Hexapeptide and protease
Keep them apart
Use them at different times of day, applying the peptide product in the morning and the protease at night, because they cancel each other out. Protease breaks down the firming peptides so you miss out on anti-aging results. Separate your usage or use them on alternate nights to get the full benefit.
