What is the function of humectants in skincare products?

Humectants play a crucial role in skincare products by binding with water and helping to draw moisture from the environment into the skin. This moisture-retaining ability supports skin hydration, making the skin appear plumper and healthier. When humectants are included in a formulation, they effectively work by attracting water molecules, which is essential for maintaining the skin's moisture balance and preventing dryness. This property is particularly beneficial for products designed for hydration, as it ensures that the skin remains supple and hydrated over time.

While preventing moisture escape pertains to occlusives that create a barrier on the skin, and soothing effects are typically a characteristic of emollients or calming agents, humectants specifically focus on water retention and moisture enhancement. Likewise, enhancing fragrance is relevant to aromatic compounds in skincare rather than the functional role of humectants.
