Allies of Skin Prebiotics & Niacinamide Pore Refining Booster: 10% Niacinamide, Goji Berry, Lysophosphatidic Acid. Pore Reducing Serum. Firms & Brightens. Strengthens Skin Barrier 1.7 oz / 50 ml

Since I was unable to get this from other sources, I am glad I found it on Amazon. Product was shipped promptly, arrived in perfect condition. Product is scentless, which is perfect for me, I am sensitive to perfumes and that shouldn't be on my skin anyway. I do feel my skin looks better after a month of use, less redness and healthier looking.

Si applica prima della crema idratante e si asciuga velocemente

Delivers a punch more of skin friendly pre and probiotics and green tea extract/goji berry extract. Switched over from the Paula’s Choice Niacinamide for this reason. Bottle cap is easier to use for liquids.

Will purchase again and again

I was so surprised to see negative reviews of this product. I think it is awesome! I have been wanting to try a high-quality Niacinamide serum for my blotchy skin and also some dark spots that have been starting to appear on my face the last few years. I am impressed with the ingredient list. Niacinamide is the 2nd ingredient on the ingredient list, so this is the real deal! It also has some amazing herbal and fruit extracts along with silver and hyaluronic acid, all of which are super-benificial to the skin. This is a liquid consistency and it goes on very smooth without any stickiness. It has just a slight earthy, medicinal scent, but many people will find this unscented. I love that there are no artificial, synthetic perfumes. So many face products are over the top with stinky perfume, but this has almost no scent which is really important to me. Regarding flushing that one reviewer mentioned (and gave this a poor rating). I tend to easily flush and I have had absolutely no flushing issues. This is made with Niacinamide, not Niacin. Niacin will cause flushing, but Niacinamide does not. This is not a strong or acidic product, so there would be no reason for flushing as that one reviewer mentioned. There is absolutely no stinging or strong feeling on my face using this product. Another reviewer said this left them greasy and shiny. I don’t know why they said that, because this is absolutely not a greasy product. The consistency is very water-like and dries to a matte finish, so I have no idea why they would say this is greasy. Another reviewer said they are not seeing results with this product. It is well-known that seeing results from Niacinamide takes at minimum 2 weeks, but can take up to 4 weeks. It is not going to “instantly” fix your problems, but with dedicated daily usage, you will see a difference. This is a big bottle and you only need one squirt from the pump bottle, so this bottle definitely lasts along time. This product is made in the USA which is really important to me. I have tried some face serums that I found out were from Korea and I was not satisfied with them because of some weird ingredients and strange scents. I trust this company because they are USA-based. I think the $65 is very reasonable for a super high-quality Niacinamide product. I am confident I will start seeing results in 2 weeks based on everything I’ve read about Niacinamide. This has 10% Niacinamide, so it is some of the best available on Amazon. I am 100% satisfied so far with this product!
