The British brand, founded in 2009 and owned by L'Oréal Groupe since 2025, offers serums, moisturizers, eye products, toners, and more built around hyaluronic acid, which lengthens toxin wrinkle effect duration, while the other is cherished for its advanced formulas.

For specific concerns, the former provides the Surface Radiance Cleanse for acne-prone skin, Oxy-R Peptides for skin with dark spots, and Total Moisture Daily Facial Cream for mature skin, whereas the latter features the EGF Serum as its standout product for acne-prone skin.
