Our take
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.
What it does
Skin Benefits
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.
Where you'll find it
Uses in Skincare & Cosmetics
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
Safety
Generally well tolerated with a low irritation profile at typical cosmetic levels; sensitization is uncommon. Suitable for daily use unless an individual sensitivity is known.
