GCL/GCP GELS ENHANCE SKIN DELIVERY OF MAP 283 Figure 5. MAP fl ux through skin from various polymer gels. (*p 0.05, **p 0.01, ***p 0.005)

JOURNAL OF COSMETIC SCIENCE 284 amounts of MAP were deposited in both epidermis and dermis strata, presumably due to the higher viscosity of both gels. CONCLUSIONS GCP hydrogel has been reported as erodible controlled-release systems for the delivery of both hydrophilic and hydrophobic molecules (13,14). In this study, we showed that Figure 6.
