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

I usually use Timeless 20% but have had issues with it oxidising and it's expensive. This product was a good alternative and so far has not oxidised after a few weeks of use. I've kept it refrigerated. My skin looks bright and the formula does not irritate my skin. I'll definitely order again.

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

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.

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.

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.

There is no doubt this benefits the skin in terms of brightness. It has a consistency like water. Very mild 'hot dog water' smell as per all unscented Vitamin Cs, but not a strong as some and very tolerable. The reason for my 3 stars is it makes my skin feel sticky despite going on smoothly.

Noticed a difference in a couple weeks. I do as it tells me and decant it into a small 5ml container and keep the rest of the bottle in the fridge. Lasts ages and genuinely works. So impressed for the price point!

The best before date for this was four days after I received it. There’s no way anyone could use a whole bottle in four days!
