A rich source of calcium and protein, milk usually features on the A-list of healthy foods for many of us. But if you are wondering whether milk can double up as an ingredient in your skincare routine, you are on the right track! Milk, especially when it is raw and unpasteurized or slightly fermented or sour (think buttermilk), can help your skin in many ways.
With age, not only do fine lines and wrinkles make their presence felt but your skin also becomes thinner and less firm. But sometimes, this skin aging takes place ahead of its time, due to factors like poor skin care or excess exposure to the sun. But the goodness of milk can help you fight these signs of skin aging. Milk contains an alpha hydroxy acid known as lactic acid that can boost skin health. According to one study, when participants used lactic acid on their skin twice a day for 3 months it reduced the appearance of wrinkles and lines, made skin smoother, and improved its firmness and thickness. Since lactic acid is formed when milk is fermented by bacteria, apply raw or slightly sour milk to make the most of this beneficial effect.
