Humectant Ingredients

Beta-glucan is a polysaccharide sourced from oats, yeast or mushrooms that works as a powerful humectant and soother. It forms a light film that locks in moisture and supports the skin barrier. It is sometimes compared to hyaluronic acid, but it is more calming.

Betaine is a natural humectant often derived from sugar beet, and one of the osmolytes that help cells maintain water balance. It is a gentle, versatile ingredient that hydrates skin and improves a formula's feel.

Collagen is the key protein that gives skin its structure and bounce, and it is added to products in a hydrolyzed form as a moisturizer. Its molecules are too large to reach the deeper skin, so topically it acts as a hydrator and water-binding film rather than replacing your own collagen. It leaves skin soft and looking plumped.

Ectoin is a cell-protecting molecule made by bacteria that survive in extreme environments, now produced biotechnologically for skincare. It works by forming a protective water shell around cells, shielding them from dehydration and environmental stress.

Glycerin is a simple, reliable humectant that has been in good moisturizers for decades. It draws water toward the outer skin layer and helps the skin hold on to its own moisture.

Honey is a natural humectant that draws moisture into the skin, with soothing and mild antibacterial properties. Varieties like Manuka honey are especially prized for calming skin and supporting healing.

Hyaluronic acid is a moisture-binding molecule that occurs naturally in the skin, acting like a sponge that pulls water into the upper layers. A single molecule can hold many times its weight in water, giving skin an instant plump, cushioned feel.

Panthenol is the precursor to vitamin B5, converting into pantothenic acid once it sinks into the skin. It works as a humectant that draws in water while helping reinforce the moisture barrier. You'll find it in soothing creams and hydrating serums because it's exceptionally gentle.

Polyglutamic acid is a strong humectant derived from fermentation, said to hold many times more water than hyaluronic acid. It forms a moist film on the surface that slows water loss. It gives an instant feeling of softness and plumpness.

Snail mucin, or snail secretion filtrate, became a K-beauty star for its dual power to hydrate and repair. It's rich in hyaluronic acid, glycoproteins, and peptides that heal skin and smooth its texture. Its slippery texture draws in water and leaves skin plump.

Tremella mushroom, also known as snow mushroom, is a powerful plant humectant that works much like hyaluronic acid. Its smaller molecules help it penetrate the skin gently for deep hydration.

Urea occurs naturally in the skin as part of its natural moisturizing factor. At low concentrations it acts as a humectant that draws in water, while at high concentrations it exfoliates and softens rough skin. This makes it common in face, body and foot care.
