Almost 1.618 - danaida review for Niacinamide 5% Monoserum

I was looking for a niacinamide product that contains less than the standard 10%, because I read that lots of people have bad reactions of it. Niacinamide is effective from 3-4% and this one have 5% with a simple but great INCI, so I picked it. It comes in a simple but nice packing with a brown glass, and also the dropper works well. I was careful initially (I used 2 drops with no other ingredients that can be irritating). It has no smell, and it's alcohol-, fragrance- paraben- and silicone-free. The texture is lightweight, watery and it absorbs really fast to my skin, leaving a smooth and softer skin right after using it. I had absolutely no irritation, bad reactions or purging, but a much better skin overall after a few uses. I have been increased the frequency, because my skin seems loving it. It works well with my other serums and products, both in my AM and PM routines. All in all it's my essential fighter against blackheads and oiliness. Less is more in regards of this: Almost 1.618's niacinamide is perfect for those who wants to try niacinamide but have some fears or a bit more sensitive skin. I'm quite sure I will repurchase it (and not planning replacing or upgrading to a higher %), as this seems the perfect nia for my skin.
