Science
Mechanism of Action
Hydrolyzed Jojoba Esters integrate seamlessly into the skin barrier, mimicking human sebum due to their unique molecular structure, which effectively reduces transepidermal water loss (TEWL). The hydrolysis process creates smaller, more water-soluble molecules that improve skin penetration and moisture binding. They actively support barrier function, help soften skin, and are believed to trap glycerin molecules at the skin's surface to significantly increase and extend moisturization. Rich in fatty acids, they also nourish the skin and provide antioxidant protection against environmental stressors.

Safety
Safety Profile
The independent Cosmetic Ingredient Review (CIR) panel has concluded that jojoba oil and its esters, including Hydrolyzed Jojoba Esters, are safe for use in cosmetics. They are considered non-toxic, non-irritating, and non-sensitizing. The large molecular weight components are not expected to penetrate the skin significantly, and their use is also permitted under European Union Cosmetics Regulation.
