Reviews
Excellent vitamin C serum
"I’ve really enjoyed using the Medik8 C-Tetra Advanced Gel Serum. The lightweight gel texture absorbs quickly without feeling sticky or greasy, making it perfect for my morning routine. It leaves my skin feeling hydrated, smooth, and refreshed, and over time I’ve noticed a healthier-looking glow and a more even complexion. It layers well under moisturizer and sunscreen and hasn’t irritated my sensitive skin. A high-quality vitamin C serum that I would happily repurchase."

C-Tetra® Advanced
"I’ve been using C-Tetra® Advanced for a while and overall I really like it. It feels lovely on the skin and my complexion looks brighter and healthier. I do still have some brown spots/hyperpigmentation that I haven’t noticed much improvement in, despite using it consistently. I was hoping it might do a little more for those, but overall I’m happy with it and enjoy using it."

A noticeable difference to my skin
"I love all of my Medik8 products and C-Tetra Advanced has become another favourite. Since adding it to my routine, I’ve noticed a real improvement in my skin – it looks brighter, smoother and generally much healthier. It feels lovely to use and works beautifully alongside my other Medik8 products. I’m really pleased with the results and will definitely continue using it. ⭐️⭐️⭐️⭐️⭐️"

Fantastic Vitamin C Serum
"I’m extremely happy with this Vitamin C serum. It fits perfectly into my skincare routine and layers beautifully with my other Medik8 products without causing any irritation or pilling. My skin looks brighter, healthier and feels smoother since I started using it. The texture is lovely, absorbs quickly and leaves my skin feeling comfortable without any greasy residue. I look forward to using it every morning and will definitely keep repurchasing. Highly recommended!"

A Daily Essential
"I use this every morning after my Peptides Advaced MP and it's now an essential part of my morning skincare routine. The texture is lightweight, silky and it absorbs beautifully. Since using it consistently, my skin looks brighter and smoother. I would definatley recommend C-Tetra Advanced to anyone looking to add a high-quality effective vitamin C product to their skincare routine."

C-Tetra™ Advanced Gel-Serum - C-Tetra™ Advanced Gel-Serum (P11820)
"I’ve been using the C-Tetra™ Advanced Gel-Serum for a month now, and I really enjoy its lightweight texture and pleasant scent. It absorbs beautifully and feels very comfortable on the skin without leaving any sticky residue. However, I haven't noticed any visible changes in my skin tone or texture yet. I specifically hoped it would help fade a few stubborn hyperpigmentation spots, but they remain unchanged so far. I understand brightening takes time, so I will continue using it, but I’m still waiting to see noticeable results."

Best Vit C serum ever
"Absolutely love this, it gives my skin a lovely glow, it’s helped reduce some of the brown spots I had, my skin looks amazing, it’s one product I can’t do without, and it smells lovely too, skin feels so soft and it sinks in without any greasy texture or tacky feeling, can’t recommend this enough"

The Best Vitamin C — Period
"I’m on my third bottle of this Vitamin C serum, and I honestly can’t imagine being without it now. It has a beautiful texture, sinks into the skin easily, and has a really nice, subtle scent. Most importantly, it works — my skin looks brighter, smoother, and healthier when I use it consistently. I’ve tried other Vitamin C serums, but nothing else has compared. This is hands-down the best I’ve used, and I’ll keep repurchasing it! It’s great that I can purchase in Canada now. I used to have to jump through a few hoops to purchase it."

Really good
"I love the texture and scent of this vitamin C serum! It feels perfect for my skin type and absorbs beautifully. The only reason I’m giving it 4 stars is that, after two months of consistent use, I haven’t noticed a dramatic or spectacular improvement yet. I’m still enjoying the product and will continue using it to see if the results improve over time."

I’ve been testing the Medik8
"I’ve been testing the Medik8 C-Tetra Advanced, and it’s a powerhouse for dull or uneven skin. The gel-serum texture is highly practical, absorbing smoothly without the typical oily heaviness or sticky residue of high-strength Vitamin C formulas. Packed with a 20% stable C-derivative and phyto exosomes, it works beautifully to visibly fade dark spots, even out skin tone, and boost radiance."
