Betaine
A naturally occurring osmolyte that helps cells manage their water balance.
On the label: Betaine. Also known as Trimethylglycine, Glycine betaine.
What it does for you
Takes the edge off. It helps a high-active formula feel comfortable rather than tight.
Why we use it
Tolerance is a feature, not an afterthought.
Mechanism
Betaine helps skin cells hold water without disrupting their internal chemistry, which supports hydration and reduces the sting some actives can cause.
