The ABCs of Vitamin C: Why This Antioxidant Should Be a Non-Negotiable in Your Skincare Routine
The ABCs of Vitamin C: Why This Antioxidant Should Be a Non-Negotiable in Your Skincare Routine
If there’s one skincare ingredient that belongs in everyone’s regimen, it’s Vitamin C. Whether you're just beginning your skincare journey or refining a clinical-grade routine, Vitamin C is the multitasking MVP that helps protect, brighten, and firm—no matter your age or skin type.
At The Face Lab in Toronto, we believe in intentional skincare powered by evidence, and few ingredients have as much clinical backing as Vitamin C (L-ascorbic acid).
What Does Vitamin C Actually Do for the Skin?
Think of Vitamin C like your skin’s daily bodyguard—it doesn’t just boost your glow, it fights off environmental threats that accelerate aging.
Here’s what makes it a powerhouse:
- Brightens dull, uneven skin tone
- Neutralizes free radicals caused by UV rays and pollution
- Boosts collagen production to improve firmness and elasticity
- Reduces the appearance of hyperpigmentation and sun damage
- Helps prevent premature aging when used consistently
Why Not All Vitamin C Is Created Equal
The truth? Not every Vitamin C serum is effective. Like a freshly sliced orange, Vitamin C is highly unstable and oxidizes quickly when exposed to light, air, or heat.
That’s why we only recommend clinically stabilized formulations that are proven to penetrate and perform.
How to Choose the Right Vitamin C Serum
Look for these ABCs when selecting your Vitamin C:
- Active Form: Opt for
L-ascorbic acid, the most researched and potent form of Vitamin C
- Blendability: It should pair well with other active ingredients like
niacinamide,
Vitamin E, or
ferulic acid
- Clinical Formulation: Stick to
medical-grade brands with research-backed ingredients, tested pH levels, and proper packaging
When and How to Use Vitamin C
Use your Vitamin C serum every morning after cleansing, before moisturizer and SPF. It works best during the day, when your skin needs extra protection from oxidative stress.
💡 Pro tip from The Face Lab:
Layering Vitamin C under sunscreen can
amplify your UV defense, giving you better long-term protection against photoaging.
