Some By Mi vs Olay

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

Some By Mi and Olay are two distinct skincare lines offering serums, cleansers, toners, moisturizers, and more. The Korean brand founded in 2016 relies on niacinamide, centella asiatica, and salicylic acid to suit dry sensitive skin and skin with dark spots best, whereas the second option utilizes niacinamide and glycerin to care for dry skin and acne-prone skin. While both companies address hyperpigmentation and aging through niacinamide, they differ as the former uses salicylic acid to reduce acne lesions and maintain skin clarity, while the latter employs glycerin to improve hydration and barrier function.

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