# Principia vs Azclear Page: https://lovi.care/skincare/uk/compare/principia-vs-azclear The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for the United Kingdom. Principia and Azclear are popular skincare lines recognized for their gentle, targeted approach to maintaining a healthy complexion. Principia is widely loved for its thoughtful cleansers and precise formulas that suit balanced to oily skin best, featuring standout products like the Gel de Limpeza GL-01 for acne-prone skin. Conversely, the brand is deeply appreciated for its soothing [serums](https://lovi.care/skincare/uk/ingredients/serum) and carefully balanced formulas that suit sensitive, acne-prone, and reactive skin types best because of their gentle nature, highlighted by the Medicated Lotion for acne-prone skin. While both offerings help maintain and nurture a balanced complexion, they differ primarily in their product types and the specific skin types they suit best.
