Delivery Systems
Whether we’re talking skin care, anti-aging, makeup or hair care, without an effective delivery system the product will never achieve the end result. There are many delivery systems available—emulsions, microemulsions, polymeric emulsifiers and liposomes—just to name a few, but a new system being touted for its superiority is liquid crystals. According to Steve Herman’s article on GCIMagazine.com, liquid crystals are “an organized state of matter (thus crystal), but they can still flow (thus liquid), so they form a unique family of materials.”
The question is, are these liquid crystals as great as they say they are? Can they deliver on their promises? Problem is, liquid crystals are sensitive to temperature, and in order for them to effectively “impact the intercellular matrix, the lipids must penetrate the mighty barrier of the stratum corneum.” But studies may support these structures in moisturization and other beneficial effects.
