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

Work well together

Use them together in the same routine, applying the [silk amino acids](https://lovi.care/skincare/sa/ingredients/silk-amino-acids) first and the [bio-placenta peptides](https://lovi.care/skincare/sa/ingredients/bio-placenta-peptides) right after for maximum hydration. Silk amino acids act as building blocks that help the bio-placenta peptides absorb better and work more effectively on your skin. You can use your usual strength of both products together, but if your skin feels sensitive, just apply them on alternate nights.
