RevivHair Max gets an upgrade:
RevivHair Max Hair Stimulating Serum now encapsulates its existing primary hair actives Redensyl, Capixyl, and Procapil, in a phospholipid microsphere, which "containerizes" it.
Such microsphere containers form a transfer system that enhances penetration, as they transfer the actives to the capillary bulbs.
With such a liposome we can enhance the delivery of actives to maximize their ability to effectively penetrate, boosting their efficacy, strength and bioavailability.
Since such a container also has a timed-release benefit, since it releases its actives over time compared to non-encapsulated actives.
How are our liposomes designed?
These microscopic vesicles consist of an aqueous center with a phospholipid membrane. Phospholipids contain a glycerol bonded to two fatty acids and a phosphate group with a polar head. The fatty acid portion of this biomolecule is hydrophobic and is located toward the outside of the lipid bilayer, and the phosphate group is hydrophilic and faces the aqueous interior.
These phospholipid walls are identical to those that comprise human cell membranes, and are readily compatible with epidermal surface lipids, the skin’s primary moisture barrier.
When a liposome fuses with epidermal lipids, the epidermal lipid structure becomes overloaded with water and out of equilibrium. To restore equilibrium, the water and phospholipid, as well as the loaded actives, are rapidly churned through the top cell layers of the stratum corneum. Enhanced delivery of the active occurs as it is rapidly carried down through the stratum corneum.
Liposomes’ proven delivery system yields a multitude of benefits; enhancing the penetration of actives yielding increased efficacy, offering time release mechanisms, and protecting and delivering otherwise unstable ingredients.
Liposomes are also known to improve the skin barrier function and decrease transepidermal water loss (TEWL) shortly after application. In addition, phospholipids contain a high content of phosphatidylcholine which has excellent moisturizing properties.
