Rosette's proprietary micronization technique

Natural ceramide has outstanding benefits for the skin, but it is also a difficult ingredient to formulate due to poor solubility. At Rosette, we apply a proprietary micronization technique to boost the solubility of natural ceramide so that it penetrates uniformly throughout the stratum corneum. The fine particles are micronized using an ultra-high-pressure processing device. The uniform size also helps the ceramide absorb more readily into the skin.

Micronized natural ceramide

The micronization process has been shown to reduce the natural ceramide particles to an average diameter of just 1/760th of their original size while also making them more uniform.
