Cheapest game changer I have in my brews!
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. ✨🔮

Best Niacinamide I’ve used!
I ordered this serum to help maintain the health of my skin as well as to help reduce sun spots and prevent new lines. I’ve been using Cos De Baha niacinamide for 6 weeks and I have noticed remarkable improvements. Here are the benefits I’ve noticed during more than one month of daily use: firmer skin, more hydrated, sun spots have considerably faded, face glows, pore size minimized, fine lines are less noticeable. I really love how this serum has improved every aspect of my skin and I enjoy looking in the mirror again. I no longer see dry skin with enlarged pores and sun spots. The consistency of this serum is perfect. It absorbs quickly but leaves a nice layer of hydration. It’s great underneath foundation, as it’s not oily or greasy feeling. This particular serum is potent and significantly helps to beautify and maintain the skin’s natural balance. In the beginning, I was unsure as to whether or not I should purchase from a Korean cosmetic company, but I’m completely satisfied with this brand and for the affordable price and excellent quality with natural ingredients, you cannot lose!

Miracles do happen!, but not for me.
I have never used any serum like this in my life! I am seeing a major difference in the texture of my skin in just over a week! Pores and dry “crinkles.” Dramatic difference! Even my dermatologist doesn’t even carry a serum as good as this! Thin,lightweight, soaks right in. Does not leave sticky film. Moisturize after...Not costly! Simply amazing! ......Came back to say I had to return my second order on this product. I started getting tiny hives on my face. Niacinamide is a form of niacin, which, you can get hives from. Just try in inconspicuous place first

This stuff really works!
I was searching for a niacinamide and zinc product as I heard the combination can help with breakouts. I was considering the ordinary's serum but this came up in my Amazon search and had great reviews, so I gave it a whirl. My breakouts are occasional and mostly hormonal along my jawline but I also have clogged pores along the sides of my cheeks. The night this arrived I patch tested a small amount on the left side of my cheek and woke up to perfectly normal skin: no redness, irritation or dryness. With the sign to proceed, I used a drop full on my entire face that morning and that night. Over the next few weeks of using this (which included international travel and travel for work, which is usually breakout city for me) I noticed no new breakouts along my jawline! I've continued to use this alongside my regular AM and PM routines and my skin has been consistently clear, soothed, dewy and nicely toned. Seriously, I haven't used pimple patches at night in a full week! This serum has no smell, spreads across my face easily, and sinks in quickly. I've already repurchased 2 bottles so I'm never without this. If you are considering this product, just buy it and give it a try!!

Good and not-so-good.
The not-so-good: It didn't reduce my pores. It doesn't help the oiliness of my skin. It doesn't lighten blemishes left by cystic acne breakouts. The good: It is moisturizing. It makes my skin soft even though it also makes my skin oily. Very sheer texture, goes on smoothly. It didn't cause any breakouts. Even though I will not purchase this again, I will not definitively say that it's not a good product. It has its merits. Unfortunately, it just didn't work as well for me as it has done with other users.

Great ingredients
I have been using this product for going on three weeks now. Long enough to know I like it, but not long enough to speak on the results. This is the kind of serum you have to consistently use to see improvements. Niacinamide is proven to brighten and even skin tone, reduce redness and scarring like PIH. I have PIH and redness from acne. I like that the first ingredient in this is aloe, not water. I also like that this has licorice extract. I got this as an alternative to the Ordinarys niacinamide +zinc serum. I like this better. The consistency is thin but not watery and absorbs easily. Does not pill. I usually mix three drops with my snail essence and apply after washing my face and using toner. I plan to continue using this and will update my review in about three months to report on the more long term effects. UPDATE: I finished the entire bottle bottle about a month ago. This little bottle lasted me a good 3 1/2 months. Since I've been out I've noticed my skin is just kind of dull and has been more oily. I feel like it's a staple in my routine now so I'm going to reorder ASAP. It helped fade some of my post inflammatory hyperpigmentation on my cheeks that had been there for 6 months. I really liked this product and totally reccomend it!

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.

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.

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.
