# Potassium hydroxide and peptide-rich plasma Page: https://lovi.care/skincare/ie/ingredients/potassium-hydroxide-and-peptide-rich-plasma The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Ireland. Keep them apart Use them at different times of day, applying the peptide product first and the [potassium hydroxide](https://lovi.care/skincare/ie/ingredients/potassium-hydroxide) later, because they clash and ruin results. High alkalinity makes peptides lose their stability and stop working well on the skin. The shopper can separate them by using one in the morning and the other at night. - [All about potassium hydroxide](https://lovi.care/skincare/ie/ingredients/potassium-hydroxide) - [All about peptide-rich plasma](https://lovi.care/skincare/ie/ingredients/peptide-rich-plasma) ### [Potassium hydroxide](https://lovi.care/skincare/ie/ingredients/potassium-hydroxide) products - [Glytone Mild Gel Cleanser](https://lovi.care/skincare/ie/p/glytone/mild-gel-cleanser/for/dark-spots) — High fit ### [Peptide-rich plasma](https://lovi.care/skincare/ie/ingredients/peptide-rich-plasma) products - [Eighth Day Regenerative Serum](https://lovi.care/skincare/ie/p/eighth-day/regenerative-serum/for/dry-sensitive-skin) — High fit ## Questions and answers ### Can you use potassium hydroxide and peptide-rich plasma together? No, you should keep [potassium hydroxide](https://lovi.care/skincare/ie/ingredients/potassium-hydroxide) and [peptide-rich plasma](https://lovi.care/skincare/ie/ingredients/peptide-rich-plasma) apart because highly alkaline environments cause peptides to lose their stability and activity. ### Which goes first, potassium hydroxide or peptide-rich plasma? Keep potassium hydroxide and peptide-rich plasma apart. Potassium hydroxide creates a highly alkaline environment that may cause peptides to lose their stability and activity. ### Are potassium hydroxide and peptide-rich plasma good for sensitive skin? Potassium hydroxide and peptide-rich plasma should be kept apart in your skincare routine. Potassium hydroxide creates a highly alkaline environment that causes peptides to lose stability and activity. ## Other combinations - Keep them apart: [Adapalene and peptide-rich plasma](https://lovi.care/skincare/ie/ingredients/adapalene-and-peptide-rich-plasma) -
