The Brow Soap features an exclusive formula containing bioactive ingredients with hydrating properties such as Hyaluronic Acid and Shea Butter. Brow Heist is one of the first Brow Soaps on the market to include Hyaluronic Acid. This particular ingredient means our soap is extremely nourishing as well as high-performing - the best of both worlds! The Soap is free from chemical nasties including Sulphate, Parabens, Phthalates, and Fragrance. As always, the formulation is vegan and cruelty-free.
