Skin Notes

Skin is complicated. Skincare doesn’t have to be.

A growing library of skin education, ingredient deep dives + the science behind the formulas I make.

After nearly a decade working with skin, I’ve learned that understanding how skin actually works makes it much easier to understand what it needs — and what it doesn’t.

Here we’ll talk about the skin barrier, tallow, fatty acids, TEWL, collagen + elastin, the epidermis + dermis, scalp health, ingredients, and the research behind it all.

No ingredient fear mongering. No miracle claims. Just skin science explained simply.
