Sadly did not see the results I was hoping for. [SEP] I purchased this on the first week of January. It’s been a few weeks and I’m almost done with the Glow powder, but sadly I didn’t see the results I wanted to see or thought I would get with these products. The collagen liquid is in a big bottle and will last about 2 months or more but the powder is almost out and it hasn’t even been a month. I have been using the proper measurements but sadly did not see the results I was searching for.
