The winter can wreak havoc on our skin. With cold, wind and the low humidity caused by winter heating, it's hard to keep your skin hydrated. Drinking water helps, but when the climate conspires against you, moisturizer is your best friend. Moisturizers are comprised of two primary components: Humectants (like propylene glycol, hyaluronic acid and PCA), which draw water to the skin, and Occluisve agents (like petroleum jelly, oils and waxes) which form a barrier to prevent water loss. A well-balanced moisturizer contains both, along with other emolients and ingredients to make them smell and feel good, while acting in concert to hydrate your skin. The Ultimate Hydration Kit is a collection of six of my favorite hydration products, designed to keep your skin hydrated from head-to-toe. Normally $44, it's on sale this week for $29, including free shipping when you order it from the Washtub Spa "Shop Now"page on facebook. Friend the Washtub Spa, and save an additional 10%!
