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 [benzoyl peroxide](https://lovi.care/skincare/ie/ingredients/benzoyl-peroxide) in the morning and peptides at night, because benzoyl peroxide ruins peptide effectiveness. Benzoyl peroxide breaks down the helpful parts of peptides, making the peptide treatment useless on your skin. You can easily fix this by applying benzoyl peroxide and peptides during separate parts of your daily routine.
