Abstract
Abstract Novel tocopherol derivatives useful for regulating skin aging and other skin disorders, as well as compositions containing the derivatives and methods for their use are described. The tocopherol derivative is tocopherol-cysteamine. Such types of skin atrophy to be treated the thinning of the epidermis and/or general degradation of the dermis often characterized by hyperplasia and structural disorganization. Such skin maladies include but are not limited to dry skin, severe dry skin, terosis, dandruff, keratoses, psoriasis, eczema, pruritus, age spots, lentigines, melasmas, wrinkles, blemished skin, hyperpigmented skin, hyperkeratotic skin, inflammatory dermatoses and age-related skin changes.
