Potassium hydroxide and palmitoyl tripeptide-1: keep them apart

Keep them apart

Apply the peptide product first and the potassium hydroxide product later, because high alkalinity destroys peptide stability. Potassium hydroxide makes the skin environment too basic, which ruins the firming benefits of palmitoyl tripeptide-1. The shopper can use them on alternate nights or switch to a balanced cleanser to protect the results.
