A story worth sharing

Skincare is chemistry. In your hands, it's Alchemy. You've been through some sh*t. Look how you shine now.

Meet the Alchemy Brush

Made for pros who demand better.

Dense, silky, synthetic mink bristles that feel like a whisper on the skin. Your clients will feel the difference from the very first stroke.

One brush. Three ways to alchemize: cleanse, serum, and mask.

Glossy white handle, a flash of chrome, white bristles. Clean enough for the most clinical treatment room, and pretty enough to leave out on the counter.

3 Ways to Alchemize

Cleanse

Work cleanser in with soft, even strokes, every inch covered.

Serum

Layer serums evenly, one silky pass at a time.

Mask

Paint masks on in smooth, even coats. Clean edges, every time.

Treatment Bundles · Only at Agent Rx

The full treatment, in one box.

Pair Alchemy with the Cloud Brush, our luxury cleansing brush with natural bristles. Six of each, with The Glossary Guide included.

Free with 6 brushes or more

The Glossary Guide

Ten of our favorite treatment room cocktails for cleansing, serum, and mask, five from me and five from Rosanna. And it keeps growing, with new cocktails added over time.

Included with any 6-pack or 12-pack (Alchemy or Cloud) and both Treatment Bundles. Not included with a 2-pack.

A note from Cosi

Why We Made Alchemy

I've spent years watching pros make do with tools that were never designed for them. Brushes that scratch, shed, and give out after a month of real treatment days. Our industry deserves better, so Rosanna and I built it.

Alchemy takes you from cleanse to serum to mask with one brush. Chrome is for every esthetician who has been through it and came out shining. That's you. Now go make something.
