Understanding Free Radicals & Why Antioxidants Matter
Free radicals are unstable molecules that damage healthy skin cells through a process called oxidative stress. Left unchecked, this damage accelerates visible signs of aging—think fine lines, wrinkles, and uneven pigmentation.
Free radical exposure comes from multiple sources: UV radiation, pollution, and even cigarette smoke all accelerate their formation. Antioxidants work by neutralizing these molecules before they can damage skin cells, which is why they've become a cornerstone of preventive skincare.
Incorporated consistently, antioxidants can help protect skin's collagen and elastin, even out tone, and support a smoother, more resilient complexion over time.
Below, we break down why antioxidants deserve a permanent place in your routine, along with practical guidance on how to use them and which formulations to look for.
5 Dermatologist-Recommended Reasons to Use Antioxidants for Your Skin
Evens skin tone
Consistent antioxidant use helps combat sun-induced pigmentation. Vitamin C, in particular, works to inhibit excess melanin production, helping to fade discoloration and even out overall tone.
Reduces inflammation
Niacinamide is well-documented for its ability to calm inflammation and support the skin's natural repair processes. It's an especially effective addition for those managing breakouts or redness.
Enhances sun protection
Antioxidants can help boost the effectiveness of your sunscreen when layered underneath it. For best results, apply antioxidants in the morning before your SPF—and, as always, daily sunscreen use remains essential regardless of your antioxidant routine.
Combats visible signs of aging
Oxidative stress accelerates collagen breakdown, contributing to fine lines, wrinkles, and loss of firmness. Regular antioxidant use helps protect existing collagen and may support a more resilient, youthful-looking complexion over time.
Defends against pollution
Environmental stressors, particularly pollution, are a significant trigger for free radical formation. Daily antioxidant use helps mitigate this damage, offering an added layer of defense against everyday environmental exposure.
When to Use Antioxidants: Morning vs. Night
As a general rule, antioxidants are most effective in the morning, when they can help defend against free radical exposure from sun and pollution throughout the day.
That said, certain antioxidants perform best as part of an evening routine. Here's a simple breakdown:
- Morning: Vitamin C, Vitamin E
- Night: Niacinamide, Vitamin A
And a few versatile, plant-based antioxidants can be used morning or night, depending on your routine:
- Morning or Night: Resveratrol, Kakadu Plum, Green Tea, Turmeric, Super Berries

Frequently Asked Questions
What are free radicals, and why are they bad for skin?
Free radicals are unstable molecules that damage healthy skin cells through oxidative stress. Over time, this damage contributes to visible signs of aging, including fine lines, wrinkles, and uneven pigmentation.
What causes free radical damage?
Free radicals form in response to environmental stressors like UV radiation, pollution, and cigarette smoke. Because most people are exposed to these factors daily, ongoing protection is important.
How do antioxidants help?
Antioxidants work by neutralizing free radicals before they can damage skin cells. Used consistently, they help protect collagen and elastin, even out skin tone, and support a smoother, more resilient complexion over time.
Can antioxidants actually reduce pigmentation and uneven tone?
Yes. Vitamin C, in particular, helps inhibit excess melanin production, which can fade discoloration and support a more even complexion over time.
Are antioxidants good for sensitive or breakout-prone skin?
Niacinamide is a good option for those dealing with redness or breakouts, as it's known to calm inflammation and support the skin's natural repair process.
Do antioxidants replace sunscreen?
No. Antioxidants can enhance the effectiveness of your sunscreen when applied underneath it, but they don't replace SPF. Daily sunscreen use is still essential.
Can antioxidants help with existing fine lines and wrinkles?
They may help. Since oxidative stress accelerates collagen breakdown, regular antioxidant use can help protect existing collagen and support a more youthful-looking complexion over time.
When should I apply antioxidants: morning or night?
It depends on the antioxidant. Vitamin C and Vitamin E are best used in the morning, while Niacinamide and Vitamin A work well at night. Plant-based options like Resveratrol, Kakadu Plum, Green Tea, Turmeric, and Super Berries are flexible enough for either.
What's an easy way to start incorporating antioxidants into my routine?
The Go-Getter Day Serum is formulated with stabilized Vitamin C and plant-based antioxidant extracts, along with peptides and hyaluronic acid, making it a simple one-step addition to your morning routine.
