Good product part of daily face care.
I use this daily in my face routine. I like the feel of it and consider it a good product. My dermatologist recommended niacinamide for sun damage. I’m 79 and get comments on my great skin and few wrinkles.

Excellent for age spots/hormonal hyperpigmentaion.
It took me a while to like this serum because it is so sticky, and paired with other moderately sticky serums (like L’Oreal’s retinol serum), my face is even stickier. But since I use this only at night, I can overlook the stickiness and somewhat heavy feel after I top off with my night moisturizer. I love how soft my face is in the morning after I wash it with a gentle cleanser. I have aging skin that is slowly filling with spots and hyperpigmentation. This serum has helped a lot over the last four weeks, along with an arsenal of other actives, like Vitamin C, retinol, retinal, collagen, and peptides, put together in separate morning and evening skincare regimens. I’ve used other Cos de Baha products and like them all, this Niacinamide 20% being one of the main actives in my arsenal. No weird smell or funny texture, just a clean product that works. As far as this being a pore reducer, I cannot speak for that because I’ve had huge pores since birth and even lasers and microneedling at my dermatologist’s office haven’t shrunk them — my gift in the crapshoot that is genetics. My main problem now is the discoloration on my face that came after menopause, and this serum is definitely helping.

Works pretty good.
I have huge pores and can never find anything to minimize them, but with regular use, it reduces their size fairly well. I like how it's helps my "old lady" skin look and feel better. I am mostly satisfied with it's performance.

It's good
I love the product. The packaging is awful though. I put it in my skincare box and it got jumbled around and leaked out everywhere. Makes me wonder how fresh it's gonna stay if it leaked out with minor pressure out of the dropper top. I repurchased and I'm more careful now. The product itself is awesome. It's helped me with cold sores too moisturizing, doesn't take much. The ingredients list is nice. I'm a skincare addict so I'm always trying out new stuff. Just really disappointing packaging.

Improve pore appearance and skin radiance
I’ve been using this product consistently and I’m really impressed with the results. My pores look noticeably tighter, and my overall skin tone appears brighter and more even. The texture feels lightweight yet hydrating, so my skin stays comfortable throughout the day without any dryness or irritation. After finishing my first bottle, I can honestly say it has made a visible difference compared to other products I’ve tried. It works well under makeup too, giving my skin a smoother appearance. I’m very satisfied with this purchase and plan to keep using it as part of my skincare routine. Highly recommend it for anyone looking to improve pore appearance and skin radiance.

Great product!
I purchased this product based on reviews. It does not disappoint! It plumps up under my eyes and smooths out the fine lines and wrinkles. It is a bit thick but I use vitamin c first then this product and my moisturizer. It has made a difference and makes my makeup look smoother as well. Great product so far!

My dry skin loves this dewy glowy youth serum!
This serum is amazing. It has transformed my skin so quickly. I had been struggling with rebuilding my stratum cornium and lipid barrier after making some bad product choices and damaging my skin. I had this product for awhile and set it on my bathroom shelf because I read that it was helpful for oily skin. Well my skin is anything but oily. It's terribly dehydrated and uncomfortably sensitive. But when I learned that it helps build the lipid barrier and added it into my routine hoping it played nice with all my other products and helped hydrate my skin. Not drying at all. I'm on a strict routine of oil cleansing, tetrahexyldecyl ascorbate, stem cells and peptides, bakuchiol, hyaluronic acid, and lipid complex and this serum plays wonderfully and even compliments all these ingredients. I'm in my mid forties and I'm starting to feel like I'm in my thirties again. It's hydrating, it's gentle, it's protective, it makes your skin look amazing and glowy AND it helps rebuild damaged stratum cornium which is the real reason our skin ages.
