What is Moisturizer?
Moisturizers or emollients are complicated mixtures of chemical agents specifically designed to make the external layers of the skin softer and more flexible. These chemical moisture agents can be man-made in a laboratory or naturally occurring plant extracts.
They increase the skin‘s hydration by reducing moisture evaporation. Naturally occurring skin lipids (fatty acids) and sterols (waxy solids), as well as artificial or natural oils, humectants (wet molecules), emollients, lubricants, etc. , may be part of the creation of skin moisturizers.
