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 established skincare names offering diverse portfolios of serums, cleansers, toners, and moisturizers. The Korean brand, founded in 2016, features niacinamide, centella asiatica, and salicylic acid to best suit dark spots and dry sensitive skin, whereas the universally loved American brand relies on nourishing niacinamide and glycerin to support mature and dry skin. While both utilize niacinamide to improve aging signs and pigmentation, the former uniquely leverages salicylic acid for acne and centella asiatica for soothing care, while the latter centers its deep replenishment on glycerin and targeted barrier support.

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