The Spanish house founded in 1975 offers elegant moisturizers, advanced sunscreens, restorative serums, and targeted eye products featuring balanced formulas that suit dry and sensitive skin best, with standout solutions like Fusion Water, Eryfotona Actinica, and K-Ox Eyes. Meanwhile, the Indian label launched in 2018 is warmly embraced for sensorially pleasing sunscreens and lightweight textures that suit balanced, combination, and normal skin best, including the WATERMELON COOLING SUNSCREEN for acne-prone skin.
