Isopropyl alcohol and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Apply isopropyl alcohol and palmitoyl pentapeptide-4 at different times of day, using the alcohol in the morning and the peptide at night. Isopropyl alcohol can weaken and break down the anti-aging benefits of the peptide, making it much less effective on your skin. To fix this, you can switch to a gentler alcohol-free toner or space the two products further apart.

Questions and answers

Can you use isopropyl alcohol and palmitoyl pentapeptide-4 together?

Keep isopropyl alcohol and palmitoyl pentapeptide-4 apart because alcohol can denature the peptide structure and reduce its effectiveness. Instead, use them in separate routines to protect your skin.

Which goes first, isopropyl alcohol or palmitoyl pentapeptide-4?

Keep isopropyl alcohol and palmitoyl pentapeptide-4 apart in your routine because high solvent activity can break down the peptide structure. Apply them at different times of day to avoid reducing the effectiveness of the peptide.

Are isopropyl alcohol and palmitoyl pentapeptide-4 good for sensitive skin?

No, you should keep isopropyl alcohol and palmitoyl pentapeptide-4 apart because strong alcohols can denature the peptide structure and reduce its bioavailability, which is especially harsh for dry and sensitive skin. It is best to avoid combining them in the same routine.
