How We Calculate Cosmetic Biodegradability at The Today Project
What does biodegradable really mean in cosmetics? At The Today Project, we evaluate biodegradability ingredient by ingredient, using quantitative formulation data and recognised biodegradation criteria rather than assumptions based on natural origin.


Vitamin C, Niacinamide, Hyaluronic Acid, Peptides, antioxidants and barrier-supporting ingredients — do you really need a separate serum for each? Discover the Skincoach approach to a smarter, simpler skincare routine.
