Cos De BAHA (TN) Tranexamic Serum

Cos De Baha tranexamic and niacinamide serum 8/10- I know niacinamide is in everything these days which sucks for people that are sensitive to it, but my skin loves this stuff, the consistency is pleasant and sinks nicely into the skin, too much can leave a sticky feeling. it works well on my hyperpigmentation but its very slow and I'm impatient, lol. I actually thought it wasn't working until I looked at my progress photos and there's definately a big improvement on my hyperpigmentation. will repurchase

To this day, the ONLY products that have noticeably faded my PIH are Rohto Mentholatum Melano CC and now.... Cos de Baha Tranexamic Acid serum!

It's been 2 months since I bought this. I admit that I wasn't using this consistently at first since I am using my other serum which is a repurchase (Axis-Y Dark Spot Correcting Glow Serum; both contains 5% niacinamide and I'm alternating them when I feel like it but majority of those times I use Cos de Baha). Last month I have been using this twice a day, everyday and as you can see I'm already halfway of the bottle. This one has low viscosity and it spreads easily. One drop for each cheek is adequate to to cover the forehead, chin, and nose areas. I also noticed that it hydrates my skin too due to the majority of the ingredients are plant extracts (even the first ingredient on the list is aloe vera). I don't need any additional hydrating ampoule/toner/essences. The application is sticky if you apply it to dry skin and it can take up to 10 minutes for the sticky feeling to fade. But if you apply it on damp skin (which I usually do), it's not that sticky anymore even if you let it dry. In terms of brightening, my dark spots (from my breakouts last May) have faded significantly (see attached pics) but not that completely, like 80% of it. Of course, brightening dark spots isn't possible without my weekly exfoliation session and SPF + umbrella. Fading dark spots really needs patience and consistency Status: HG 🥰

I am using this on my neck, chest, and back of hands (just started using tret on my face; not sure how this would act with that). One drop spreads easily. I think this IS lightening some dark spots I had! I've only been using it for 3 weeks though. It doesn't irritate my sensitive skin at all. I already ordered another bottle because I think it actually is working. Worst case scenario is that it doesn't lighten the spots anymore; best case scenario is that prolonged use radically evens skin tone. The price point makes this investigation worth continuing, lol.

I have been using this regularly since April 2023 and just after the first couple of weeks I noticed improvements in my redness, hyperpigmentation and severity of acne flare-ups. I will definitely continue to keep this in my routine. I’ve emptied several bottles in the past year and change. In addition to using it on my face/neck, I’ve also used it to reduce redness from skin irritations on my hands, chest and back. Recently I had some broken blood vessels on my hand and the azelaic acid serum helped to reduce the redness to almost nothing in less than 2 days.

Cos De Baha is working well for me right now. It has Tranexamic Acid and Niacinamide!!

...and I pronounce this product my very first HG 🌟 I find this serum very simple and that's what I like about it : it's easy to use with other products, and I haven't encountered any problem. My skin has never reacted negatively to this product. It works the best on PIE and recent acne marks for me, especially if you use it while the acne is still active. It's also slowly getting rid of acne marks i got in September that had now turned into PIH (and oh I wish I had it back then...!) It's very affordable and one bottle of 30ml lasted me 3 months and 25 days for a daily use twice a day. I can not see my routine (or even my life!!!) without this product now. My rating : 5/5, i will keep repurchasing this !

I’m 6 weeks now and slowly trying to made adjustments to my skincare. I recently introduced the Cos De Baha Azelaic Acid which made a lot of the underlying bumps surface up, so I’m definitely dealing with an ugly purge but it’s definitely less painful this week. I had a horrible experience with The Ordinarys AA last year so I’m glad this one is so far okay with my skin.

I am a big fan! I’ve used it for, I think, 2 years now? I have stubborn melasma as well as age spots, and dry, sensitive skin. It helps me maintain progress between hydroquinone cycles, and might be helping a little with age spots (I use multiple actives so it’s difficult to pinpoint one). It certainly doesn’t hurt, and it’s an easy layer to add.

Same! It's also my HG. Turns out it's very versatile as it has worked for PIH, PIE and recently someone told me it helped tremendously for their rosacea. And i love that they come in 60ml as well.
