Retinol is the benchmark anti-aging active and one of the hardest to formulate. Exposed to oxygen, light and other ingredients it oxidizes: formulas turn yellow, lose potency on the shelf and can irritate skin. CelluCaps™ RL encapsulates pure retinol in cellulose-based microcapsules using Tagra’s Release on Demand™ technology. The capsules keep retinol isolated through scale-up and storage, then break on gentle rubbing so it reaches the skin fresh. The oil-soluble active becomes a powder that disperses across all phases of a formulation.
