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

Dr. Barbara Sturm and DOT & KEY are distinct skincare brands designed to address different needs through specialized formulations. The German line, founded in 2014, is known for gentle moisturizers, clarifying exfoliants, and nourishing [serums](https://lovi.care/skincare/ie/ingredients/serum) that suit sensitive, dry, and balanced skin best. Conversely, the Indian collection, founded in 2018, is celebrated for sensorially pleasing sunscreens with lightweight textures that favor balanced, combination, and normal skin. While both offer thoughtfully crafted daily essentials, they differ significantly in their ingredient focus, geographic origins, and ideal skin profiles.

Dr. Barbara Sturm is a German skincare brand founded in 2014 and owned by Puig since 2024.
