Salicylic acid and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Use them at different times of day by applying salicylic acid in the morning and peptides at night because the acid ruins the peptide results. Salicylic acid is too acidic and breaks down the firming power of peptides, making them useless on your skin. You can easily fix this by using your acid in the morning and your peptides at night, or by waiting longer between applications.
