DESCRIPTION

A proven low-irritation formula, 96% of sensitive skins found C-Tetra to be gentle on their skin.*

KEY BENEFITS

Daily Glow

The silky jojoba oil-infused serum works to effortlessly give skin a boost of radiance, promoting a visible healthy-looking glow in as little as 7 days.*

Antioxidant Power

Vitamin C and E provide daily protection from harmful free radicals generated by sun exposure, which can cause visible signs of premature ageing.

Gentle yet Effective

Tetrahexyldecyl ascorbate is a stabilised, gentle form of vitamin C which makes it perfect for those new to vitamin C, or sensitive skins that don’t want to compromise on results.

Looking for more power? Check out C-Tetra Luxe, with double the concentration of vitamin C as C-Tetra and additional brightening and nourishing ingredients for supercharged results.

HOW IT WORKS

Your skin contains natural antioxidants that work to defend against free radicals from the environment. When these environmental free radicals outweigh your skin’s antioxidants, the skin can no longer protect itself. Free radicals latch onto the defenceless skin cells, causing irreparable damage, which ultimately leads to signs of premature skin ageing.

C-Tetra works to protect the skin from free radical damage, featuring vitamin C to boost the natural antioxidant defence levels in the skin. Vitamin C is a key pillar of our CSA Philosophy, due to being one of the most powerful vitamins for preventing the visible signs of premature skin ageing. Vitamin C helps to brighten the appearance of dark spots and uneven skin tone. The result? Visibly radiant, more youthful-looking skin. C-Tetra contains tetrahexyldecyl ascorbate, a form of vitamin C which is a stabilised modification of ascorbic acid (the purest form of vitamin C) that is gentle on the skin yet proven to deliver visible results.

Vitamin C and vitamin E work together synergistically as 'network antioxidants', boosting the serum’s overall antioxidant effect to keep skin protected throughout the day.

C-Tetra is based on jojoba seed oil, for lightweight nourishment and an instant glowing appearance. The natural emollient oil slips effortlessly into the skin barrier, delivering the vitamin C benefits with ease.

Perfect Pair

When combined, vitamin C and sun protection give skin the ultimate protection against the sun and environment throughout the day, to minimise visible signs of premature ageing.

THE SCIENCE BEHIND

“It is exceptionally difficult to formulate a long-lasting vitamin C serum that will keep its power over time. It is notoriously unstable, sensitive to oxidation and can often turn yellow in colour, which indicates that it has gone off. Medik8’s C-Tetra range utilises an extremely stable form of vitamin C, called tetrahexyldecyl ascorbate. This molecule is altered to make it less reactive to oxidation, meaning that even 6 months down the line you can be sure your vitamin C is still as potent as when you first opened it.”

Daniel Isaacs, Medik8 Director of Research

HOW TO USE

After cleansing in the morning, massage 4 drops of C-Tetra Luxe across the face, neck and décolletage.

Leave to absorb before applying sunscreen. We recommend Advanced Day Ultimate Protect.

Missing answers to even number questions
Format: Hardcover
Great info but there are no answers for the even number questions. Only for the odd numbers. I would like to all answers to questions.

The Only Resource You'll Need to Pass the RHIA
Format: Hardcover
What did I like? This textbook is fully comprehensive of all that you'll need in order to take and pass the RHIA examination. I lost my credentials when I didn't renew my professional dues and needed to take it again after 26 years. Granted I have experience in the field, but this book covered it all. What did I use this for? I used this text to prepare for my RHIA exam administered by AHIMA.

Exactly what my sink needed!!
Color: Black, Color: Black
Okay, this thing turned out to be way more useful than I expected. It’s big enough to actually hold everything — sponge, scrub brush, even the soap dispenser — without looking cluttered or crammed together. Plus everything dries faster, so my sink area finally doesn’t look like a wet chaotic mess all the time. 😅 The quality is really solid too. Feels sturdy, doesn’t rust, and was super easy to install. It stays put and keeps water from collecting around the sink, which honestly makes cleanup so much easier. Such a simple little product, but it really does make the kitchen look cleaner and more organized. Definitely recommend.
