Effect of Oil Type on Stability of W/O/W Emulsions

The behavior of the w/o/w emulsion system and the stability of the oil membrane depend on the type of oil used to make the emulsion. Conductimetric analysis of the release of entrapped marker magnesium sulfate showed that the highest release of the marker occurred in emulsions based on oils from the triglyceride group. Emulsions based on hydrocarbon oils showed the best stability.

Properties of a Pseudoceramide Multi-Lamellar Emulsion In Vitro and In Vivo

Tests of a pseudoceramide multi-lamellar emulsion formulation for its stability and its assistance to barrier recovery in vivo on damaged skin suggest dermatologic and cosmetic possibilities.

Types of Skin Aging

The process of skin aging is complex and multifactorial, as structural, functional and aesthetic changes happen at a variable rate. It is misleading to consider skin aging as a uniform biological event; several distinct biological processes may occur concurrently. There are five types of skin aging, including: intrinsic, extrinsic, lifestyle, hormonal or catabolic.
