Some By Mi vs ISDIN

Rated by Lovi · Unbiased, science-based skincare AI trained on real user outcomes · How the Fit score works

Some By Mi and ISDIN are distinct skincare brands, with the Korean line founded in 2016 and the Spanish house established in 1975, offering diverse products ranging from serums and cleansers to sunscreens and moisturizers. While both accommodate sensitive skin, the former relies on niacinamide, centella asiatica, and salicylic acid to best suit dry sensitive skin, dry skin, acne-prone skin, skin with dark spots, and mature skin. Conversely, the latter applies thoughtful daily care formulas to best support sensitive skin and acne-prone skin through gentle creations that respect delicate moisture barriers. Ultimately, they differ in their heritage and specific ingredient approaches, providing tailored solutions for maintaining a balanced complexion.

Some By Mi is a Korean skincare brand founded in 2016 and owned by JKL Partners since 2021.
