Kiehl's - mrsmisselbrook review for Ultra Pure High-Potency 5.0% Niacinamide Serum

I really love this serum. It’s lightweight, simple and absorbs fast without leaving any tackiness. My skin feels more balanced and a lot less shiny during the day. I like that it only has 10 ingredients because it fits easily into my routine without clashing with anything else I use. It layers well under moisturiser and SPF and gives my skin a smoother, calmer look. If you want an easy everyday niacinamide that gets on with the job without any drama, this one is a great pick.
