This stuff really helps with melasma.
I've been using this TXA acid for a little over 2 weeks now and I love it. I've been using it twice a day and I'm already seeing results on the melasma areas on my forehead. I can't even begin to explain how genuinely thrilled I am about this because I've struggled to deal with that, and other hyperpigmentation, for years. The serum consistency is lightweight. I use several drops for my whole face. It also absorbs easily. I noticed that this serum can feel a bit sticky but I've figured out that if I use it directly after my hydrating toner, like while my face is still wet, it mitigates the stickiness of this serum completely, without preventing it from doing its job. It also helps spread the serum more easily.

Worked almost instantly for my PIE
I bought this for the redness and hyperpigmentation on my cheeks. People said it works fast, but mostly for melasma or PIH. I was worried that with such efficiency it would damage my sensitive skin, but instead I woke up with softer, less rough/smoother skin texture and the darker reddish pigmentation is less noticeable. My skin is also tighter and the pores are less noticeable. I’m impressed, this is a life changer for me if the results are consistent. With new products my skin will eventually get accustomed to them and it’ll stop working for some reason. I’ll post an update if that’s the case, but for the price I’m gonna try their other products too! I’ve always had hyperpigmentation but I didn’t know that’s what it is, I didn’t wanna whiten my skin for no reason. These products exist for dark SPOTS, which is what I struggled with my whole life due to this ignorance. I don’t know why it worked so well for me, for extra information I have combo/oily pale olive toned skin with red hyperpigmentation on the cheeks, and I get acne on my chin area mostly.

Does not irritate skin leave skin smooth!
I have no skin irritation from this product, which is perfect. It smooth out my pores. The quality seems to be great. It absorbs very quickly. It has no scent and for the price. I think it’s great value.

Works!
I’ve definitely noticed progress with my acne scar fading. It’s really stubborn, the shade is really dark, but after using it, I’ve definitely noticed it begin to fade over the span of weeks.

Moisturizing but no pigmentation effect
Been using this 2x daily for about two months and I don't see much change in my dark spots, but it's moisturizing and did not irritate my skin at all so I will continue until I finish the bottle. For context I have fair skin with freckles and do not have sensitive skin.

Works
This helped lighten up my dark spot. I'm almost out and went to order another bottle, unfortunately they're not selling it no more. Had to find another vendor.

Working
I have purchased several serums from Cos de baha. They are all decent quality for the low price in my opinion. This specific serum I bought to try to help with my sun damaged skin (admittedly I was not good to my skin when I was younger). It is a thicker serum with no scent, so it takes a few extra seconds to sink in, but it feels moisturizing at the same time. I have combination oily to normal skin, but there was no irritation. I've been using this for a few weeks now and I can tell a difference. My spots are fading and my skin has more of a glow now. It's taken a few weeks and I will continue to use it to see if I can get it looking a little better, but I would say it's doing what it said it would. I would recommend this to those that want to brighten and lighten up their skin.
