A milk bath is a bath where you add milk — in liquid or powdered form — to warm water in your bathtub. It may be beneficial for a number of skin conditions including eczema, psoriasis, and dry skin.

Dry Skin

If you live with dry skin, milk baths may help replenish lost moisture. Milk contains:

Proteins
Fat
Vitamins
Minerals
Lactic acid

The proteins and fat may help soften and soothe the skin. And lactic acid is a gentle exfoliator. Exfoliation is important for shedding dead skin cells, which can lead to softer skin.
