Humectant
An ingredient that draws moisture from the environment or deeper skin layers to the surface. Examples: hyaluronic acid, glycerin.
What It Is
A humectant is a type of ingredient in skincare products that helps retain moisture in the skin. It works by drawing moisture from the air or deeper skin layers to the surface, leaving the skin feeling softer and more hydrated. This can be especially helpful for dry or dehydrated skin.
How It Works
Humectants like hyaluronic acid and glycerin attract and hold onto moisture, allowing it to be absorbed by the skin. This process helps to lock in moisture and support the skin's natural barrier function.
Why It Matters
Understanding humectants is important for skincare research because it helps us understand how to effectively retain moisture in the skin, which can be a key factor in addressing dryness, irritation, and other skin concerns.
