Review: 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.
Review: 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.

**Q: How does it help skin?**
A: Brightens the overall look of your skin.

**Q: Sirve para piel grasosa?**
A: Si, de hecho yo tengo piel grasa y me trabaja muy bien

**Q: Can you use this in a micro needle vial, or is it too powerful?**
A: Per directions, apply this product to chin or neck to do a patch test to make sure you have no allergic or harsh effects. If not, I'm sure you can use this serum with the micro-needling. Anytime you perform the micro-needling it's very beneficial to have a serum to protect the skin from needle entry and of course to let your favorite serum penetrate the skin.

### ⭐⭐⭐⭐⭐ Best Quality on Amazon
*by J***N on May 20, 2025*

I’m a researcher and have devoured information on niacinamide. I’ve researched the products available on Amazon and have found this to be the very best one. I’ve had no irritation whatsoever. I do blend it in with snail mucin, which delivers amazing results. It’s excellent value for money with a consistency you would expect with high-quality niacinamide. Great value for money no sense. I’ll continue to buy this product for as long as it’s made available.
