Lactic acid and peptide-rich plasma: keep them apart

Keep them apart

Use lactic acid in the morning and peptide-rich plasma at night, because acid ruins the peptides. Acid breaks down the peptides so your skin misses out on their firming benefits. You can safely use both by applying them at different times of the day.

Questions and answers

Can you use lactic acid and peptide-rich plasma together?

Keep lactic acid and peptide-rich plasma apart because the low pH of the acid destabilizes the peptide bonds and reduces their bioactivity. Use them in separate steps or routines, such as AM and PM separation.

Which goes first, lactic acid or peptide-rich plasma?

Keep lactic acid and peptide-rich plasma apart by using them in separate steps or routines, such as AM and PM, because the low pH of lactic acid can break down and weaken peptides. Lovi fit ratings for combining them are not available.

Are lactic acid and peptide-rich plasma good for sensitive skin?

No, lactic acid and peptide-rich plasma should be kept apart in your routine because the low pH of the acid can break down the peptides and reduce their effectiveness. Sensitive skin should especially avoid combining them directly.
