Squalane enhances the delivery of ceramides into the stratum corneum and provides additional emollient benefit for barrier repair.
HA provides hydration while squalane forms an occlusive layer to prevent transepidermal water loss. The humectant-emollient combination.
Both mimic natural skin lipids. Jojoba closely resembles sebum composition while squalane mirrors skin surface lipids.
Squalane enhances delivery and skin tolerance of retinol by providing a lipophilic vehicle that reduces irritation.
Classic humectant + emollient combination. Glycerin attracts water, squalane locks it in. Simple but highly effective.
