#GLUGirl Guide to SPF & Essential Skin
(Light Blocking) Protection

There’s nothing that beats feeling the warmth of the sun on our skin or a lazy Saturday just watching Netflix on our phones or computers. And it’s summertime, so there’s room for both. 

But there’s more to it than just the relaxation benefits - lots of things emit light that’s potentially bad for your skin - think computers, phones AND the sun.

With this in mind, we have created a little guide to walk you through what you need to know to live your best summer and beyond. 


A little bit of science, shall we? There are 3 forms of UV rays: 

UVC rays: thank Mother Nature for this one, the ozone layer blocks out this light form.

UVB rays: 90% of these rays never reach us; the ozone filters them out too. But, they are still harmful. These suckers are the ones that cause sunburn.

UVA rays: when talking UVA, they are the least harmful but that doesn’t mean they can’t do damage. High sun exposure can lead to harmful skin conditions like skin cancer and advanced signs of aging, plus they penetrate the skin the deepest of all of the UV rays. 

Now using what we’ve learned, let’s break down a few skin/sun myths

  1. A tan is actually the skin’s defense mechanism against getting too much sun
  2. You can still get sunburn on a cloudy day. Clouds do not filter out UV rays, they actually break right through. 
  3. Being tan does not protect you from further sunburn 

It’s important to stay protected from the sun’s harmful rays, and thankfully we have our trusty UV index! 

The UV index ranges from 1-11+, and the higher it is, the faster you can get burned or see damaging effects from the sun. Even though it’s important to wear sunscreen all the time (yes- even when it’s cloudy), sun protection is even more important when the UV index is between 6 to 11+. 

So, when headed outside, apply our Screen Time 30 SPF sunscreen, reapply throughout the day and tell the sun to bring it on! 


What is it and why care? ? Blue Light is a high-energy light that is emitted from common household tech, like your phones, computers, tvs and lightbulbs. 

There are some pros and cons to blue light. 

Pros, yes, it boosts alertness and elevates mood, but may be the reason you scroll on your phone for two hours when you’re trying to sleep. 

Cons, and we’ve all fallen victim to them, it can keep you from sleeping, negatively impact your eyesight, and damage your skin. Not nice. . .

Since blue light can impact your skin just like those ultraviolet rays we have a solution for you: BLU Light Special protective serum

This serum is worn under sunscreen and makeup. And it has a superpower - marine bio-ferment that inhibits those nasty blue-light rays.  PLUS...added bonus...it’s a vitamin C serum that can help promote healthy skin cell turnover and lighten acne or dark spots for your glow-up from within.

In this new digital age with screens close to our eyes and faces, it’s very important to protect your skin from blue light just like you do from the sun. Consider adding the serum to your routine and picking up a pair of blue light glasses (we have those too!) They’ll keep you from eye strain and headaches plus they're just ugly enough to be cool.

Whether it’s taking in rays on the beach, or taking them in during class, we want you to be protected and know how to take care of your skin. Less than 50% of women wear sunscreen on a regular basis -- it’s time to change that! 

From GLU to YOU, it’s time for hot-sun-protected-girl summer. Let’s get outside.
