Glo Therapeutics Ultra 15% Vitamin C Serum – Reviewed and Rejected

Is a Solution for:
Sagging Skin
Reviewed by Shyema September 15, 2010 8 Comments
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.

    Thank God for your review. I know that this is a few years old but I am so glad I found this. I started using this serum on recommendation of a friend and I used it for 2 days before I noticed how my skin had broken out in some sort of rash. I have never had bad breakouts or acne at all, at most a few pimples maybe once a month and at the time when I started using the serum my skin was really in a very good place, well moisturized, no breakouts or blemishes, smooth and with an even tone I had finally managed to get it to using soothing cleansers etc.
    I started to notice that my T-zone and cheeks had become bumpy and that I had a lot of white heads popping up, the skin is also very sensitive and seemingly flaky and oily at the same time. The only thing that has been different in my routine is the serum and I have never had this type of problem with my skin before. I have tried to put on the night cream I usually use and my face has just been covered with a film of oil in the morning.
    It has really affected me to see my skin go from completely healthy-looking to bumpy, red, tender and with white-heads everywhere. I am on the second day of not using the serum but my skin still has loads of white-heads and is very sensitive, I was really hoping that someone could offer some advice or just the reassurance that it will stabilize?

    I have this and love it.. I have had a totally different experience but my skin type is dry. I do find that it stings if I use too much and in the beginning because of the consistency I was a little heavy handed. I will say that I absolutely love it and after using Ole Henriksen's vitamin C serum for my morning routine and now this-- this is definetly the real deal and I see results.. Everyone's skin handles product differently.. Maybe Ole Henriksen's would be a little more gentle?

    Truth be told, Shy, it seems as if some reps from Glo themselves wrote comments on your blog post; they're all kinda mean!

    Anyway, THANK YOU for sharing YOUR experience with us. Though others may not agree or have had the same experience I do appreciate you sharing your experience. Keep on blogging! :)

    If you look up this product on the glo website, it clearly states that it is for all skin types EXCEPT acne prone skin.

    You should exchange the Ultra 15% for the regular 15% serum since you are in your your 20s. Then place 5 drops on the back of your hand and apply to your clean DRY face with your finger tips to avoid stinging from the ascorbic acid. Should it still sting you may want to go down to the 10%. Always get a sample to practice on at home before you shell out that kind of cash.
    Don't give up.
