It stings my skin and gave an uncomfortable feeling after applying it. I kept having breakouts so I guess my acne need something else.

I thought salicylic acid would solve my acne problem but this is clearly not for me. The only good is the price I guess.

No bad experience using this product. But it&#39;s not targeted for my acne problem hence I decided to change to another products. A bit expensive if I want to recommend to non-working people (broke student like me esp).

This is the best hydrating serum I&#39;ve ever used but unfortunately it is a bit expensive here in Malaysia as compared to Europe. I used it every night and it left my skin feel soft, hydrated and energised in the morning. It claims to be anti-aging but I couldn&#39;t appreciate it since I was only 23 yo when I used this serum.  Consistency wise it&#39;s quite concentrated hence one bottle of 30ml lasted for 3 months since I only used it at night.

It started to irritate and sting my skin after a while so I&#39;ve stopped using it. I really hate the smell and the powdery feel when I applied it. I&#39;m not sure if 10% is too concentrated or whether azelaic acid is simply not suitable on my skin.

I had tried this product for 3 or 4 tubes and at first it works on my skin without any irritation. It did fade some my acne scars but it takes time. It&#39;s quite cheap compared to other azelaic acid products out there. 50ml tube could last for 6 months since I only used it on my scars and at night.

No bad experience in particular except that it&#39;s too mild for my scars and acne prone skin.

Picky said this one is risky for me but I&#39;ve tried about 4 bottles of this on my acne scars. I personally love it because of the 2 ingredients combination. Alpha arbutin to fade out dark spots and HA to hydrate. The hydration part was okay for my skin and the anti-pigmentation part may require a little bit of work. Can&#39;t really tell whether it works well on my scars because my breakouts are endless. For some reasons, I like the tacky sticky feel after applying it. It&#39;s very concentrated but not too heavy on my face

I used this during the time I had no ideas at all about a good skincare routine. As far as I can recall, this toner really did what it says. It&#39;s very soothing and cooling after I washed my face. I only used this once so can&#39;t really tell the maximum benefit.
