Shake-Induced Temporary Ion-Pairing Between Lecithin and Glycolic Acid for Enhanced Exfoliation in a Novel Biphasic Serum: Comparative Ex Vivo and in Vivo Randomised Studies
{{output}}
Background: Chemical exfoliation efficacy is significantly limited by pH-dependent permeability reduction above the pKa of glycolic acid (3.83), constraining consumer product development. ... ...
