# Betaine and peptide-rich plasma Page: https://lovi.care/skincare/de/ingredients/betaine-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 Germany. Work well together Use [betaine](https://lovi.care/skincare/de/ingredients/betaine) first to hydrate the skin, followed by the peptide [serum](https://lovi.care/skincare/de/ingredients/serum) to boost absorption and firmness. Betaine draws in moisture to help the peptide serum sink in deeper and work more effectively. You can keep using both as normal, but just apply the hydrating betaine layer first.

Yes, you can use [betaine](https://lovi.care/skincare/de/ingredients/betaine) and [peptide-rich plasma](https://lovi.care/skincare/de/ingredients/peptide-rich-plasma) together because humectants like betaine pair well with peptides to enhance hydration and peptide delivery. You can combine them for all skin types, especially if your skin is dry or mature. ### Which goes first, betaine or peptide-rich plasma? Betaine goes first, as a hydrating [serum](https://lovi.care/skincare/de/ingredients/serum) with humectants like betaine should be layered beneath a peptide product to enhance peptide diffusion and support barrier integrity. Lovi rates this combination as Superior for all skin types, especially dry and mature. ### Are betaine and peptide-rich plasma good for sensitive skin? Yes, betaine and peptide-rich plasma work well together to enhance hydration and support skin barrier integrity, making them beneficial for all skin types including sensitive skin. ## Research on betaine and peptide-rich plasma -
