Figure 5: Transdermal permeation abilities of given FSCPs fractions. The permeation abilities of various molecular sizes of FSCPs were determined by the Franz-type diffusion cell model, performing at 1, 2, 3, 4, 6, and 24 hours. The amounts of total collagen peptides from the receptor solutions were determined by the BCA protein assay. “Mixture” indicates the FSCP hydrolates without ultracentrifugation membrane treatment. The results shown are a representative in 3 experiments.
