Your skin is losing water right now. That sounds alarming. It isn’t. Water naturally moves through the skin and evaporates into the environment. The interesting part is how well your outer skin barrier controls that loss. That’s where TEWL comes in. 💧 DERMAPROTOCOLS SCIENCE FILE #05 THE 20-SECOND EXPLANATION What Is TEWL? TEWL stands for…
Glycolic. Lactic. Salicylic. Gluconolactone. At some point, skincare stopped sounding like skincare and started sounding like a chemistry exam. The good news? You don’t need to memorize every acid on the shelf. You just need to know what problem you’re trying to solve. THE 20-SECOND ACID TEST What’s Bothering Your Skin? ✨ Dull, rough or…
The acne is finally calming down. Now you’re left with the souvenirs: brown marks, red marks and an increasingly crowded skincare shelf. One person tells you to buy vitamin C.

The surface of your skin is home to a complex and constantly changing community of microorganisms known collectively as…
Your forehead looks shiny by lunchtime, but your cheeks feel tight after cleansing. Your skin produces plenty of oil—yet somehow still feels dry. It sounds contradictory, but it isn’t. Oil and water are two different parts of the skin equation, which means skin can feel dehydrated while still producing noticeable sebum. Quick answer: Oily skin…
