the formulations containing polysaccharides lead to a higher degree of acceptance
by the volunteers and, consequently, better sensorial attributes (Fig. 4)
Skin application of hyaluronic acid-containing cosmetics has been reported to
achieve antiwrinkle effects via its ability to effectively moisturize and enhance the
elasticity of the skin (Basavaraj et al. 2010; Pavicic et al. 2011). Hyaluronic acid is a
very effective topical humectant, attracting water from the air to plump the skin. It
is also commonly used as an injectable dermal filler.
In addition to its moisturizing properties, the biodegradability of hyaluronic acid
also makes it very attractive for wound healing applications (Price et al. 2007; Teh
et al. 2012; Abbruzzese et al. 2009). It is used as a delivery system to transfer
keratinocyte cells from tissue culture to skin wounds, in particular burns, with high
rates of healing (Price et al. 2007).
