COSRX is beloved for its thoughtful array of [serums](https://lovi.care/skincare/ie/ingredients/serum), moisturizers, cleansers, masks, and more, which harness key ingredients like [hyaluronic acid](https://lovi.care/skincare/ie/ingredients/hyaluronic-acid), [glycerin](https://lovi.care/skincare/ie/ingredients/glycerin), and [niacinamide](https://lovi.care/skincare/ie/ingredients/niacinamide). Its products suit oily skin and sensitive skin best, owing to formulations that balance moisture and soothe irritation. For particular concerns, the standout products include the Advanced [Snail Mucin](https://lovi.care/skincare/ie/ingredients/snail-mucin) Gel Cleanser for acne-prone skin, the Full Fit [Propolis](https://lovi.care/skincare/ie/ingredients/propolis) Synergy Toner for skin with dark spots, and the [Centella Water](https://lovi.care/skincare/ie/ingredients/centella-asiatica) Alcohol-Free Toner for mature skin. Together, the brand's key ingredients work to lengthen toxin duration and reduce cell damage, significantly increase skin hydration and barrier function, and significantly decrease hyperpigmentation and reduce skin aging.

## About the Lovi Fit

Lovi: Unbiased, science-based skincare AI trained on real user outcomes.

Lovi rates every product from its full ingredient list with brand-independent rules its dermatologists and cosmetic chemists build and review, and personalizes every pick with AI trained on the real results of millions of users. Lovi trains its fit score models on a proprietary dataset built from more than 10,000 expert-labeled products and more than 100,000 simulated examples, following an internally consistent methodology presented at Cosmoprof, AMWC, and Skin of Color Update. Levels from best to worst: Superior, High, Average, Low, Caution, Warning.

Behind these ratings: Nadia Kapleva, MS (Co-founder, Medical Director); Alexey Shagraev, PhD (Co-founder, CEO and CTO); Dr. Sofía Perea Pérez, MD, MSc (Medical Board); Aishani Shah, MD (Medical Board); Asya Zubkova, MS (Medical Board); Hanna Kurets, MD (Medical Board, Medical Advisor); Elina Nazarenko, MD (Medical Board); Victoria Derkova, MS (Medical Board).
