Quantum Blue

Fatskn | Local Supplier | 85 ml 

Quantum Blue is made with USP-grade methylene blue that acts as an electron donor and photosensitizer in skin cells. This helps you make the most of your time in the sun during the day and mitigate the stress of blue light at night. 

Depending on the season, there are a few different ways to use Quantum Blue:

  • with a red light therapy device 
  • as protection indoors against unopposed blue light 
  • to maximize the benefits from your time in the sun 

Perfect for anyone who:

  • Spends time in the sun
  • Wants to maximize red light therapy 
  • Works on a computer screen
  • Turns lights on after dark

It’s the ultimate “get your light right” skincare that works to:

  • actively repair cellular damage
  • strengthen defenses against oxidative stress
  • diminish and reverse physical signs of aging 
  • reduce inflammation and redness
  • increase cell regeneration and fullness
  • hydrate and soften skin
  • boost natural collagen synthesis

DISCLAIMER:

Methylene blue is not recommended for pregnant/breastfeeding women, anyone taking SSRIs, or those who are allergic to MB. This is a powerful therapeutic compound that should be wielded as such. Self-experimentation is key to finding what works for you and your biology. 

Ingredients:

  • Organic unrefined cold-pressed jojoba seed oil (a monosaturated cold-pressed oil, not to be confused with the OTHER seed oils)
  • Grassfed and grassfinished suet tallow
  • Filtered yellow Alberta beeswax
  • MB (USP grade)– a tincture with alcohol and purified water
  • Vanilla oleoresin

How to use:

Shake and pump onto freshly exfoliated skin and blend before heading into the sun or using your red-light therapy device to enhance metabolic benefits and protect against oxidation. Working late or watching a movie? Apply to exposed areas to neutralize the negative impacts of artificial blue light. Can also be applied after a day outside to minimize damage and encourage skin cell recovery.

Quantum Blue is not meant to replace sunscreen. It's meant to change the way you interact with the sun. Instead of a blocking the benefits of the sun — it's a tool to help optimize your time in the sun.

How to practice mindful sun exposure without sunscreen:

  • nourish skin with antioxidant-rich saturated fats
  • limit PUFAs in your food and skincare
  • consume whole foods high in antioxidants
  • build tolerance with morning and evening light
  • prioritize shade breaks in midday sun

Great Everyday Shoes—More Casual Than Expected
Size: 12, Color: Black/Optic White
Very comfortable and lightweight—great for everyday wear. Build quality feels solid, especially for the price. They lean a bit more casual than the photos suggest, but not in a bad way—still versatile enough to dress up or down.

Stylish, Comfortable, and GQ-Approved
Size: 9, Color: Navy Ink/Woodbury, Size: 9, Color: Navy Ink/Woodbury
I bought these Cole Haan Grandsport Journey Knit shoes for my husband, and he absolutely loves them. They’re stylish and really complete his outfits — very GQ vibes. He says they’re extremely comfortable on his feet and easy to wear all day. Great look, great fit, and definitely worth it. Highly recommend!

Extremely comfortable
Size: 10.5, Color: Navy Ink/Woodbury
As a manager for a very large corporate office campus, I do a LOT of walking. These shoes are a life saver. They look good, are comfortable, and so far, very durable. There are a lot of tile floors on this campus and when the shoes were new, they were a bit squeaky due to the soles adhering to the floors. Now they are as quiet as can be. I like them so much I asked for a pair in brown for Christmas - also awesome!
