# Citric acid and theanine

Page: https://lovi.care/skincare/ae/ingredients/citric-acid-and-theanine

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

Work well together

Use them together in the same routine, applying the [citric acid](https://lovi.care/skincare/ae/ingredients/citric-acid) first and the [theanine](https://lovi.care/skincare/ae/ingredients/theanine) after, for a gentle and balanced glow. The citric acid mildly adjusts your skin while the theanine keeps it feeling calm and hydrated. You can easily adjust by using a gentler strength if your skin feels sensitive.
