Betaine Application Order: Where Should It Go?
Betaine is a moisturizing ingredient that holds onto moisture, so it isn't fixed to one particular step in a skincare routine. It can be included in light formulas like toners and essences, as well as heavier formulas like creams. Rather than focusing on 'which step to apply it,' it's more important to look at what role it's designed to play within the entire ingredient list. When used in a final step alongside oil-based ingredients, it can help seal in moisture so it doesn't evaporate.
