Probiotics are healthy for your belly and have now found their way into natural skin care products with kombucha, best known as a fermented flat self-reproducing mushroom-like tea, being used in various formula to help make you healthy.

On September 7, the wellness blog Well + Good NYC highlighted that kombucha tea's yeast, sugar and bacteria makes it the ultimate "it" ingredient for a healthy glow, firmness, balanced pH and anti-aging.

It is also believed that kombucha's internal healing powers extend topically to treat acne, psoriasis and dry skin.
