A top Japanese (SK-II) fermented essence and three popular Korean ones (Secret Key, Missha and Monique Labs). These all use fermented rice products, all but Missha using galactomyces fermate filtrate. Which do I like best and why?
Also, what are the benefits to skin? In short, they refine and even skin tone, deal with both dryness and acne, reduce visible pores and minimize the effects of aging. I love them.
Another I like, NoTS Aqua Softener, also uses fermenting ingredients but not fermented rice. So while it's mentioned in the video it isn't discussed in as much detail.
