Glow Definition
Free radicals in skincare refer to unstable molecules that form as a result of environmental stressors like UV exposure, pollution, or blue light. These molecules are often associated with oxidative stress in the skin — a process that may influence how radiance shifts and how the glow cycle unfolds over time.
To help buffer against this, many routines include antioxidants like vitamin C, glutathione, or polyphenols to help neutralize free radicals before they overwhelm the skin’s natural defenses. While the science behind them runs deep, in glow routines, the concept is simple: protection matters just as much as performance.

Why It Matters
Free radicals tend to show up quietly — often alongside daily stressors like UV exposure, pollution, or shifts in the environment. When they do, skin might feel less consistent, more unpredictable, or harder to read. That’s why glow routines don’t just focus on renewal — they also lean into reinforcement, adding support where skin needs it most.
This is where ingredients like vitamin C, glutathione, and other antioxidants come into focus. They’re often layered into glow routines that account for daily stressors — like pollution, travel, or sun. Paired with steps like exfoliation or hydration, they help round out the rhythm of your routine and bring balance back to your glow cycle.
GLOW TIP Apply antioxidant-rich products in the morning — especially if your routine needs daytime layering support against sun or pollution exposure.
Why We Love It For Glow
We don’t love free radicals in skincare — but we do love understanding what they mean for glow. Recognizing how oxidative stress impacts radiance is the first step in protecting your skin’s natural glow cycle.
From dullness and uneven tone to the kind of fatigue you can see in your skin, free radicals are often the quiet disruptors behind glow setbacks. When antioxidant care becomes part of your routine, it’s no longer just about reacting — it’s about creating space for glow to stay consistent.

FAQ
How do antioxidants help with free radicals in skincare?
Antioxidants like vitamin C, glutathione, and polyphenols are commonly used in skincare routines centered on antioxidant care. They don’t reverse damage, but they can help defend against it — especially when applied consistently in the morning.
What’s the best time to apply antioxidant products for free radical protection?
Most antioxidant-rich products are applied as a morning step before SPF in routines that account for daily environmental stressors. You’ll often find them in serums, essences, or lightweight moisturizers.
Can free radicals affect skin glow and radiance?
Yes — daily exposure to environmental stressors like UV or pollution can affect how glow appears over time, often coinciding with shifts in tone, texture, or radiance. Including antioxidant-rich steps in your routine helps create balance when skin feels out of sync.
