Great Serum - 18-06-2018 by

The perfect serum for anyone looking to brighten their skin tone. Very gentle for such a strong vitamin c product, and I have quite sensitive skin. Bit of a strange smell and texture when you first apply, but dries within 3 minutes and smooth for moisturiser application. I also find it's used best without a hyaluronic serum underneath. Would definitely continue to purchase!

Great Vit C serum - 25-05-2018 by

This is the third Vitamin C serum I've tried from Deciem, and - like The Ordinary's Ascorbyl Glucoside Solution 12% - I haven't had any problems at all. This is more powerful (I think?) but hasn't caused me any redness or breakouts, unlike The Ordinary's Vitamin C Suspension 23% + HA Spheres 2% - which I think was mainly because of the oily base. I find that Hylamide's Booster series all absorb really easily and don't cause my skin any issues. This is a great serum.

That 'brightening' effect. - 30-04-2018 by

This has been my first experience with a dedicated vitamin C 'booster' and I'm very glad I tried it. I do feel it helps to 'brighten' my skin, its hard to explain though. I have dry, somewhat sensitive skin and choose to use this about twice a week, its easy to apply and seems to sink into my skin. Will continue to use.

Favourite Vitamin C - 06-02-2018 by

Having tried quite a few vitamin C serums, I've always loved the results I see but have struggled to find one I liked the texture of until I tried this one. This is the only vitamin C that I find applies smoothly to my skin and doesn't ball up or flake off when I rub it in which is a huge winner in my eyes. I see results after using this for just a few days. I couldn't agree more with the claims that this product makes. I definitely see a huge difference in the overall appearance and radiance of my skin and will continue using this as part of my daily routine.

Didn't work for me - 02-10-2017 by

I tried this hoping it would fade my sunspots and improve the appearance of my skin but after months of use I didn't notice any difference.
The packaging is cute, and the dropper is easy to use.
I took about three drops and it spread out well. It did feel oily, so I had to wait at least an hour before applying moisturiser. And I did always have to apply moisturiser as this is not hydrating enough on it's own.
After a month I noticed some bumps on my jawline but hoped it was from something else and I continued to use this. However, after continued use I couldn't deny that this product was the culprit and I had to stop using it.
No improvement on the skin and cause bumps, disappointed.

Found this very irritating - my delicate skin can't tolerate it - 27-07-2017 by

I have been trying to get used to this for many months. Took me a while to realise it was this and not my retinol causing the irritation and flaking. After more than a month since last use, my skin was calm and happy again. I then tried it again. This time I was more careful with the quantity and only applying to face. I then followed it with hyaluronic acid and moisturiser over face and throat. Next day face and neck irritated. Welts on neck and several days of flaking on face including lips that felt sunburned. Apparently just the trace amount on my hands was enough to bother my neck skin.

So as a person with delicate, pale skin prone to dryness I am coming to believe that there is just no way I can use this product. I've used Aspect's Vitamin C with no difficulty and actually found it pleasant. If you have stronger skin than mine maybe this will be ok for you, it certainly is potent!

Great vitamin c hit! - 13-01-2017 by

This is a great C serum - it reminds me of another brand I've previously used that is 3 times more expensive but seems to provide the same result for me.
Helps to brighten skin, I like the consistency (blends fine under makeup & doesnt 'ball up' on skin like some do), a more affordable version as some serums cost the earth! I have dry sensitive skin and my skin really responds to this - no negative reactions! Look forward to trying the result of hylamide serum range.

Absolutely Essential Product to add to your Skincare regime - 06-12-2016 by

After trying Kate Somerville's Mega-C Dual Radiance Serum with disappointing results, I tried Hylamide C25 Stabilised Vitamin C Booster. You literally cannot go wrong with this product - there is a noticeable difference within the first few times of use. Good for all skin types, but as I have sensitive skin it is refreshing to be able to use a highly concentrated vitamin C product without causing irritation. Honestly cannot function without this and cannot recommend this enough. Do yourself a favour and get this in your life.
