The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for the United Kingdom.

Keep them apart

Use them at different times of day, applying the peptide first and the [potassium hydroxide](https://lovi.care/skincare/uk/ingredients/potassium-hydroxide) later, because they clash and cancel each other out. The strong alkaline ingredient breaks down the delicate peptide, meaning the peptide loses its ability to smooth fine lines and firm the skin. The shopper can switch to a gentler product or wait longer between applying them to see better results.

## Questions and answers

### Can you use potassium hydroxide and palmitoyl pentapeptide-4 together?

You should keep [potassium hydroxide](https://lovi.care/skincare/uk/ingredients/potassium-hydroxide) and [palmitoyl pentapeptide-4](https://lovi.care/skincare/uk/ingredients/palmitoyl-pentapeptide-4) apart in your routine because highly alkaline environments cause peptides to lose their stability and activity.

### Which goes first, potassium hydroxide or palmitoyl pentapeptide-4?

Keep potassium hydroxide and palmitoyl pentapeptide-4 apart because peptides lose stability in alkaline environments. Use them in separate routines to protect the peptide activity.

### Are potassium hydroxide and palmitoyl pentapeptide-4 good for sensitive skin?

Potassium hydroxide and palmitoyl pentapeptide-4 should be kept apart in your routine because highly alkaline environments cause peptides to lose their stability and activity. Palmitoyl pentapeptide-4 may help improve the appearance of wrinkles and fine lines.
