Creases caused by dryness can have various causes and appear even at a young age. They indicate the presence of too little moisture in the upper layers of the skin. This can be caused by external factors such as UV radiation or cold weather, dry air or exhaust gases as well as by a loss of elasticity of the skin in the course of natural aging. Cosmetics with concentrated, intensive hydration can help against creases caused by dryness. Hyaluronic acid serums with low molecular weight hyaluronic acid are particularly well suited as they absorb into the skin and bind large amounts of moisture there. But plant saps such as aloe vera can also counteract dryness.
