Polysaccharide Extracted from Laminaria japonica Delays Intrinsic Skin Aging in Mice

Figure 5

Antioxidant enzyme expression is upregulated by LP treatment in aging skin. Expression levels of (a) MDA, (b) SOD, (c) GSH-Px, and (d) CAT in the skin tissue of young control mice and aging mice without or with LP-L, LP-M, LP-H, or Vit. E treatment, as determined by western blotting. Values represent mean ± SD (). and versus aging group.
