Beauty, in a shifting state.

Serotonin is a beauty brand designed around expression, not correction.

We believe expression isn’t fixed. It shifts with mood, light, context, and time. So we created products that adapt. Designed to be layered, worn differently, and lived in.

A Note from Our Founder

Makeup has always inspired me, sparked my confidence, and lifted my mood. I wanted to share that joy with the world by creating beauty products so flexible, they feel personal. That's why we created makeup that's clean, vegan and cruelty-free. Beauty that respects the skin and feels as good as it looks. Every product is thoughtfully made, intuitive, and designed for self-expression. Beauty is not about rules. It is about how you feel. Every version of you. Iulia xx

Umber Equinox

Built for individuality, not ideals.

We design products that adapt to real faces, real moods, and real life. Without asking you to conform.

Expression over correction.

Nothing here is meant to fix you. Our formulas are made to layer, shift, and be worn your way.

Intentional colors.

Every shade is created in conversation with the rest, so colors layer naturally, across products and across looks.
