The increase in skin hydration after application of emollients with different amounts of lipids.
Emollients can increase the water content in the stratum corneum by delivery of their water to the skin, and by occlusion. These two mechanisms were studied using three preparations with different concentrations of lipids. The products were applied to the skin and then removed by cleaning the surface after 5 and 40 min. ⋯ The occlusion caused an increase of water in the skin, which resulted in a release of water following removal of the products. The release was related to the reduction of water loss. Thus petrolatum gave a higher release of water than the other emollients.
