The American line from 2019 is widely loved for its serums, moisturizers, eye products, and exfoliants formulated with glycerin and hyaluronic acid, suiting dry and acne-prone skin best. Meanwhile, the other maker is appreciated for its nourishing masks and delicate formulas suited for dry, oily, and combination skin.
