The Multi-Award-Winning Vitamin C That Plays Nice with Every Skin Type
Most high-strength vitamin C serums make you choose between potency and comfort. Alastin C-RADICAL Defense refuses the trade-off: its encapsulated sodium ascorbate delivers vitamin C deep into the skin without the sting, stickiness, or citrus-oxidation drama — and it's clinically tested to neutralize up to 74% of free radical damage. Named New Beauty's "Best Vitamin C Serum."
- Encapsulated Vitamin C (Sodium Ascorbate) — stable, gentle, deeply delivered antioxidant power
- Green Tea Extract — reinforces environmental defense
- Physalis Angulata — helps calm visible redness
Clinically shown over 8 weeks: up to 71% improvement in uneven texture, 69% reduction in the appearance of redness, and 50% reduction in the look of fine lines — while supporting your skin's own collagen.

Smooth and light, glides on.
Love this cream. Only very little is needed as it has an adherent consistency.
This has been my go to moisturizer for my combination skin (half the year) for 2.5 years now. I used to be the girl who always had all the new and trending skincare. Now I just stick to Alumier HydraDew in the humid seasons and Alumier HydraRich in the dry seasons. Not worth switching things up when something works so well for your skin.
It works!
Good
This is the best skin care line I have used so far
I use it as a night moisturizer and it is just enough for my skin. Not too much and not too little. Perfect for night time routine.
I started using this cleanser as recommended by my dermatologist to help keep my rosacea calm. It’s pricey but it seems to be working and I haven’t experienced any breakouts from switching.
Very soothing after microneedling. Apply liberally to calm any itching!
Favorite cleanser. I have purchased it 4 times already and I tried to switch to another brand and I always end up going back to this one. I have very sensitive skin and my pores get clogged very easily. This cream cleanser is soothing and does an excellent job cleansing my face. I use it in the morning and as a second cleanse at time. A little bit goes a long way and although it doesn’t have a scent, the experience of washing your face with it is so pleasant and satisfying. I am done trying new cleansers.
Favorite SPF. I have tried so many different SPF and brands. They would be too greasy and/or sting my eyes after a few hours and/or irritate my sensitive skin and/or clog my pores. I finally found the one! Is it lightweight, non greasy, protects very well, sweat resistant, doesn’t irritate my skin or clog my pores. On top of that a little bit goes a long way. This is my third bottle and my quest for the best SPF for my skin is finally over.
Très bien marché bien et j’achèterais surement un autre
I love this product, the Vivier Sheer SPF30 Mineral tinted sunscreen. I love the creamy easy to apply non scented cream that just glides and covers light skin imperfections. I will definitely re-order again.
I love this product!Used 0.3 before and increased to 0.5 with sude effects.
This cleanser polish is a povely

Alastin C-RADICAL Defense: Vitamin C Power Without the Vitamin C Problems
Traditional L-ascorbic acid serums demand a tolerance most skin doesn't have — stinging, instability, oxidation to orange sludge.

New Beauty's Best Vitamin C Serum winner, and the version sensitive skin can finally keep. WeDoSkin.ca is an authorized Canadian Alastin retailer.

The Award-Winning Vitamin C for Every Skin Type: Frequently Asked Questions
What does Alastin C-RADICAL Defense Antioxidant Serum do?
It is a clinically tested vitamin C serum that helps neutralize up to 74% of free-radical damage while brightening skin, refining texture, calming redness and supporting collagen — winner of New Beauty's Best Vitamin C Serum award.
How is it different from traditional vitamin C serums?
It uses encapsulated sodium ascorbate instead of raw L-ascorbic acid. That means no sting, no rapid oxidation, and deeper delivery — the benefits of vitamin C without the sensitivity tax.
What results does the clinical data show?
Over 8 weeks: up to 71% improvement in uneven texture, 69% reduction in the appearance of redness, and 50% reduction in the look of fine lines.
Can sensitive or redness-prone skin-prone skin use it?
Yes — that is its superpower. The encapsulated form plus Physalis Angulata calming extract make it one of the few potent vitamin C serums reactive skin tolerates daily.
When should I apply it?
Morning and evening, 1–2 pumps on clean skin before moisturizer. Morning use pairs naturally with mineral SPF for a complete environmental defense system.
Can I use it with retinol or A-Luminate?
Yes. C-RADICAL in the morning and Renewal Retinol at night is a classic pairing, and A-Luminate layers with it for accelerated brightening.
Will it oxidize and turn orange like other vitamin C?
No — encapsulation protects the vitamin C from air and light degradation, so the last pump is as potent as the first.
Where can I buy authentic C-RADICAL Defense in Canada?
WeDoSkin.ca is an authorized Canadian Alastin retailer. C-RADICAL Defense Antioxidant Serum is $218 CAD, fresh and authentic.
