The potent combination of 20% niacinamide and zinc PCA has worked wonders for my skin. Since using it, I've noticed a reduction in the appearance of blemishes and improved overall skin texture. I appreciate that it's fragrance-free and suitable for sensitive skin. Cos De BAHA consistently delivers high-quality skincare products, and their NZ Niacinamide 20 Zinc PCA is no exception. If you're looking to improve your skin's health

Another great serum from Cos De Baha: high percent Niacinamide and Zinc that helps with clearing and soothing the skin. I apply in the morning and in the evening on bare clean face and then follow up with other serums/moisturizers which are part of my usual beauty routine. The serum is a little sticky so I let it dry well for few minutes before applying any other products or make up. It comes at an affordable price compared to other high street brands that offer similar products at a much higher price. I have only started using this serum so I cannot comment on the long term effects but I’m looking forward to seeing good results over the course of the next few weeks. If my review helps, please kindly leave a thumbs up for me. Many thanks!

A bit hard for me to gauge how well this product has worked for me. I have been using it for over a month now I believe, and while I do not see any reduction in pore size (perhaps there is a very minuscule reduction but I can’t tell), but I have noticed a huge reduction of sebum production. I can not say if it was this product alone that reduced it so much because I am using it along with a few other skincare products that also have the potential benefit of sebum reduction. If it was this product alone that reduced the sebum so much it would be holy grail status product for me.

Doesn't irritate my sensitive skin and doesn't have a scent. I noticed it actually helps with my skin texture and clearing some small dots (pigmentation). My skin looks clearer and brighter.The 30ml package is quite small, but lasts for a while if used correctly
It's hard to find 20% niacinamide serum. If you do, it's often hard to get or very pricey. This product is neither!The serum is very thick and you don't need more than one drop to cover your whole face. It dries down quickly, is not sticky and plays well with other serums and make up. This is a must buy for anyone who wants a high percentage of niacinamide at a good price. Recommended!
I really like this serum, Niacinamide 20%, Zinc PCA 4%, Arbutin, Hyaluronic Acid and Natural Herb Herb Extract as active ingredients. I use my morning and evening skin routine. My pores got smaller, and my mature skin smoother, this is my 1st bottle to try, I'm already finished half of the serum, and I have already purchased a backup. I tried other brands as well, but the bottle's quality and design were much more manageable than other brands, and less waist serum.
Compared to The Ordinary Niacinamide Serum, I very much prefer Cos De Baha version. The main ingredients in this serum is aloe leaf extract (very hydrating) instead of water like in The Ordinary serum. Both serum has zinc pca (reducing redness and breakouts). Cos De Baha serum has additional beneficial ingredients such as sodium hyaluronate (humectant), allantoin (skin-softening, promote wound healing), licorice (soothing, anti-inflammatory, sebum regulating). You won't find this in The Ordinary version. The prices for both serum are comparable but we get a more comprehensive formulations with Cos De Baha. I pair this up with the BHA 2% salicylic serum and they work wonders for pore tightening. Our pore size cannot shrink but with the help of salicylic acid (deep ...

I pair this up with the BHA 2% salicylic serum and they work wonders for pore tightening. Our pore size cannot shrink but with the help of salicylic acid (deep clean excess oil out of pores) and niacinamide (tighten pores), pores may return to their normal size. I tried both the 10% and 20% niacinamide and i find 20% is more powerful for my oily-large pore skin. The 20% version does not irritate my skin. However, for normal to dry skin people, 10% may be sufficient. If you have oily skin or skin with enlarged pores, you must include NIACINAMIDE 20% in your skincare regime 👍
I try to give products at least 3 weeks of use before reviewing them, but this gave such quick results I think it's fair to review after 1 week. It brightened my post blemish marks and entire complexion noticably. My skin tone is already more even. I use it at night only, under a retinol moisturizer that I started 2 weeks ago. So that might be contributing, however the improvement really kicked into high gear within days of adding this to my night routine. I am very impressed and plan to repurchase. Its the 3rd high concentration niacinamide serum I have tried (The Ordinary & Cosrx, both very good) and Cos de Baha is definitely my favorite.

Its the 3rd high concentration niacinamide serum I have tried (The Ordinary & Cosrx, both very good) and Cos de Baha is definitely my favorite. The bottle is smaller than expected, but it's still a fair buy for the price. Be aware that it's rather sticky and viscous, almost like honey. Despite being prone to clogged pores, the texture does not bother me at all, but be prepared. The stickiness went away after I applied my night lotion, but I'm not sure if foundation would sit well on top of this. It spreads over skin MUCH more easily with a compatible essence underneath. It gives an extremely glassy finish, which I like. It did not clog my pores or dry my skin. I'm expecting it will prevent clogged pores but too soon to tell. I am thrilled with the combination of several actives and the listing of percentages. Please do not change or discontinue!
After years of using niacinamide, and using niacinamide products from this brand, I was confident I could use a 20% niacinamide serum. Unfortunately, I was wrong. I was disappointed to find this caused skin to peel in more sensitive areas (and my skin is pretty tough). So I don't recommend this, but if you have very resilient skin it may work for you
we all know we were a bit sceptical of cos de baha because of the packaging and prices. or is it just me ? cool? okay. so no. i got this instead of the tiam 21 niacinamide serum because its cheaper and had low expectations. but boy oh boy did it deliver. it snatched them pores tighter than i dreamed. and a little gies a long way truste me. why waste money on more expensive brands when this works just fine trust me. i will be seeing mir of this brand in my cabinet for sure
