Encapsulation, explained.
Wrapping an active in a lipid shell delays release, cuts sting, and lets the skin see the molecule at a lower peak concentration for longer.

Retinol delivered raw is essentially a shock. The active hits the surface at peak concentration and the skin protests, often visibly, for two to three weeks. Encapsulation wraps the molecule in a lipid or polymer shell that dissolves slowly across four to eight hours.
The peak concentration the skin ever sees is lower. The area under the curve, over the course of one night, is roughly the same. In practice, tolerance rises, retinisation symptoms fall, and adherence increases because nothing is stinging.
Forté is engineered around that principle. So is the Retinol Night cream at a higher percentage. Same rules, different application.

Nine indoor hours a day at 22°C and 30% relative humidity is a small desert. The routine should acknowledge it.
