This is my first time trying a fermented product and so far so good! I was a bit worried because I know that some people have an allergy to fermented ingredients. This biphase product is amazing. Its super fun to use as you get to shake it each time. The texture is light and moisturizing but not greasy. It sinks into the skin really nicely. My sensitive rosacea prone skin seems to be loving it. I think this is my first ever holy grail product. It makes my skin feel great and its super fun to use! Definitely will repurchase!
