Dr Song - Vitamin C Serum

I've added this to morning routine for 2 months and the difference after 3 weeks was amazing, now it boggles my mind. I keep this in my fridge to keep it fresh. I use all their products religiously. I've bought 2 bottles since just for backup

The texture and consistency is pretty much just like the HA serum, but ingredients wise they aren’t the same (but this one has HA in it, like I said, everything has HA). This didnt irritate my skin

so far so good! hopefully i see a change
