nice product but very thick if you do layering of other serums
Its a great product, I love most of Cos De BAHA products.. I can't live without their 10% Niacinamide so when I saw they came out with a 20% I was excited. The 20% is VERY thick a different consistency than the 10%. I layer a lot of serums so for me I don't like this b/c it takes 40 mins for it to absorb .. this would be a good product if you weren't using other serums or if you use this one last but I apply according to ph so it's not going to work for me and I won't reorder it. I will be reordering the 10% though and I do still like the 20% so I will use it up...it is a very nice product.
