Won't repurchase

Not sure that this really did anything for me. I've since moved on to another brand and didn't finish this bottle.  A nice product, but didn't feel that it was really working for me sadly.

What is this sorcery?

5 stars out of a maximum of 5

The texture, the consistency, the smell, the finish...everything is just right. I've managed to balance my hormonal skin so it was time to bring back in a Vit C and boy am i glad it was t his one. Super lightweight, feels like an oil but absorbs like a serum. I've been using for around a month i've noticed a difference is he overall tone/balance of my skin. I have some gnarly post blemish marks on my cheeks and i'm definitely seeing a slight fade/improvement. I don't have particularly sensitive skin (combo queen) but appreciate when products don't tingle/cause any sensation yet just work. A little goes a long way and i can't wait to see the results as i continue to use.

My Favourite So Far...

5 stars out of a maximum of 5

I love the oil-like texture of this serum, it's lightweight and can be patted in easily after toner. A little goes a long way (the instructions recommend 6 drops) and it doesn't take long to absorb into the skin. My main pet-peeve with vitamin C is that some serums can leave a brown/ orangey stain on skin and clothing. I've found this constantly when using the Inkey List and Drunk Elephant Vitamin C serums, so I thought it was normal. Medik8's Vitamin C however does no such thing. There is no colour to it, which suggests to me that it's more fresh (tends to go orangey as it ages) and doesn't leave the collars on my clothing & bra straps with a grubby stain. I've been using for around a month now and am not even 1/4 of the way through the 30ml bottle. Looking forward to repurchasing!

Love this!

I love the smell and it’s make a difference to my complexion. I’m not usually a fan of oils but this isn’t too heavy and soaks in really quickly. I will definitely buy again - my skin is glowing!

Best vitamin C serum

5 stars out of a maximum of 5

My skin is generally too sensitive for vitamin c, but this product didn’t sensitize or dry my skin out. I can't believe how much I noticed a difference in my skin in just a few days. I have noticed that my skin is brighter, glowing and clear. I cannot recommend this enough. The smell is amazing!
