I bought it for my Son.Very good results for just a few times of use

Lightweight hydrating serum Absorbs easily into the skin Reduced frequency of my acne Contains niacinamide for antioxidant effect Helps to control hyperpigmentation and is anti inflammatory

Very good product, improved skin texture

I love this Serum, it makes my face brighter and soft Highly recommended!

Love this product the best for my acne prone skin

Not sure one bottle is enough to see results I haven't.

Great price, not sticky, and had a great formula of supporting ingredients. I’m done trying different Azalaeic acid serums, this is the one!

I use both the toner and serum daily and after 3 months I have seen so much improvement to my acne and redness. This combination is the only non-prescription treatment that has ever reduced my acne. I love these products and will buy them regularly! 

I love this product, my hyper pigmentation is slowly fading! I’m so excited! My ores have actually been minimized!

Love it and it’s really calming for acne ❤️

I really really really love these product so so much!!! Absolutely amazing! Obsessed!

Azelaic acid has significant soothing effects on the skin and helps improve skin texture. Redness evens out skin tone and reduces pigmentation and blemishes

Absorbs pretty well. Sets ro a natural

Hasta ahora tood bien, tengo que seguir dandole tiempo a ver que tal me va

Estoy demasiado feliz con estos productos deja mi piel bella fresca y suave me encanto

I saw little change to my skin but i think i used it wrong so maybe that’s why.?

this works so good for soothing redness. I like to pair it with the matching toner. I notice a difference in my skin for the better when Im using this so I bought a back up bottle too so I don't run out

I use it while pregnant because I cannot use retinoid. It helped with acne and acne scars

works like magic for PIE

This serum has a silky watery texture that absorbs instantly into the skin. It is hydrating and non greasy. It leaves my skin smooth and free from breakouts and also reduces redness and inflammation. I absolutely love the formulation and ingredients in this serum, perfect for my oily acne prone skin

To find a 10% percent Azealic Acid formula that is basically water-like and plays well under other products is a true achievement. I haven't seen results yet but am anticipating them as my skin is breaking out and red from retinol

This is so good and it clears up your dark spots!

Nice smooth texture, thin consistency. if you're hesitant because other products with snail can be stringy, no worries, this one doesn't have that issue. This is going to replace the cos de baha in my routine--it's not sticky or tacky, much easier to add in any routine!

شريته لان نوع بشرتي مختلطه مع وجود ورديه بسيطه على الخدين من تركيبته راح ادخله بالروتين مرتين الي ثلاث بالاسبوع للتحكم بالاحمرار مازال تحت التجربه.

My favorite serum so light weight and work good

This product is work as it advertise. Good

Azelaic acid is a *great* ingredient for acne, redness, texture, anti-aging, and more, but I haven’t seen it much in K-beauty (this seems to be the only brand on Style Korean that has it?), and it’s hard to find in forms that aren’t kinda thick and pasty creams that don’t really play well with other skin care or makeup products. But this serum showed me that it doesn’t have to be that way! It’s definitely a serum that spreads easily on the face, even though it is a bit sticky. I’m pretty sure the stickiness is due to the addition of snail mucin, which is full of skin-boosting peptides. It also has niacinamide and panthenol to contribute to skin health and softness. (The 10% Azelaic acid is the star of the show, though — for people worried about the other ingredients dominating, it only has 2% niacinamide, 1% panthenol, and ~1% snail mucin: enough to have effect, but still quite gentle.) I’m definitely going to buy this again, and continue looking into this brand!
