Soy milk is a type of milk derived from the soybean plant. Because it is plant-based, it doesn't contain lactose. This makes it an effective alternative for vegans or people who are lactose-intolerant. Additionally, soy beans and soy milk are significant sources of protein, which is a much-needed nutrient for good health, particularly for the hair and skin.
Protein provided by soy milk keeps skin tissues moisturized, and also increases their elasticity as well.
