# Glycerin and bio-placenta peptides Page: https://lovi.care/skincare/ca/ingredients/glycerin-and-bio-placenta-peptides The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Canada. Work well together Use them together by applying the [glycerin](https://lovi.care/skincare/ca/ingredients/glycerin) [serum](https://lovi.care/skincare/ca/ingredients/serum) first, because extra moisture helps the peptides soak into the skin better. Glycerin quenches the skin with moisture while [bio-placenta peptides](https://lovi.care/skincare/ca/ingredients/bio-placenta-peptides) help firmness, and both work together to keep the skin barrier strong and healthy. You can easily use them in the same routine, but try applying a thinner layer if you want to test how your skin reacts.

Yes, you can use [glycerin](https://lovi.care/skincare/ca/ingredients/glycerin) and [bio-placenta peptides](https://lovi.care/skincare/ca/ingredients/bio-placenta-peptides) together because humectants help increase peptide diffusion and support skin barrier integrity. You can combine them for enhanced hydration. ### Which goes first, glycerin or bio-placenta peptides? Glycerin goes first by layering a hydrating [serum](https://lovi.care/skincare/ca/ingredients/serum) beneath your peptide product. This combination helps increase hydration and supports barrier integrity for all skin types. ### Are glycerin and bio-placenta peptides good for sensitive skin? Glycerin and bio-placenta peptides work well together to enhance hydration and support skin barrier integrity for all skin types, including sensitive skin. Combining them helps increase peptide diffusion. ## Research on glycerin and bio-placenta peptides - [The 24-hour skin hydration and barrier function effects of a hyaluronic 1%, glycerin 5%, and Centella asiatica stem cells extract moisturizing fluid: an intra-subject, randomized, assessor-blinded study](https://pubmed.ncbi.nlm.nih.gov/28860834/) Glycerin · Clinical, Cosmetic and Investigational Dermatology, 2017 ## Other combinations -
