From: Stabilization of ferulic acid in topical gel formulation via nanoencapsulation and pH optimization

Cumulative active release (%) from the gel formulations containing nanoencapsulated ferulic acid: (a) Gel A versus Gel B and (b) 0.5% (Gel B) versus 0.25% (Gel C) nanoencapsulated ferulic acid gel. Data represent mean ± SD (n = 3). *Significant difference: Gel A versus Gel B (p < 0.05).
