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
Soy protein and Rabdosia support the firming actives in Nécolleté Age Reversal for Neck and Chest. See the Ingredient Glossary.
