Great skin brightener
This is the 3rd time of purchasing this product and I hadn't used Vitamin C for quite some years. Just a few drops every morning, allow to sink in before applying Moisturiser, and you're good to go for the day. It smells slightly citrusy which is also nice. Recommended by a professional and I haven't looked back. I even receive 'glowy' comments on my skin and I'm over 60.

Lovely Serum
I love that after using this serum my skin immediately has a healthy glow, and feels / looks bright and refreshed.It has an almost velvety feel when applying but absorbs perfectly.I have sensitive skin, and did experience a bit of redness and mild stinging with the first few applications of this product, but now my skin is used to it, I find it soothing to apply.

Glides on easy
It's a brilliant serum and hydrates/plumps skin. Works well layering with other skincare product. I have combo skin and it's great. Only product I think is better is YTTP one but this is cheaper!

I received a small bottle of this in the advent calendar and had to purchase again as soon as I ran out - this has been amazing for my skin in tackling London air. It leaves my skin glowy and hydrated and has become a must have item for me

Serious brand that gives results
I was curious to try out the Medik8 vitamin C serum. I know they have different types of formulations (e.g. with additional ferulic) but I went for the simpler one. I haven't used it long, but I apply and massage it into my skin every morning and I'm beginning to see a clearer and healthier complexion. It is called a serum but the texture is more like an oil, which could bother some people. However, I haven't had a single breakout since using it and my pores don't feel clogged at all. The oily texture means that a few drops do go a long way. Happy with this product from a fabulous brand.
