# Bio-placenta peptides and polyvinyl alcohol Page: https://lovi.care/skincare/it/ingredients/bio-placenta-peptides-and-polyvinyl-alcohol The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Italy. Keep them apart Apply [bio-placenta peptides](https://lovi.care/skincare/it/ingredients/bio-placenta-peptides) in the morning and [polyvinyl alcohol](https://lovi.care/skincare/it/ingredients/polyvinyl-alcohol) at night because strong alcohols can ruin the peptides. Polyvinyl alcohol can break down the delicate structure of the peptides, making them much less effective on your skin. To get the best results, use a gentler product or wait longer between applying them. - [All about bio-placenta peptides](https://lovi.care/skincare/it/ingredients/bio-placenta-peptides) - [All about polyvinyl alcohol](https://lovi.care/skincare/it/ingredients/polyvinyl-alcohol) ### [Bio-placenta peptides](https://lovi.care/skincare/it/ingredients/bio-placenta-peptides) products - [LION POSE PEP TALK](https://lovi.care/skincare/it/p/lion-pose/pep-talk/for/dry-skin) — Average fit ### [Polyvinyl alcohol](https://lovi.care/skincare/it/ingredients/polyvinyl-alcohol) products - [Olay Cleansing Melts](https://lovi.care/skincare/it/p/olay/cleansing-melts/for/dark-spots) — Average fit ## Questions and answers ### Can you use bio-placenta peptides and polyvinyl alcohol together? No, you should keep [bio-placenta peptides](https://lovi.care/skincare/it/ingredients/bio-placenta-peptides) and [polyvinyl alcohol](https://lovi.care/skincare/it/ingredients/polyvinyl-alcohol) apart because strong surfactants and alcohols may denature the peptide structure and reduce bioavailability. Lovi rates this combination as having average compatibility. ### Which goes first, bio-placenta peptides or polyvinyl alcohol? Keep bio-placenta peptides and polyvinyl alcohol apart in your routine because mixing them may break down the peptide structure and reduce how well it works. Use them in separate routines instead. ### Are bio-placenta peptides and polyvinyl alcohol good for sensitive skin? No, you should keep bio-placenta peptides and polyvinyl alcohol apart in your routine because strong alcohols can denature the peptide structure and reduce bioavailability. This combination may irritate dry and sensitive skin types. ## Other combinations - Keep them apart: [Adapalene and bio-placenta peptides](https://lovi.care/skincare/it/ingredients/adapalene-and-bio-placenta-peptides) -
