Very nice

I needed a new vitamin C as the one I currently use and love is very expensive and over £100! I saw this in the January sales for half price and thought I would try it. It is nice and has a consistency that’s similar to the Summer Fridays CC serum. It does smell of strawberry quality street. I haven’t seen a huge difference yet but it works well with my combination skin.

AMAZING!

An absolutely amazing serum! Fell in love with it from a sample and had to purchase the full size. The texture is luxurious, and the chocolate scent - such a pleasure! The most important aspect is, of course, the results - great stable Vitamin C that doesn't irritate my skin and actually works towards healthier skin. It has reduced my sun spots already after 2 weeks of use. Amazing! My absolute favourite 😍

Great for pigmented skin

This serum was perfect for my skin at the age of 45, now it is my favorite, and I have tried many serums with vitamin C, since I use it all the time. The serum perfectly evens out the tone, absorbs quickly, no stickiness for you for long minutes. In my opinion, she has one drawback - the smell, for me it turned out to be unpleasant somehow technically vanilla.

okay vitamin c serum

I use a vitamin C serum daily so I've tried lots of difference kinds. This one is perfectly fine, but doesn't have the extra "zing" which bumps it into "I LOVE using this" territory for me (Drunk Elephants and Paula's Choice vitamin c serums hit that spot for me). It's expensive, and also has a really odd smell which I didn't care for. While it idn't pill under SPF or makeup, this is one that I'll use but not not one I'll repurchase.

Gorgeous

This is exactly what I expect a serum to look like feel like and loved it…. No scent that I could notice, it did feel like a moisture veil- shimmers which I love and feels like serum I personally wouldn’t need moisturiser if applying make up. I would give it a go at this price.

Super!

Really enjoy using this serum. Initially got is as a tester and was impressed with the results so had to purchase the full size. It absorbs very quickly and smells really pleasant to me. My skin tone generally evened up and developed a natural glow. Overall, I find it the best vitamin C on the market.

Good vitamin c serum

I received a sample of this in a gwp but it was large enough for me to use for a while. It is s thick serum with a lovely orangey scent. You only need to use a tiny amount. Skin feels a bit tacky if you use too much. It plays well with other skincare and doesn’t pill which makes it great to use in the morning. It also gives you a lovely glow.

Good serum

I received this as a GWP. It is nice serum, the texture is lovely and, as others have stated, it has a really nice smell. I have used some other vitamin C products that I have preferred (Sunday Riley CEO products) but not another serum. If you are looking for a vitamin c serum in particular, this is a good option.
