this to me is a fairly new discovery. not only the product but also the brand as a whole. i have always sort of been struglling with the same stubborn skin issues like dullness and post inflamatory hyper pigmentation. I have been hearing about this product in the skincare sphere lately and decided to give it a go. combined with niacinamide from Tiam and propolis serum from beauty of joseon this helped me TRANSOFRM my skin. i notice less dull complexion and faded pigmentation. i will keep using it for the upcoming months and see where this will lead. for now loving it. yesstyle is my one stop shop for all things korean beauty and skincare. for now I am also considering japanese beauty on yesstyle. fingers crossed to come across more gems like this one

Why is this acid so underrated?! If you have acne and have tried everything, get it. I cannot say enough good things about this serum. For the price the quality of this is REALLY good. Clean, simple formula. I only know about this acid after youtube reviews and how all of them are raving about this acid. Some say they prefer using this over retinols. So far this helped to improve my scarring and eliminate breakouts, but on the other hand it didn't made my skin as irritated when using retinols. This is a must have for people suffering from acne but of course you should build up the strength slowly in case it's too strong for you. Please like if this review helped!

I have sensitive skin that is prone to breakouts. I will get closed comedones immediately if my skin does not like a product. I cannot use "The Ordinary" products, because something about their formulation always gives me acne. This product is a great alternative and I have not experienced any breakouts. I can use this product daily. I did not experience burning or stinging. I also have combination skin that gets oily but can get dry and flakes in places, and this product did not worsen any dry patches. It is moisturizing without feeling oily.

I love the consistency, it reminds me of BOJ Glow Serum, it feels at little sticky but leaves my skin really hidrated, must be the Hyaluronic Acid in it. It's a low concentration but great before you decide if you want to go for a higher % in the future.I have been using this for almost a month, started slowly the first 15 days, just once daily, now building up to twice including at night.I have heard that one has to be patient to see Azelaic Acid produce results, so I'm expecting improvements in pimple marks fading and redness around my nose being reduced.But for now, my skin feels so much softer and it looks overall healthier.
Oh I love Cos de Baha products! I’ve been using this in the morning after cleansing and toning for the past few months and the effect on my skin has been amazing! I am acne-prone and I usually suffer from redness. I’ve tried lots of products, different serums and supplements but this is the only serum that helped me. The serum is moisturizing, and a little goes a long way. This comes in a 30 ml size and very gentle on skin. Highly recommend this one!
Well, I bought it as its best for reducing dark spots and even out skin tone. This was the product I was most excited about! However, I find that it gives me tiny bumps each time I use it overnight. I wake up with tiny bumps which I then use cos de baha aloe serum to calm my face. The tiny bumps takes a few days to go away and I’ll try again, but the same thing happens. I now switched it to use in the morning and wash my face a few hours later. It doesn’t cause the little bumps but I’m unsure about what it does for me. I prefer cos de baha glycolic acid.
It's a very nice and affordable serum. It lasts me about 2.5 months if I use it almost everyday. I like the way it spreads, even a small amount of serum can be spread over a big area. I have combination, acne prone skin with a very oily forehead and my skin is often dehydrated. I find this serum to be helpful in reducing inflammation and to some extent fading hyperpigmentation. It also doesn't cause any irritation, clogged pores or exacerbate dryness. (I use a fairly rich moisturizer though, so it helps with reducing any side effects). I feel like this serum also prevents new breakouts.
for the first time I encounter acids, I took it to eliminate traces of post-acne and for an even skin tone. I’m using it for the third day, it’s too early to say anything, but the fact that the serum did not cause irritation is already a plus. I will track the result. the texture is like an aloe gel, there is practically no smell, half a pipette is enough for the whole face.the bottle is made of plastic, I would like it to be made of glass, the weight itself is transparent inside, of medium density it is distributed over the face quite easily, without a sticky residue.
i like the oily texture of the serum, it applies smoothly and doesn't feel too tacky/sticky on my skin, and it doesn't pill. this was my first time trying azelaic acid and i started breaking out really badly around 2 weeks after using this and it lasted for a really long time. not sure if it was purging or anything, but it did bring all the acne lying dormant underneath my skin up to the surface. my skin does feel a bit smoother in other areas but it didn't make my break out go away and help reduce my acne in my t-zone, which was quite disappointing because i heard many good things about this product. would like to try more azelaic acid products to see if its just the ingredient that im reacting badly to. not quite sure if i would repurchase.
