The Korean brand is adored for harnessing hyaluronic acid, glycerin, and niacinamide to suit acne-prone and oily acne-prone skin best through standout items like the Advanced Snail Mucin Gel Cleanser, the Full Fit Propolis Synergy Toner, and the Centella Water Alcohol-Free Toner. Meanwhile, the Spanish brand is beloved for advanced serums and active compounds that suit sensitive, hyperpigmented, and aging skin types best with standout products like the Azelac RU Serum.
