Mizon - PickyMide review for Hyaluronic Acid 100

I used it at the beginning everyday in my morning and night routine and I got some pimples. At first I was not sure if it was because of that serum and I tried to avoid it to see if it really is the serum. And yes it was it. Now I use this just before a full face of make up and every 3 to 4 days on my night routine. and it works like this for me. But I won't repurchase it. not because it is bad but because I think there are better alternatives.
