ALASTIN C-RADICAL Defense Antioxidant Serum is a multi-award-winning vitamin C serum that delivers 15 proven antioxidants to defend skin against environmental damage while supporting your skin's ability to conserve elastin and build collagen. Unlike traditional vitamin C serums that can degrade quickly, this formula uses a proprietary encapsulated sodium ascorbate that absorbs 20 times more effectively than standard delivery systems, giving your skin sustained protection against free radicals, UV exposure, blue light, and pollution. In clinical studies, it reduced the effects of free radicals in skin by up to 74%.
Key Benefits:
Powerful Free Radical Defense: A proprietary encapsulated sodium ascorbate, a remarkably stable form of vitamin C, absorbs 20x more effectively to reduce the effects of free radicals in skin by up to 74% in clinical testing.
Visible Texture Refinement: Clinical studies showed up to a 71% reduction in the appearance of uneven skin texture in as early as 8 weeks, supported by centella asiatica extract and physalis angulata extract to help calm and repair.
Fine Line and Wrinkle Reduction: Collagen-supporting ingredients like ubiquinone and carnosine work alongside vitamin C to deliver up to a 50% reduction in the appearance of fine lines in 8 weeks.
Redness and Discoloration Correction: Bisabolol, green tea (camellia sinensis leaf extract), and ergothioneine help visibly reduce redness by up to 69% while fading the look of brown spots and photodamage.
Deep Antioxidant Layering: Fifteen antioxidants, including ectoin, pomegranate fruit extract, olive leaf extract, ginger root extract, and dunaliella salina extract, create a comprehensive shield against UV, blue light, and pollution damage.

If your skin shows signs of environmental stress, whether that looks like dullness, uneven texture, redness, brown spots, or fine lines that seem to deepen with sun exposure, this serum was built for you. It is especially well suited for anyone who has tried vitamin C serums in the past but been frustrated by oxidation, instability, or irritation.
Ideal for most skin types, including sensitive skin. The encapsulated vitamin C delivery system and calming botanicals like bisabolol and physalis angulata make this a strong choice if traditional L-ascorbic acid formulas feel too harsh on your skin.
Also a smart addition if you spend significant time in front of screens or outdoors and want daily defense against blue light, pollution, and UV-generated free radical damage.
-
Apply this serum to slightly damp skin right after cleansing. The encapsulated sodium ascorbate benefits from a thin layer of moisture to help it glide and absorb more evenly, giving you better antioxidant coverage across every area of the face.
-
Apply: After cleansing, dispense 1-2 pumps of serum onto fingertips and smooth evenly across the face, avoiding the eye area.
Frequency: Use every morning and evening. In your morning routine, follow with sunscreen for maximum environmental protection.

What makes the vitamin C in ALASTIN C-RADICAL Defense Antioxidant Serum different from other vitamin C serums?
This serum uses a proprietary encapsulated sodium ascorbate rather than traditional L-ascorbic acid. This form is remarkably stable, meaning it resists oxidation and degradation, and it absorbs 20 times more effectively than standard vitamin C delivery systems. That translates to stronger, longer-lasting antioxidant protection without the irritation or rapid breakdown common with conventional vitamin C formulas.
How long does it take to see results with ALASTIN C-RADICAL Defense Antioxidant Serum?
In clinical studies, participants saw measurable improvements in as early as 8 weeks, including up to a 71% reduction in uneven texture, up to a 69% reduction in redness, and up to a 50% reduction in fine lines. Consistent twice-daily use is key to achieving these results.
Can ALASTIN C-RADICAL Defense Antioxidant Serum help with hyperpigmentation and dark spots?
Yes. The encapsulated sodium ascorbate helps brighten skin and reduce the appearance of brown spots and photodamage. Combined with antioxidants like green tea extract and pomegranate extract that target oxidative stress, this serum works to even out skin tone over time with consistent use.
Is ALASTIN C-RADICAL Defense Antioxidant Serum safe for sensitive skin?
This serum is formulated for most skin types, including sensitive skin. The encapsulated delivery system releases vitamin C gradually, which reduces the risk of irritation. Calming ingredients like bisabolol, ectoin, and physalis angulata extract further help soothe and protect reactive skin.
Does ALASTIN C-RADICAL Defense Antioxidant Serum protect against blue light damage?
Yes. The formula includes 15 proven antioxidants specifically designed to help neutralize free radicals generated by UV exposure, blue light from screens, and environmental pollution. Daily use helps shield skin from the cumulative damage these stressors cause, including premature aging and dullness.
Can I use ALASTIN C-RADICAL Defense Antioxidant Serum with retinol?
Yes, many people use this serum alongside retinol. A common approach is to apply the C-RADICAL serum in the morning for antioxidant defense and use retinol in the evening. If you prefer to use both at night, apply the serum first, let it absorb, then follow with retinol. If you have any concerns about layering actives for your specific skin, our estheticians can help through a free skincare consultation.
How many antioxidants does ALASTIN C-RADICAL Defense Antioxidant Serum contain?
This serum contains 15 proven antioxidants, including encapsulated sodium ascorbate, ubiquinone (CoQ10), ergothioneine, ectoin, carnosine, green tea extract, pomegranate extract, olive leaf extract, ginger root extract, dunaliella salina extract, and tocopherol. Together they create a comprehensive defense network that targets free radicals from multiple pathways.
