Love this Vit C serum!
This is my second bottle now! I stopped using it after my first bottle finished as I didn’t realise how much of an impact it was having. My skin was a lot brighter when I used this everyday and over time I noticed a difference in my complexion looking more even. The smell is uplifting and I don’t find it too overpowering. The same applies for the texture, it goes on smoothly and feels light on the skin without feeling like it does nothing. I now regard this as a vital part of my skin routine and wouldn’t be without it.

Love this Vit C serum!
This is my second bottle now! I stopped using it after my first bottle finished as I didn’t realise how much of an impact it was having. My skin was a lot brighter and even when I used this everyday. Love using it before I wear a lighter foundation and it always helps keep my skin healthy!

Glowy skin
Smells divine. Leaves skin feeling hydrated and with a lovely glow. A lovely step in my skin care routine, just before I apply my moisturiser.

Sadly silicone based
Sadly silicone based serum, meaning that it does nothing but creates illusion of skin getting better for a few days while it plugs pores, wrinkles and fakes better skin...

Nice
Nice serum, makes my skin radiant, tool one star off because it’s too oily as for serum

A great vitamin C option
I really wanted a no fuss vitamin C product that I could incorporate into my morning skincare routine and this product is it. It feels very liquidy when you drop it onto your hand but then when applied to the face it feels quite satin like. I leave it to absorb before applying my other products and it feels great. Overall my skin has never looked better and this product is part of it. I've now went through 2 bottles and repurchased my third, I can't see anything replacing this anytime soon.

The best
I have repurchased this serum already and I think I won’t try other vitamin c products. This is very good for my dry skin. Has a pleasant scent too.
