The humectant that does not leave skin tacky
Betaine — sometimes labelled trimethylglycine — is drawn from sugar beets and belongs to a family of compounds called osmolytes, which cells use to manage their own water balance. In a cosmetic formula it helps skin hold moisture and takes some of the sting out of surfactants. Its texture is a large part of the appeal: hydration without the tackiness glycerin can leave at higher concentrations.
Alastin is where you will meet it most in this store, running through Restorative Skin Complex, Ultra Nourishing Moisturizer, Ultra Light Moisturizer and Renewal Retinol 0.5. Outside that line it turns up in SkinCeuticals Daily Moisture and Obagi Daily Hydro-Drops Facial Serum.
Is betaine the same as betaine salicylate?
No, and the difference matters. Plain betaine is a humectant with no exfoliating action; betaine salicylate is a salicylic acid derivative. Nothing on this page exfoliates by virtue of containing betaine.
How to shop at ELLEMES
Because betaine sits in the base rather than the active slot, choose by what the product is for — a moisturizer, a retinol, a serum — and treat the humectant as a bonus.
