Ceramides and glycolipids are naturally occurring skin lipids, a layer of natural protective fats that are abundant in a newborn baby’s skin, but are diminished by sun exposure and time, and by extensive exfoliation. For the best anti-aging and hydration, I recommend incorporating a product with these into your daily regimen.

Lipids can keep your skin hydrated, and looking younger. However, they are not absorbed into the dermis; instead, they sit on the top layer of the stratum corneum and protect it. from water loss and the appearance of dry wrinkles on the skin.

Many factors are responsible for depleting natural skin lipids. All methods of exfoliation, where we are accelerating the loss of the dead cell layer, resulting in less skin lipids. A drier climate, or even just the dryness caused by a dehumidifier or air-conditioning, will also lessen skin’s natural lipid compliment. As we age, skin lipids lessen. I recommend replacing them once you have reached your early twenties.
