Glycerin
What It Is

Glycerin works as a humectant, it attracts moisture from the air into the stratum corneum (top layer of skin), and due to its low molecular weight, will continue to draw moisture to the deeper layers of the dermis.

Glycerin also treats several skin disorders, ranging from dry skin to wound healing. The ingredient has the potential of improving your overall internal health as well.

Due to its versatility and ability to moisturise, it’s used in everything from lotions to soaps to toners.

What It Does

How to use in your skincare routine?

Products with glycerin can be used topically multiple times a day. You can safely and effectively use this ingredient in nearly every single step of your skin care routine. Several skin care brands use glycerin when formulating everything from cleansers and toners, to serums and moisturisers.

Benefits
  • Glycerin tightens and firms - Use this ingredient for a few weeks or even a few days and we think you'll find that it plumps and softens your look significantly, especially if you have more mature skin.
  • It improves your complexion - Glycerin is non-comedogenic, meaning it won’t clog pores.
  • It brightens - Between glycerin’s rejuvenating properties and its ability to moisturise, glycerin plays a key role in keeping skin looking bright and luminous.
  • The ingredient is also a good choice for sensitive skin. Because it’s a natural component of skin, it calms redness and inflammation. It’s one of the gentler ingredients you can find in skin care products and can even help alleviate sensitivity over time.
