Potassium hydroxide and collagen peptide: keep them apart

Keep them apart

Use them at different times of day, applying the peptide first and the potassium hydroxide later, because they clash in chemical balance. High alkalinity makes the collagen peptide lose its firmness and anti-aging benefits. You can space them out into separate morning and evening routines.
