TL;DR: It is an amazing first treatment essence, I feel products I use after penetrate better the skin and it has slightly brightening effect. You need to use it constantly for a few months to see any significant results though.
šš¼ Packaging, texture, fragrance: It comes in a sturdy, glass bottle. Feels heavy and expensive but it's not very travel friendly. The texture is like a "fat" water, it is quite watery but also has some body to it. It has no fragrance.
šš¼ My experience: I love this FTE. I feel that the products I use after it work better. It has slightly brightening effect. With constant use I feel that my face is slightly firmer and brighter. The secret of ferments in skincare is that they need time to work and for you to see any visible results. Use it constantly and you will get that glow šš». I use it day and night, you don't need much to spread it on the whole face so a bottle will last you around two months.
