I have oily skin and like using it in the morning as it helps to significantly reduce how oily my skin feels during the day. My makeup looks so much better with it. I also notice that my pores stay cleaner for longer, which is great. It’s supposed to help with strengthening the skin barrier and healing, which I believe it does, however I usually layer several products with it, so I can’t say how well it works on its own. I’ve tried different Niacinamide serums form other brands, but this one seems to work best for me. Definitely worth the money, highly recommend!

When I looked into it, the active ingredient was niacinamide, so logically I jumped on Amazon to see if there was a similar product without the astronomical price tag...this is it! I’ve been using it for about two weeks now and have noticed a subtle but definite difference in my skin. It appears to work and I am happy. I have sensitive skin and this product didn’t irritate. ## Frequently Bought Together - Niacinamide 10% + Zinc PCA 1% Serum for Face - Pore Reducer + Uneven Skin Tone Treatment + Diminishes Acne Prone, Skin Balancing Pore Reducing, Restores Elasticity, 1 Fl Oz (30ml) - Pure Hyaluronic Acid 1% Serum 10,000ppm - Hydrating Face Serum for Fine Lines - Intense Moisture Facial Serum for Visibly Plumped Skin, 2 Fl Oz (60ml) - Vitamin C 15% Serum with Arbutin for Face - Brightening Facial Serum with Aloe - Professional Formula for All Skin Types, 1 Fl Oz (30ml) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/83760570-cos-de-baha-niacinamide-10-serum-30ml-tightens-pores-reduces](https://www.desertcart.jp/products/83760570-cos-de-baha-niacinamide-10-serum-30ml-tightens-pores-reduces) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-22*
