According to Taishan Health Inquiry, probiotics are microorganisms that can help people maintain the balance of intestinal flora. They can maintain intestinal health by regulating intestinal flora and increasing the number of beneficial bacteria in human intestine. Probiotics also have a certain effect on beauty beauty, which can tighten the skin. Probiotics fundamentally improve skin quality by regulating intestinal flora. We know that the health of human skin is closely related to intestinal flora. If the intestinal flora is unbalanced, a series of problems will appear in the body. For example, if the body lacks enough flora to digest food, food will accumulate in the body, leading to intestinal corruption, which will not only lead to digestive system problems such as constipation and bloating, but also affect the skin. Probiotics can maintain the balance of intestinal flora, thus supplementing our intestinal flora. These probiotics can be supplemented and injected into the body by ingesting commercially available probiotic drinks or foods. In the process of intestinal flora regulation, they can stimulate cell metabolism in vivo, thus improving skin elasticity and luster and making skin firmer.
