Page: https://lovi.care/skincare/compare/allies-of-skin-vs-ren-clean-skincare

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

Allies of Skin and REN Clean Skincare are distinct skincare lines created to nurture the complexion. Allies of Skin is loved for its luxurious moisturizers, potent [serums](https://lovi.care/skincare/ingredients/serum), and targeted eye products formulated with powerhouse ingredients like [niacinamide](https://lovi.care/skincare/ingredients/niacinamide), which suit dry skin and acne-prone skin best. REN Clean Skincare is a British skincare brand founded in 2000 and owned by Unilever since 2015 that is universally loved for its gentle toners and thoughtfully crafted formulas, suiting sensitive, reactive, and dull skin types best. While both balance the complexion, they differ as the brand from Britain uses clean, non-irritating, botanical precision, whereas the other relies on deeply nourishing and clarifying formulations.

REN Clean Skincare is a British skincare brand founded in 2000 and owned by Unilever since 2015.
