To moisturize the skin well, a closed film needs to be formed on the skin surface.No matter which moisturizing product you use, be sure to apply it evenly and thickly enough. You should apply more when applying it, and try to cover the skin completely.
There are usually three ingredients that can help moisturize the skin:
1.Oil: Applying a layer of oil on the skin surface can stably cover the skin and form a closed structure, which can largely prevent the moisture in the skin from evaporating outwards. At the same time, oil can also soften the cuticle.
2.Hydrophilic polymers: Some hydrophilic polymer components, such as hyaluronic acid, collagen or polysaccharides, can also reduce water evaporation when applied to the skin surface after absorbing water.
3.Water: The optimal water content of the stratum corneum is 10% to 30%. Applying water on the surface of the skin can also make the stratum corneum absorb water and soften it, retaining the water in the skin. Therefore, applying some moisturizing products with high water content will also have a certain effect.
