# Vitamin C and copper peptide Page: https://lovi.care/skincare/nl/ingredients/vitamin-c-and-copper-peptide The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for the Netherlands. Keep them apart Apply [vitamin C](https://lovi.care/skincare/nl/ingredients/vitamin-c) in the morning and [copper peptides](https://lovi.care/skincare/nl/ingredients/copper-peptide) at night, because combining them makes both ingredients less effective. [Copper](https://lovi.care/skincare/nl/ingredients/copper) reacts with vitamin C and neutralizes their anti-aging benefits. You can use both by separating them into different times of day.

No, you should keep [vitamin C](https://lovi.care/skincare/nl/ingredients/vitamin-c) and [copper peptide](https://lovi.care/skincare/nl/ingredients/copper-peptide) apart in separate routines because [copper](https://lovi.care/skincare/nl/ingredients/copper) acts as an oxidation catalyst that reduces peptide efficacy. Perricone MD Cold Plasma Plus+ is a product on this page that contains both ingredients. ### Which goes first, vitamin C or copper peptide? Keep vitamin C and copper peptide apart by using them in separate routines because copper acts as an oxidation catalyst that reduces peptide efficacy. Perricone MD Cold Plasma Plus+ is an exception that combines both in one product. ### Are vitamin C and copper peptide good for sensitive skin? Vitamin C and copper peptide should be kept apart in separate routines because combining them may reduce their efficacy. Perricone MD Cold Plasma Plus+ is an example of a product containing both. ## Research on vitamin C and copper peptide - [Topical ascorbic acid on photoaged skin.
