The Korean brand is adored for its serums, moisturizers, cleansers, and masks harnessing hyaluronic acid, glycerin, and niacinamide to suit acne-prone and oily acne-prone skin best, while the Indian brand is warmly embraced for its sensorially pleasing sunscreens and calibrated formulas suiting balanced, combination, and normal skin best.
