This is how you can use milk on your skin

Milk proteins offer remarkable moisturizing and nutritional properties. Their moisturizing capacity is a result of their excellent absorption by the skin, as well as their ability to bind water. These characteristics promote the creation of a hygroscopic film in the stratum corneum of the skin. At the same time, milk proteins release specific amino acids, which are very important components of the skin's natural moisturizing factor and have a nourishing effect.
There are many ways to use milk.
For example…. 
1. Make a glow compress
Fill a bowl with ice-cold milk and soak a new, soft kitchen sponge in it. Wring out the sponge and run it over your face for five to ten minutes, dipping it back into the milk during the process. Gentle acupressure helps reduce swelling.
2. Relieve dry, dehydrated skin
A bath in milk works wonders. Fill your bathtub with warm water and add half a liter of whole milk. Soak in for 15 minutes.
3. Relieve a sunburn
If you have a burn, soak a small one in a bowl of ice-cold whole milk and apply it to the burn until the towel comes to room temperature.
