COSRX vs Principia

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

COSRX and Principia are two thoughtful skincare lines offering reliable cleansers, targeted serums, and daily moisturizers for diverse complexions. COSRX suits oily and oily acne-prone skin best with formulas incorporating hyaluronic acid, glycerin, and niacinamide to balance moisture, reduce cell damage, and decrease hyperpigmentation. Principia suits balanced to oily skin best, delivering precise cleansers like the Gel de Limpeza GL-01 to help maintain a healthy, balanced complexion. While both brands feature targeted solutions for specific concerns, the former is a Korean brand known for its iconic snail mucin and propolis products, whereas the latter is widely celebrated for its minimalist, science-driven approach.

COSRX is a Korean skincare brand founded in 2013 and owned by Amorepacific Group since 2024.
