The first time I came across Glo Therapeutics was through my facialist, who recommended their brightening serum for some acne scarring. I shelled out $48 and used it religiously. I wasn’t a fan of the stickiness and although it did help to lighten the scars a bit, I felt like it was quite a long process and didn’t completely go away. She highly recommended the line though, so when I got sample of the Ultra 15% Vitamin C Serum ($85) from their new Moisturize & Restore line, I decided to give it another go.

Before even using it, I looked up reviews online. Since it’s so new, there weren’t many, but the ones I did find mentioned that it was non-stinging and after repeated use, they noticed a nice “glow” to their skin. This serum is also filled with collagen stimulating properties: arginine is an antioxidant that’s supposed to help build collagen; zinc sulfate removes old stiffened collagen so new ones can be made; L-tyrosine (acetyl tyrosine) is an amino acid that increases collagen production by encouraging fibroblast activity; and Longevicell (hydrolyzed myrtus communis leaf extract) is another antioxidant and cell regenerator said to inhibit the glycation of collagen. Truth be told, I was more drawn to what I hoped would be the brightening effects of its lemon peel extract and, of course, ascorbic acid (or vitamin C) which also improves skin elasticity, since I do have some issues with the clarity of my mid-20s skin.

The first thing I noticed in my initial trial was its consistency, which is like water. It comes in a dropper bottle, so I tried to pour a little on my palms but it ended up spilling messily down my arms. The next time, I tried applying it directly on my face, but again, it quickly dripped down my neck. Finally, I realized the best way to apply this was to just add a little to my palms, rub, then wipe over my face.

Now, I’m not sure what those people are talking about when they say it doesn’t sting, because every single time I applied it, there definitely was a light stinging that would last a few seconds. I kept at it though, using it once in the morning and once before bed. After a few days, I noticed I began breaking out. It was first one or two, then three or four zits in different areas of my face. I began scarring worse than before I started using the serum! This was definitely not what I thought I signed up for. I tried to wait it out, but now, after three weeks of use I'm finally giving up. Looking at the ingredients, I’m not sure what caused my skin to react the way it did. Maybe it was just not suited for my skin type which is a bit combination.

The other thing is the price -- $85 for a 1 oz serum? I have to admit, I am sometimes swayed to think the more you pay, the more you get. But in this case, I can say that isn’t necessarily true.
