Your grandma probably didn't worry about collagen treatments or the right antioxidant serums for her skin type, but she may very well have had glycerin in her medicine cabinet. So what's behind this impressive longevity in a field that's constantly evolving?
Simply put, glycerin is an ingredient that closely resembles your skin's natural moisturizing factor, or NMF. The naturally occurring chemicals of the NMF can absorb large amounts of water, even in low humidity environments. Glycerin, a humectant and an emollient, mimics that super-hydrating effect while smoothing your skin.
Not only does glycerin quickly hydrate your skin, there is also evidence to suggest that it increases your skin barrier's ability to hold moisture. In other words, glycerin can actually make your skin more resistant to future drying, more than almost any other ingredient!
So where can you find this wonder moisturizer? Many creams, lotions, and even soaps contain glycerin, and there's an option for every skin type and budget.
Wishing you great skin!
