Acetyl hexapeptide-3 and protease
Keep them apart
Use them at different times of day, applying acetyl hexapeptide-3 in the morning and protease at night, because they clash when mixed. Protease breaks down the firming bonds of acetyl hexapeptide-3, ruining the anti-aging benefits you want to see. You can easily fix this by applying them hours apart or on alternate days.
