Cos De BAHA Niacinamide 10% Serum 30ml - Tightens Pores, Reduces Wrinkles, Repairs Skin, Vitamin B3

This stuff is great, very good quality, very good value, really helped improve my skin

Very pleasant, silky texture, excellent spreadability (1-2 drops are enough to cover the whole face), absorbs quickly, doesn't conflict with other skincare and make up products I put on top of it. Helps to calm down my acne prone skin. Updated: visible positive results started after about 5-7 days and I still enjoy using it 3 months later. Definitely less obvious pores, less redness and overall smoother, nicer skin :)

I bought this product after seeing an advert on Facebook for an amazing serum that would get rid of sun damage. 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.

I absolutely love this product! I bought it in August and used it every day! Such a soft, smooth, oil free texture! It fades dark marks and plumps the skin! I have very oily skin so that is why I went for this product and it didn’t break me out. It lightens the skin so only use it on problem areas. I’m annoyed now as I tried to get another one and they are currently out of stock.

Nice list of ingredients and lovely consistency when you first put it on. Unfortunately it doesn't play ball with my other serums and tends to pill.

Love it. Light serum, sits well on the face. Been using it for about a week and can already see pores sizing down. I hope my sun spots will also be effected soon! Definitely recommend.

Thankyou for my product,I have only been using less than a week but I like the way it smooths my skin and absorbs quickly.

Unfortunately this product did not agree with my skin which became very dry and irritated so I stopped using it after three days.

Es ist sehr leicht und flüssig, fast wässrig, die Textur ähnelt der von Essences. Das 30ml Serum hat mir bei 2x täglicher Anwendung (2-3 Tropfen) für 3 Monate gereicht! Ich habe eine empfindliche, unreine Mischhaut und hatte überhaupt gar keine Irritation davon. Am besten trägt man es nach einem Gesichtswasser oder Toner. Somit kann es am besten in die Haut eindringen und die Wirkung der Inhaltsstoffe ist viel effektiver. Da ich viele andere Kosmetiker mit Niacinamid benutze, kann ich nicht so wirklich feststellen in wie Weit das Produkt meiner Hyperpigmentierung geholfen hat, die Haut ist jedoch auf jeden Fall heller geworden und die Poren wurden verringert! Ich persönlich werde das Produkt wahrscheinlich nicht mehr kaufen, da ich noch viele anderen Seren ausprobieren möchte und ich nur neue Sachen kaufe, wenn ich die, die ich bereits benutze, aufgebraucht habe. Das Serum kann ich jedoch auf jeden Fall weiterempfehlen.

Sometimes the simplest spells are the most powerful. I wish I had found this straightforward, no-frills serum sooner — because this little potion has already done more for my oily T-zone, clogged pores, and dull patches than half the flashy brews in my cabinet. 🧪 Cos De Baha’s Niacinamide 10% + Zinc + PHA is one of those formulas that doesn’t try to impress you — it just works. It’s affordable, sleek, uncomplicated, and somehow still manages to make my skin look smoother, more refined, and a touch brighter after just a few uses. 🌬️ It layers beautifully — no pilling, no stickiness, no chaos in the mix — making it perfect for a witch who loves to mix and layer her elixirs with ritual-like devotion. 🌙 The Results (so far): I’ve only had her a short while, but I’m already seeing real changes in my texture and clogged pores. She calms the oil, brightens just enough, and sets the perfect tone for the rest of my potions to do their work. 🖤 Not the only Cos De Baha product on my shelf — but definitely the one that’s quietly winning me over the fastest. Sometimes the magic is in the consistency, the clarity, the quiet glow. This is that kind of magic. ✨🔮

I just received it. Was well packed and it looks ok. What does actually really botther me and people do need to know is that the bottle is not filled with serum. It's just above the half of the bottle. Don't know why and I hope at least it will help. I will leave this review open. 4 stars for now. I will give 5 if the product works and less if not.

Good product for a low price

A simple vista parece que ofrece lo mismo que el serum de The Ordinary, pero no solo tiene una textura completamente diferente: es menos denso, se absorbe con mayor facilidad y trabaja bien con otros productos en la rutina.. Sino que también tiene mejores ingredientes además de los activos como: aloe, allatonin, extracto de tomillo, entre otras cosas. Acabo de volver a comprar otra botella, me duro un mes y medio utilizando como 4-5 gotitas en la mañana y por la noche, sí note una disminución en las marcas rojas que tenía en la cara, en la textura general de la piel, y también en la reducción de unas líneas que me estaban empezando a aparecer en la frente por fruncir la cara al manejar. La experiencia de este producto además de los ingredientes sí justifican para mí comprar este en vez del The Ordinary.
