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

Pair and Principia are two distinct skincare lines known for their thoughtful cleansers, targeted [serums](https://lovi.care/skincare/sg/ingredients/serum), and meticulously crafted formulas. Pair suits acne-prone skin best with gentle preparations like the Acne Cream W, while the brand helps address stubborn blemishes and restore balance. Meanwhile, Principia suits balanced to oily skin best, offering precise offerings such as the Gel de Limpeza GL-01 to maintain a healthy complexion. Ultimately, both brands differ through their specific product types and targeted concerns, despite their shared dedication to clarity.

Pair is a Japanese skincare brand founded in 2000 and owned by Lion Corporation since 2004.
