Lactic acid and palmitoyl tripeptide-1
Keep them apart
Use lactic acid in the morning and palmitoyl tripeptide-1 at night, because the acid breaks down the peptide and stops it from working. Mixing them makes the peptide useless, so you miss out on smooth skin and firming results. Apply them at different times of day to let each ingredient work properly.

Questions and answers
Can you use lactic acid and palmitoyl tripeptide-1 together?
You should keep lactic acid and palmitoyl tripeptide-1 apart because the low pH of the acid destabilizes the peptide bonds and reduces its bioactivity.
Which goes first, lactic acid or palmitoyl tripeptide-1?
Keep lactic acid and palmitoyl tripeptide-1 apart by using them in separate steps or routines, such as AM and PM, because the low pH of lactic acid destabilizes the peptide.
Are lactic acid and palmitoyl tripeptide-1 good for sensitive skin?
Keep lactic acid and palmitoyl tripeptide-1 apart in your routine because the low pH of lactic acid may destabilize the peptide bonds. Mature and sensitive skin types should avoid combining them together.
