Acetyl hexapeptide-3 and citric acid: keep them apart

Keep them apart

Use them at different times of day, applying the acid first and the peptide second, because acid breaks down the peptide. Citric acid makes the skin too acidic, which ruins acetyl hexapeptide-3 and stops it from smoothing fine lines. You can use them in separate routines, like one in the morning and one at night.

Questions and answers

Can you use acetyl hexapeptide-3 and citric acid together?

Keep acetyl hexapeptide-3 and citric acid apart and use them in separate steps or routines, such as alternating between morning and evening, because the acidic environment of citric acid can destabilize peptide bonds and reduce their effectiveness.

Which goes first, acetyl hexapeptide-3 or citric acid?

Keep acetyl hexapeptide-3 and citric acid apart by using them in separate steps or routines, such as morning and evening separation. The acidic environment of citric acid destabilizes peptide bonds and may reduce the bioactivity of acetyl hexapeptide-3 if they are combined.

Are acetyl hexapeptide-3 and citric acid good for sensitive skin?

Keep acetyl hexapeptide-3 and citric acid apart because the low-pH environment of citric acid may destabilize the peptide and reduce its activity. Sensitive skin should especially avoid combining them in the same routine.
