Hexapeptide-9 and squalene: work well together

Work well together

Use them together in the same routine, applying the squalene after the hexapeptide-9, because the oil helps the peptide sink in better. The squalene helps the hexapeptide-9 absorb more easily so your skin feels stronger and smoother. You do not need to change anything since this combination is very gentle.
