Shine free
Bought this and used it instead of other brands I had previously used. I noticed a difference straight away and within a few weeks my shine had gone and blemish free. Will buy again

Simple Niacinamide Serum
This Serum is excellent for calming and improving skin texture. It’s lightweight, absorbs quickly, not sure if it works effectively but try to keep using it for my skincare routine

Not what I hoped
Sadly I’ve been using the product daily for approx 3 weeks and I’ve broke out on my forehead with two massive spots, which I’ve never had a problem with before. It ever so slightly helped with my oily t-zone but not very much, I’m afraid.

Disappointing
Was hopeful for this, but after three weeks of using, it's made me come up in pimples, so back to The Ordinary's Niacinamide for me, which I've been using for years
