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

Work well together

Use [acetyl hexapeptide-3](https://lovi.care/skincare/ie/ingredients/acetyl-hexapeptide-3) and [theanine](https://lovi.care/skincare/ie/ingredients/theanine) together in the same routine, applying them at the same time to help your skin stay hydrated and firm. Theanine helps your skin stay balanced and hydrated so acetyl hexapeptide-3 can work better to smooth and firm your skin. You can continue using both together, but if your skin feels sensitive, you can apply them on alternate days.
