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 known for thoughtful selections of serums, cleansers, toners, moisturizers, and eye products. The Korean brand founded in 2016 features niacinamide, centella asiatica, and salicylic acid to fit dry sensitive skin and dry skin best, whereas the other brand relies on niacinamide and glycerin to suit mature skin and acne-prone skin best. Both incorporate niacinamide to address hyperpigmentation, wrinkles, and aging signs, though the former utilizes salicylic acid for acne and the latter employs glycerin for hydration and barrier function.

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