What ingredient is known for softening the skin and acts as a humectant?

Glycerin is well-known for its ability to soften the skin and functions effectively as a humectant. A humectant is a substance that helps to retain moisture in the skin, drawing water from the environment and deeper layers of the skin to keep it hydrated. This characteristic makes glycerin particularly beneficial in skincare formulations, as it enhances the skin's hydration levels and contributes to a smoother, more supple appearance.

In addition to its humectant properties, glycerin helps to strengthen the skin's natural barrier, reducing transepidermal water loss and improving overall skin texture. This is especially important for individuals with dry or dehydrated skin, making glycerin a staple ingredient in moisturizing products.

While sodium hyaluronate is also a powerful humectant, it is derived from hyaluronic acid and has different characteristics in terms of its molecular size and absorption properties. Lanolin and shea butter, on the other hand, are primarily emollients, which help to soften and smooth the skin but do not function as humectants in the same manner as glycerin does.
