Moisturizers are designed to reduce water loss from the epidermis (the outermost layer of the skin). Basic essential components of moisturizers include emollients and humectants. Emollients provide a soothing protective film by filling-in spaces between cells and restoring lost lipids to prevent transepidermal water loss. Commonly used emollients include animal oils, butyl stearate, cocoa butter, lanolin, various lipids, mineral oil, petrolatum, and shea butter. In addition to preventing further dryness, emollients contained in moisturizing products provide a barrier against pollutants and dirt, improve the texture, and give a smoother appearance to your skin. Humectants aid in the absorption and retention of moisture, as well as soften thickened skin. Commonly used humectants in skin care products include glycerin, hyaluronic acid, lactic acid, propylene glycol, panthenol, silicones and urea. The effectiveness and suitability of these ingredients depends upon your skin type, so make sure to sample new products on a small area first before general use. A simple and easy way to restore daily hydration to your face is to apply a suitable nighttime cream just before going to bed. This allows time for absorption of the active ingredients – your body rejuvenates itself during this crucial restful phase, so it’s an ideal time to nourish your skin. Look for a night recovery cream with an amino peptide formula that has a time released effect. The beneficial effects will be clearly noticeable in the morning!
