About the product

Illuminate and protect your skin with our daily dose of antioxidant protection. Shielding the skin from damaging free radicals caused by pollution and UV rays, this potent serum delivers instant radiance whilst helping to preserve collagen levels and prevent accelerated ageing. 

A staple for keeping your skin healthier for longer, The Antioxidant bolsters your skin's defences, reinforces your barrier and reduces the appearance of fine lines, wrinkles, hyperpigmentation and uneven skin texture for a smoother, brighter complexion.

The advanced formula combines a highly stable, effortlessly absorbed form of vitamin C amplified by acetyl zingerone, a next-generation antioxidant, alongside acetyl tetrapeptide-2 and green tea extract to enhance performance and provide supreme environmental protection.

Key ingredients

Tetrahexyldecyl Ascorbate - Renowned for its stability and great affinity for skin, which aids penetration, this vitamin C precursor is a powerful antioxidant and tyrosinase inhibitor that helps protect the skin's collagen levels, reinforce the skin barrier and prevent hyperpigmentation.

Acetyl Zingerone - A next-generation antioxidant that works synergistically with tetrahexyldecyl ascorbate to boost its efficacy, helping to further reduce signs of photoageing and improving the skin's defences.

Fermented Green Tea Seed Extract - A fermented plant extract naturally rich in antioxidant phenols and tocopherols (vitamin E) to help protect the skin from free radical damage.

Acetyl Tetrapeptide-28 - A brightening peptide that is shown to boost the skin's antioxidant ability, shielding it from the effects of pollution and visibly reducing the appearance of dark spots and the signs of ageing.

How to refill
You’ve finished your product and received your Refill—what’s next? Simply unscrew the outer glass bottle, remove the lid and then untwist the existing inner Refill from the pump. Place the empty inner Refill bottle to one side and wash and dry your pump. Unscrew the lid on your new Refill, placing the lid to one side. Insert and tighten your new Refill bottle onto the clean pump, ensuring this is secure and tight enough that it doesn't move. This will enable the airless technology to be driven up through the pump and dispense as it should. Then, simply reattach the outer glass bottle.

Wash, dry and recycle the empty inner Refill bottle and new refill cap as appropriate. Please check requirements and capabilities locally before disposal.

FAQs

Where should I use The Antioxidant in my routine?

The Antioxidant should be used in the middle your routine at the serum stage.

The primary function of an antioxidant is to help protect the skin from environmental aggressors, placing it firmly in the Protect category.

What are free radicals and antioxidants?

Free radicals are unstable molecules with unpaired electrons produced naturally in the body and also by environmental aggressors such as pollution, cigarette smoke and UV rays. As they are missing an electron, they're constantly on the hunt for a spare electron, which they can steal from our healthy cells, damaging them in the process. This damage, also known as oxidative stress, weakens the skin's natural defences and leads to accelerated ageing, increasing concerns such as fine lines and wrinkles, hyperpigmentation, and loss of firmness.

Antioxidants work by donating their electrons instead of those belonging to your cells (how kind!), helping to protect your skin from damage and preventing premature ageing.

What is tetrahexyldecyl ascorbate (THDA) and how is it different from other vitamin C derivatives?

THDA is a precursor to ascorbic acid (pure vitamin C), which means it can be converted to ascorbic acid once applied to the skin. It is also lipid-soluble, enabling it to penetrate the epidermis more effectively than other water-soluble derivatives. THDA is inherently more stable and gentler than ascorbic acid, which is notoriously unstable and irritating for many. This is further improved when combined with acetyl zingerone as they work synergistically together.

What percentage of vitamin C is used in The Antioxidant?

The Antioxidant contains 5% Tetrahexyldecyl Ascorbate (a highly stable Vitamin-C precursor). A high percentage is not required to elicit a skin response.
As always, when it comes to percentages, it is important to note that concentration is not a direct correlation to performance. The Antioxidant is much more than a vitamin C serum. The formula includes multiple highly effective antioxidants to amplify the performance. These include Acetyl Zingerone (shown to synergistically boost THA specifically), Acetyl Tetrapeptide-28 (shown to amplify specific antioxidant pathways) and Fermented Green Tea Seed Extract (naturally high in antioxidants).
All work together to help restore optimum antioxidant balance to the skin, and defend against environmental aggressors*.

*Clinically proven based on an independent ex-vivo clinical study.

Can I use The Antioxidant with other active Skin Rocks Products?

Yes, you can apply The Antioxidant after either of our Acids; however, you may wish to use The Antioxidant in the AM and your chosen Acid in the PM.

When pairing with our Retinoids, we recommend using your Retinoid at night and The Antioxidant during the day. This radiance-boosting duo will work beautifully together to help protect and renew your skin.
