Lovely and lasts ages!
I'm still getting through this having used it every day for months. I really like the texture, and how easy it is to use. 6 drops is recommend for face and neck, which is what I've been doing. It seems a little goes a long way. It sinks into your skin beautifully... I do think I've seen better results with the Summer Fridays CC me serum Vitamin C... but that is uber expensive and I get through that a lot faster which kinda breaks the budget. So for now, I'm happy with this Vitamin C from Medik8 but I think it is less effective than other products on the market. I would probably try other Vitamin C products to get the same kind of results as I've seen with Summer Fridays before repurchasing this one from Medik8.

The Best Vit C Serum!
I received this free in a goody bag but will definitely be repurchasing once it runs out! Which won't be for a while because you use just 6 (SIX!!) drops of this thin, oil like serum to massage into your face, neck, and decolletage. You'd think such a small amount wouldn't reach that far but it does. The serum itself smells gorgeous, like fresh bruised orange peel, and leaves perfectly velvety skin in its wake. Highly recommended for your morning vitamin C needs, you can't get much better!

Luxurious serum
I’ve been pleasantly surprised at how nourishing and luxurious this serum feels on the skin, at first use. My skin glows after using it and I’m looking forward to the ongoing vitamin C and E protection 😊.

Lovely vit c serum!
I’ve been using this over the last couple of weeks, after taking a break from summer Fridays vit c as my skin had become quiet sensitive it (even though I had used it for two years!). This serum is going to become a staple in my routine, it’s more of an oil texture so feels luxurious on the skin and I’ve started to see an improvement in skin texture with no irritation.

It seems to do wonders on my skin overnight, leaving it smoother and silkier the next day

The best vit c
I got this in a pack last year and it really was the most I’d seen an effect on my skin from a vitamin c serum. It cost more than my previous serum but worth the extra cost

Excellent
Beautiful light weight and no. Greasy Glides on your skin and gives a really nice glow. I had pigmentation on my skin and this has lightened it considerably. Definitely worth a purchase

So good!
Agree with my fellow reviewers here - great ingridients, non-sticky, slides like a dream and has a very subtle smell. I use it after lotion and before my Medik8 SPF50 moisturiser in the mornings during summer months. Will continue to use all year round! Such a great relief after using the Drunk Elephant Vitamin C serum (I was NOT impressed with that one!).
