Aloe vera as a cosmetic ingredient has many forms and not all are suited to facial cosmetic use. Avoid aloe vera leaf exudates which generally contain several components that cause skin irritation and erythema (redness). Aloe vera gel however is commonly used in after sun products to soothe the skin. The gel and its powdered derivative forms once hydrated in cosmetic formulations such as emulsions, micellar waters and toners provide a rich source of moisturising, water-loving polysaccharides. Its structure forms a protective film for the skin, which aids protection of the epidermis and the skin’s ability to restore itself. Aloe vera gel comprises also vitamins, amino acids, minerals and enzymes, which provide its skin-soothing effect.
