Betaine

Betaine skincare is a hydration-focused category for routines that need moisture balance, skin comfort, and a gentler feel across daily treatment steps.

As a humectant-led support ingredient, betaine is often paired with calming and moisture-binding formulas that help keep toner, ampoule, cream, mask, and cleanser routines feeling more balanced.

Shop betaine toners, ampoules, creams, masks, cleansers, and sunscreen selected for lightweight hydration, routine flexibility, and targeted care across different skin goals.

Protoclinical builds ingredient collections with a clinical, protocol-oriented approach so you can choose formulas that support barrier function, texture, and steady hydration without overcomplicating the routine.
