I used galactomyces essences before, so I knew, that my skin absolutely loves it. Now I was looking for a product with niacinamide in it, but not very low percent and also not very high. With 5% this product seemed perfect. Fortunately I received samples from Jolse, so I was able to test it out before ordering the full size bottle. It is really nice, absorbs quickly and perfect addition to a 10 step or 8 or 6... whatever :) routine.
