DESCRIPTION

A stabilised, low-irritation form of vitamin C, tetrahexyldecyl ascorbate, is delivered to the skin in a beautifully silky oil texture which can be easily incorporated into any routine. Squalane and vitamin F help to feed the skin’s barrier with moisture for an all-round, visibly healthy-looking glow.

Restores Visible Radiance: Vitamin C is joined by fermented red ginseng and maracuja oil for an all round unbeatable glow and healthy-looking, dewy skin.

Total Nourishment: The velvety serum also features squalane and vitamin F to deeply moisturise the skin. The silky formula is clinically proven to help strengthen the natural skin barrier, which ideal for dry and dehydrated skin types.

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 premature skin ageing.

C-Tetra Luxe offers optimum skin protection from free radical damage, featuring elevated levels of 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 helping to prevent the signs of premature skin ageing. Vitamin C also helps to improve the appearance of fine lines and wrinkles, and can help to brighten the appearance of dark spots and uneven skin tone. The result? Visibly radiant, more youthful-looking skin. C-Tetra contains an enhanced level of 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. C-Tetra Luxe has double the level of tetrahexyldecyl ascorbate found in the original C-Tetra serum, for improved visible results.

Infused with Amazonian maracuja oil, C-Tetra Luxe is powered by the exotic antioxidant properties that originate from the passion fruit. Sustainably-sourced, our maracuja oil is naturally rich in vitamin E and linoleic acid, renowned for its nourishing and protective qualities on the skin. The superfruit helps to leave skin looking firmer and smoother with a noticeable glow.

The intense brightening power of C-Tetra Luxe is supercharged with the influence of optimised red ginseng. With incredible abilities as a potent tyrosinase-inhibitor, the botanical component works with vitamin C to restore the appearance of skin’s natural radiant, even tone.

All of the above technologies are delivered with ease in a silky squalane-base combined with vitamin F to envelope the complexion in total nourishment that feels rich with moisture all day long, while helping to nurture the skin's natural barrier.

THE SCIENCE BEHIND

“C-Tetra Luxe is the pinnacle of our C-Tetra range. Containing double the amount of tetrahexyldecyl ascorbate and an infusion of radiance boosting antioxidants delivered in a nourishing squalane base, C-Tetra Luxe is the perfect all-rounder in our vitamin C range. We recommend this to the majority of skin types including those looking for intense anti-ageing results, drier and dehydrated skin types, and those looking for a powerful antioxidant serum that remains gentle on the skin despite its high concentration of vitamin C."

Daniel Isaacs, Medik8 Director of Research

Best lights you can get for the best pricing!
Color: 5in Round LED Pod, Color: 5in Round LED Pod
I have had man different off road lights over the years for many different vehicles. Let me tell you about these 5” aux beams. I ordered these lights to go on my 2500 as ditch lights and I am beyond impressed! The lights showed up well packaged. When opening the box, the instructions where right on top and by far one if the easiest sets of instructions I’ve had for wiring diagrams. The lights were packaged and wrapped in foam all the way around to protect them from shipping. The wrapping of the lenses for scratch prevention was perfect. The included wiring harness was packed in a bag and laid out very easily for installation. The harness hooked to the battery and then to the lights with easy quick connects and had more than enough length to put the lights anywhere. Once they were mounted and installed I hooked them up to my aux beams switch panel with ease. Now for the lights! The brightness is beyond bright enough to see miles away! These lights will shine anything you could ever want to see. The spot flood combo work exceptionally well for all situations and darkness. The side shooter stretch them beam out to the sites and can see all the way across. The running lights tie in very easy with your turn signals for extra turn lights or running lights. Heavy duty is an understatement for the quality of these lights. I’m still running them after several months with no water intrusion and still as bright as the day I installed them. The price for what you get, is far beyond better than other top brands! I will be buying more of these for my next off roading set up!

Too big for a tiger, but works well on the fiddy
Color: 4*2.5in Cube LED Pod
Not as bright as the graph says they are, or maybe I'm not in a dark enough area at night. But they definitely are blinding. Were too big for my adv bike unfortunately, but they work good on my truck as ditch lights. Not too bulky looking like the cubes are and no wind noise that I can hear. Definitely lights up the wma trails and the side shooters are very helpful. I will note though that as soon as your hood gets dusty it becomes blinding from the inside side shooters though. so I painted the yellow lens cover on the inside sides and it helps a lot with the hood glare.
