Meet hyaluronic acid’s moisture-boosting counterpart, glycerin. If the former is a freshman, the latter is a senior because it has been a part of some of our favourite skincare products for quite a few years now. Easily absorbed into the skin, this molecule goes beyond just the superficial effect of hydration and actually adds moisture into your skin and helps retain it, too. Plus, it is very soothing for sensitive skin. Pro tip: Is your skin extra dehydrated? Combine both hyaluronic acid and glycerin for the ultimate hydration and moisture boost!
