# Clarins vs Principia

Page: https://lovi.care/skincare/ca/compare/clarins-vs-principia

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

Clarins and Principia are two distinct skincare lines known for differing approaches to daily routines. The former offers luxurious moisturizers, potent [serums](https://lovi.care/skincare/ca/ingredients/serum), soothing eye products, and gentle toners enriched with shea and squalane, which suit sensitive and dry sensitive skin best by reducing redness, protecting the skin, increasing [collagen](https://lovi.care/skincare/ca/ingredients/collagen), and fighting damage. Meanwhile, the latter is widely loved for thoughtful cleansers and precise formulas that suit balanced to oily skin best to help maintain a healthy, balanced complexion. Ultimately, both brands differ through their signature ingredients, target skin types, and specialized treatments designed for specific concerns.

Clarins is a French skincare brand founded in 1954 and owned by Famille C (Groupe Clarins).
