Soy Protein & Rabdosia: The Complete Guide

These botanical actives support the look of firmer, smoother skin — the supporting cast in our neck-and-chest treatment. This guide explains what they are.

Soy protein

Soy is rich in proteins and isoflavones. In skincare, soy protein helps condition and support the look of firmer, more elastic skin, and is a long-standing botanical for mature and thinning skin.

Rabdosia (with Siegesbeckia)

Rabdosia rubescens and Siegesbeckia orientalis are botanical extracts used to support the skin’s smoothness and comfort, complementing the firming actives in a formula.

Where we use them
