Ascorbyl Glucoside
A stabilised Vitamin C derivative.
Ascorbyl Glucoside provides antioxidant support while helping promote:
Brightness + radiance + more even-looking skin tone.
It is a useful alternative to formulations based solely on pure Ascorbic Acid and fits particularly well into a daily preventative skincare routine.
Ethylbisiminomethylguaiacol Manganese Chloride / EUK-134™
One of the most distinctive ingredients in this formula.
EUK-134™ is a synthetic manganese-based antioxidant molecule designed to mimic the activity of the body's antioxidant enzymes:
Superoxide Dismutase + Catalase.
Its role is to help neutralise reactive oxygen species generated by environmental stress.
For Chris & Alley, the clearest customer-facing positioning is:
Advanced antioxidant technology that helps strengthen the skin's defence against oxidative environmental stress.
It should not be confused with sunscreen and does not replace daily SPF.
Ferulic Acid
A potent antioxidant frequently combined with other antioxidant actives.
Within NTRYMED Antioxidant Serum, it complements:
Vitamin C + Vitamin E + EUK-134™
to provide a more comprehensive antioxidant system.
Tocopherol / Vitamin E
A lipid-soluble antioxidant helping support the skin's defence against oxidative stress.
Vitamin E also provides complementary skin-conditioning benefits and works particularly well as part of a multi-antioxidant formulation.
Niacinamide
A multifunctional form of Vitamin B3 supporting:
Skin barrier function + more even-looking tone + hydration + skin resilience.
Its inclusion gives the serum benefits beyond antioxidant protection alone.
Sodium Hyaluronate
A form of Hyaluronic Acid that attracts and retains moisture.
It helps improve:
Hydration + suppleness + softness + visible plumping.
Panthenol
Pro-Vitamin B5 provides hydrating and soothing support.
It helps maintain skin comfort and complements the serum's barrier-supportive ingredients.
Betaine
A moisture-supporting osmolyte that helps maintain skin hydration and comfort.
It complements Sodium Hyaluronate and Glycerin within the serum's humectant system.
Squalane
A lightweight, skin-compatible emollient that helps soften the skin and support the lipid barrier.
Centella Asiatica Extract
A well-established soothing botanical providing antioxidant and skin-conditioning support.
It is particularly useful when environmental stress leaves the skin feeling less comfortable or resilient.
Camellia Sinensis / Green Tea Extract
Rich in antioxidant polyphenols.
Green Tea helps support the skin's defence against oxidative environmental stress and complements the formula's broader antioxidant complex.
Polygonum Cuspidatum Root Extract
A botanical extract commonly valued for its antioxidant polyphenol content.
It contributes additional free-radical defence within the botanical complex.
Scutellaria Baicalensis Root Extract
Provides complementary antioxidant and skin-conditioning support.
Glycyrrhiza Glabra / Licorice Root Extract
Supports:
Visible soothing + brighter-looking skin + more even-looking tone.
This makes it particularly complementary to the Vitamin C and Niacinamide components.

Provides soothing and skin-conditioning support.
Rosemary Leaf Extract
Provides additional botanical antioxidant support.
Lecithin + Hydrogenated Lecithin
