having to wait.

The different ingredients int both sunscreens of course do different things, Zinc Oxide is something you ALWAYS WANT, it’s the only active sunscreen ingredient that provides protection from both UVB and UVA (full broad spectrum). It works by creating a physical layer atop the skin rather than being absorbed into the skin then bloodstream.

SPF: Sun Protection factor; the average light-skinned person can stay in the sun with no sun protection for 15 minutes before burning. SPF is a multiple of 15, to determine how long one can last in the sun with sunscreen. You still need to reapply every 2 hours, especially if you’re sweating or in the water.

SPF15 x 15 minutes= 225 minutes SPF15 Blocks 93% of UVB Rays

SPF30 x 15 minutes= 450 minutes SPF30 Blocks 97% of UVB Rays

SPF50 x 50 minutes= 750 minutes SPF50 Blocks 98% of UVB Rays

Last but not least a fun little handy SPF Selection Guide…
