Collagen peptide and isopropyl alcohol: keep them apart

Keep them apart

Use them at different times of day, applying the peptide first and alcohol later, because mixing them cancels out the benefits. Alcohol breaks down the peptide structure so your skin misses out on the firming benefits. You can safely use them by putting at least a few hours between applications or switching to a milder product.

Questions and answers

Can you use collagen peptide and isopropyl alcohol together?

No, you should keep collagen peptide and isopropyl alcohol apart because alcohol can denature the peptide structure and reduce its effectiveness. It is best to avoid combining them in the same routine to protect your skin barrier.

Which goes first, collagen peptide or isopropyl alcohol?

Keep collagen peptide and isopropyl alcohol apart in your routine because the alcohol can break down the peptide structure and reduce how well it works. Apply your collagen peptide product first and save alcohol-based products for a completely separate routine.

Are collagen peptide and isopropyl alcohol good for sensitive skin?

No, collagen peptide and isopropyl alcohol should be kept apart in your routine because isopropyl alcohol may denature peptide structure and reduce bioavailability. This combination is especially unsuitable for dry and sensitive skin types.
