Hydration
My usual moisturising creams were cutting it this winter dispute using water based serum & Moisturising cream & primer my skin was still dry/but using this oil based serum first has saved my skin & makes my make up sit so much better / second bottle this season!

Doesn’t absorb quickly
I love medik 8 however I find this does not absorb on the skin easily, it’s a bit greasy! Maybe not great for my oily/dry skin

Caused dryness
Wanted to add this into my skin care routine as I needed a little more hydration and brightness to my dull menopausal skin, I used for 2 days! the texture and ease of application was perfect and loved how my skin felt but the 3rd morning I woke up to find my skin was extremely dry and reactive so stopped using it, now the 4th day has passed and I have little spots caused from sensitivity, going to take a while for my skin to get back to normal and all because I read the reviews saying how hydrated and great there skin looked, my skin feels like it’s been burnt, very disappointed as it was an expensive purchase and I do understand that there is the odd person that will react to a product and it happen to be me.

Great but not for me!
This is a lovely product, but I have very oily skin & it was just too much oil for my skin in the daytime. I am however using it up on my neck, décolletage & back of hands which works well!

Excellent
This is a great vitamin C. So many of the other formulas I have tried are grainy and feel scratchy on the skin. This is a lightweight, almost dry oil feeling. Excellent - especially if you have drier skin.

I use this in the morning under my liquid peptides and medik8 vit c cream. Have noticed my skin tone is brighter and more even. I use retinal at night in my routine. Love medik8 products. Will always use them. Definitely recommend.
