Is Betaine a Good Ingredient?
This is a well-studied osmolyte and humectant that reliably boosts moisture balance, with good formula stability and a very low likelihood of irritation across skin types, which is what earns it a Great rating.

Helps keep skin cushioned and bouncy by attracting water and maintaining a comfortable feel, and it's gentle enough for reactive complexions to offset dryness from cleansing or environmental stress.

Common in hydrating serums, daily moisturizers, and eye creams, and also added to gentle cleansers and conditioners for a softer finish.
Before you use it
