Myristyl nicotinate (Tetradecyl nicotinate) is an ester prodrug and a lipophilic derivative of Nicotinic acid. Myristyl nicotinate is being developed for delivery of Nicotinic acid into the skin for prevention of actinic keratosis and its progression to skin cancer. Myristyl nicotinate shows to stimulate epidermal differentiation in photodamaged skin, increasing skin NAD content and strengthening the skin barrier^[1][2]. In Vitro: Myristyl nicotinate (Tetradecyl nicotinate) is used for treatment and prevention of conditions that involve skin barrier impairment such as chronic photodamage and atopic dermatitis or for mitigating skin barrier impairment that results from therapy such as retinoids or steroids^[2].
