It is said the Cleopatra bathed in milk to keep her skin soft and supple. Although it seems weird to soak in milk it is actually great for the skin. The lactic acid in milk contains alpha hydroxy acids, which work mainly as an exfoliate, encouraging dead skin cells to slough off making room for new skin. Milk can cleanse the skin down to its deepest layers.
Although, Cleopatra reportedly used sour milk, you can use regular milk or buttermilk instead. Just add 2 to 4 cups of fresh milk or buttermilk to your bathwater as the tub is filling. You could even use powdered milk if that seems more bath-like to you. Soak for a good 20 minutes. Shower to rinse and use a sugar scrub or shower gloves to help remove the old skin. Keep the shower water on the cooler side, since the hotter the water the harsher it is on your skin.
Fit's Tip: If you are lactose intolerant or straight up allergic to milk, this is not a home spa treatment for you.
