Unfortunately not for me
I use Differin - Vit A - and using this in the morning and Differin in the evening for the last two and a bit weeks completely wrecked my skin leaving it sore, dry and breaking out in spots. Even now a week on from not using the Vit C it's still a mess. I am very precious about my skin as I have had a lot of acne issues and now I am having to try and sort out the mess. I love your other products but this isn't good for my skin.

Favourite skincare staple
I've been using this for a year now and see a significant improvement particularly at this time of the year when I'm prone to rosacea. My skin is calmer and it feels like a luxurious treat every day

The best Vitamin C
I use Medik8 C-Tetra every morning, and it gives my skin such a fresh, healthy glow for the day. It’s a great opportunity to protect my skin from dullness and pollution before applying SPF. I also love the lightweight form - it absorbs quickly without any stickiness or irritation. Perfect for sensitive skin!

The first vitamin c I have not reacted to.
So happy with this product as I usually cannot tolerate vitamin c. Used slowly at the start and increased gradually with no reaction whatsoever. Highly recommend

Fantastic product
I purchased the travel size of C-Tetra as it was my first time using Vitamin C. I started slowly, applying twice a week, building up to every other day with no issue. The main things I noticed straightaway was how good my skin felt after application and the gentle citrus fragrance is wonderful. It's not greasy in any way, and is absorbed quickly into the skin. I'll start using it daily soon as part of my morning routine; I use Crystal Retinal 3 in the evenings. It's a bit too soon to show any drastic results, but at 54 my skin feels smoother and is the best it has felt for a long time.

Wonderful
Love this soothing C Tetra serum. It’s great in the morning and at night under my moisturiser. It’s a great base for make up too. It’s soothing and the perfect remedy for any dryness.

C - Tetra
Vitamin C Serum – I’ve been using this daily as my skin was looking quite dull. After just 4 weeks, I can see a noticeable difference—my skin looks brighter and more even, and my friends have even commented! Highly recommend.
