Geek & Gorgeous 101 C-Glow - 15% Vitamin C Serum, super-light + Ferulic acid & vitamin E, gives environmental protection, boost collagen & evens skin tone - all skin types, 30ml

Very good quality pure vitamin C, not too strong but it does sting a bit. It arrived completely clear and in date, I kept it in the fridge and it stayed completely fresh until I used it up. The price is also very reasonable, so it is great for a pure fresh vitamin C that is not too irritating. I didn't use it long enough to notice any brightening effects as such, but compared to other vitamin C serums I have used, this was less irritating and easy to incorporate into my routine.

Good if you're new to using Vitamin C. Doesn't irritate the skin. Promotes a beautiful glowing complexion.

This is a great dupe of the v expensive medical grade one you can get for £170, same ingredients and same effectiveness. Be careful buying this from Amazon though, took a star off as the bottle I ordered only had a month left on the expiry… it has a very short shelf life in the first place, so maybe better to order directly from their website to be honest to get the freshest products as this particular vitamin C is not the most stable, but it does a good job of evening skin tone out and is good skin protection as well.

As I had used vitamin c serums in the past that broke me out, I was a little bit hesitant to buy this vitamin c as I didn't want to waste £12 on a product I wouldn't use. Fortunately, my skin has been loving this serum so far. I've not noticed any irritation but my skin feels a little warm after applying it.It's a very watery serum that absorbs quickly, leaving my skin glowing. 15% vitamin c with vitamin e & ferulic acid is the gold standard, so for £12 this serum is incredible. I would much rather pay £12 than an eye-watering £165.It smells a little bit like 'hotdog water' like vitamin c serums I've used in the past but much less than the other ones. I decanted 10ml into a small dropper bottle I keep in the bathroom (Geek&Gorgeous recommends this) and the rest is kept in the fridge to slow down the degradation of the vitamin c so it will last longer (the serum is clear so you know it's fresh and will last a while before needing to worry).I've not been using it for long so I can't comment on the long-term benefits but I expect to see a reduction in PIH, softer and bouncier skin and protection against environmental stressors that could worsen acne. This review will be updated in time.

The glow from this is spectacular! It's like nothing I've ever tried before.The first couple of times using, my skin was a little sensitive, but this is expected with Vitamin C products. Within a few days, my skin was glowing, fresh and feels silky smooth.The consistency is thin and a little goes a long way. I don't find it to be sticky at all, and it will forever be a staple in my morning routine.

It’s gentle and non irritating, doesn’t have a strong odour. This was my second order of Geek & Gorgeous C-Glow. I’ve tried Timeless before and I prefer G&G. The only downside, for me anyways, is it’s inconvenient for me to get and options are limited: I order from Amazon UK but it’s about 3-4 weeks shipping to Canada (and a bit pricey) and G&G itself uses DHL which has exorbitant fees. Also, my last order I ordered two C-Glow’s and Amazon sent one C-Glow and one Stress Less (attached photo). I keep my vitamin C serum in the fridge so unfortunately I only noticed this months later when after finishing the first bottle I went to grab the second one from the fridge and uh-oh, what is this? Both packages are designed the same. Amazon missed it, I missed it initially. I haven’t ordered this product from anywhere else so it’s with certainty where the mix up occurred. Unfortunately, this means I’m all out now with no means of getting it again quickly. One less star for Amazon messing up the order, one less star for the company packaging.

Having researched a ton of Vitamin C serums I chose this one as reviews described it as getting great results at an incredible price point. So far it doesn’t disappoint. It’s a really light watery serum that sinks in easily and is non-greasy, very easy to add into my skincare regime before moisturising. I did get a slight tingling but nothing uncomfortable.Some reviews complained about the short use by date; they clearly aren’t aware of how unstable l-ascorbic acid is and how quickly it can oxidise. Geek and Gorgeous make this product fresh each week and advise to keep the bottle in the fridge to maximise the product life, and also recommend decanting a small amount into a 10ml dropper bottle - which is what I’ve done - which can be kept in the bathroom for convenience and won’t go off before it’s used.

Literally arrived 100% white and clear which means minimal oxidation and smells very fresh (not like hotdog water from other brands). The difference is night and day with a brand that costs 5X more. This is an extremely potent vitamin C while being very gentle on the skin. My skin brightened in a gradual and noticeable manner. I literally did not see any brightening with two previous brands I used (one was Sodium Ascorbate-based and other was L-asborbic acid). If you are planning on using this, make sure to get B-Bomb as well, it helps your skin adjust to the C serum and also has separate benefits. So happy that G&G exists and have amazing logistics at an amazing price!! This is godsend!will post pic soon
