Glow Definition
In skincare, reactive oxygen species — often abbreviated as ROS — are unstable molecules that form when the skin encounters external stressors like UV exposure, pollution, or internal oxidative processes. They fall under the broader category of free radicals, and while naturally occurring, excess ROS can interfere with surface balance by reacting with lipids and proteins near the skin’s outermost layers.
Although ROS are invisible and often misunderstood, they’re part of the environmental equation that many modern antioxidant formulas aim to help manage. Think of them not as something to fear, but as a context for understanding why certain ingredients — like resveratrol, vitamin C, or niacinamide — show up in your glow routine.

Why It Matters
Understanding ROS is key to making sense of why certain ingredients show up again and again in glow-supportive routines. These molecules don’t just float around aimlessly — they can interact with the skin’s surface, especially its lipid barrier, which helps explain the rising popularity of antioxidant-rich products in routines aiming to maintain balance and luminosity.
Rather than chasing after “anti-aging” promises, thinking in terms of oxidative balance (and how ingredients play into it) offers a more grounded way to support the skin’s visible clarity, tone, and resilience.

Why We Love It For Glow
We don’t love reactive oxygen species in skincare. But understanding it gives context to why antioxidant-rich products are so central in modern glow routines. Rather than chasing trends, this concept helps connect the dots between daily environmental exposure — like UV and pollution — and how they can influence skin dullness, visible fatigue, or long-term glow potential.
It’s not about “eliminating” ROS, but learning how your routine can help offset their everyday effects. Supporting skin with barrier-reinforcing and antioxidant-rich layers is one of the most practical ways to sustain radiance over time — especially if glow is your non-negotiable.

FAQ
What’s the difference between free radicals and reactive oxygen species (ROS)?
Reactive oxygen species (ROS) are a specific type of free radical that involve oxygen-containing molecules. While all ROS are free radicals, not all free radicals are ROS. In skincare conversations, the terms are often used interchangeably to describe molecules that may affect skin stability, especially when discussing external aggressors or antioxidant formulas.
Do antioxidants in skincare help address ROS?
Antioxidants are often included in formulations to help maintain balance when skin is exposed to environmental stressors that may generate ROS. While they don’t eliminate ROS, they may play a role in stabilizing the visible effects of oxidative stress on the surface of the skin.
Are ROS only a concern for aging skin?
ROS are relevant for all skin types, not just aging. Their formation can be triggered by sun exposure, pollution, or other environmental factors that affect skin appearance over time. Building a routine that supports surface resilience is beneficial at any stage.
