Abstract
Little is known about the absorption of topical drugs in epidermal disease associated with epidermal proliferation and altered keratinization. An abnormal hairless mouse epidermis was produced by 3 different methods: UV light irradiation, topical vitamin A acid and topical acetic acid. An increased epidermal thickness resulted and the in vitro percutaneous absorption of 0.1% (4-14C) hydrocortisone increased when compared with normal hairless mouse epidermis. This is evidence for defective skin barrier function in experimental epidermal disease.
