Skincare has developed a language all its own.
We hear words like free radicals, oxidative damage, antioxidants and skin barrier so often that they begin to feel familiar, even when we aren’t entirely sure what they mean. We know antioxidants are supposed to be good. We know free radicals are something we should avoid. And lately, nearly every product seems to promise support for the skin barrier.
But what is actually happening within our skin? And what role can skincare realistically play?
At Nektar, we believe understanding your skin is part of caring for it. Not because you need to become an expert in skin biology, but because knowledge allows you to make thoughtful choices without being driven by fear, exaggerated promises or the idea that your skin is a problem waiting to be corrected.
So, let’s slow down and make sense of some of the language.
What Are Free Radicals?
Free radicals are unstable molecules created naturally within the body and through exposure to the world around us.
Molecules generally prefer to exist in balance. A free radical is missing an electron, so it attempts to stabilize itself by taking one from another molecule. When this happens repeatedly, it can begin a chain reaction that disrupts healthy cells and some of the structures that help our skin remain strong and resilient.
Free radicals are not foreign invaders, and they are not entirely bad. Our bodies produce them during ordinary processes such as metabolism and immune activity, and in balanced amounts, they have important work to do.
The concern arises when free-radical activity becomes greater than the body’s natural defenses can comfortably manage.
Sunlight is one of the most significant sources, but pollution, wildfire smoke, cigarette smoke, stress, poor sleep and other environmental pressures can also contribute. Our skin is the place where our inner world meets the outer one, so it is constantly responding to what surrounds us.
When the balance between free radicals and the body’s defenses is disrupted, we call it oxidative stress.
Oxidative Stress and Oxidative Damage
Although these terms are often used interchangeably, they are not quite the same.
Oxidative stress is the imbalance itself. Oxidative damage is the effect that imbalance can have over time.
You have probably heard oxidation compared to an apple turning brown after it is cut. It isn’t a perfect comparison; our living skin is far more complex and has its own protective and restorative systems, but it offers a simple picture of how ongoing exposure to oxygen and the environment can gradually create change.
Within the skin, oxidative stress can affect lipids, proteins and collagen. Over time, it may contribute to increased dryness or sensitivity, uneven-looking tone, dullness and changes in elasticity and texture. It can also place additional strain on the skin’s protective barrier.
That does not mean every change we see in our skin is “damage,” nor does it mean we should fear sunlight, the environment or the passage of time.
Our faces are meant to change. They carry expression, experience, laughter, grief, growth and years of being alive. Caring for oxidative stress is not about trying to preserve ourselves in one moment forever. It is about helping the skin remain as healthy, comfortable and resilient as possible while it continues its natural journey.
That distinction matters deeply to us.
Where Antioxidants Come In
Antioxidants help the body manage free-radical activity. They can stabilize free radicals and interrupt some of the chain reactions that might otherwise affect healthy cells.
Our bodies create their own antioxidants, and we receive many others through the foods we eat. Antioxidant-rich ingredients can also be applied topically to help support the skin where it encounters the outside world.
Plants are a beautiful source of these compounds. Because they cannot step out of the sun, move away from harsh weather or escape environmental stress, plants have developed complex protective systems of their own. Many contain naturally occurring vitamins, carotenoids, polyphenols and other antioxidant compounds.
When we formulate with antioxidant-rich botanical oils and extracts, we are drawing upon some of those plant compounds to offer the skin another source of support.
This is present throughout Nektar’s skincare collection.
Our Rejuvenating Serum brings together argan, sea buckthorn and moringa oils. Along with their nourishing fatty acids, these oils contain naturally occurring antioxidant compounds that help support skin exposed to the day’s environmental stressors.
Our Active Night Serum combines bakuchiol with astaxanthin, a richly pigmented carotenoid antioxidant. We created it as an evening companion for the skin—a way to replenish and nurture it after a day spent meeting sun, weather, pollution and everything else in our environment.
Antioxidants are not an invisible force field, and no serum can prevent every form of environmental damage. Daily sun protection still matters, as do sleep, nourishment, hydration and the ways we care for the whole body.
Botanical skincare is one part of that larger relationship.
What Is the Skin Barrier?
The skin barrier is the outermost part of our skin and its first line of protection.
It is often described as a brick wall. The skin cells act as the bricks, while a mixture of lipids, including ceramides, cholesterol and fatty acids, create the mortar holding them together.
When this structure is functioning well, it performs two essential jobs: it helps keep precious water inside the skin, and it helps keep irritants, pollutants and unwanted microorganisms out.
This barrier is not simply a layer sitting on top of us. It is alive, responsive and continually adapting. It responds to our environment, our skincare practices, hormonal shifts, stress and the changing seasons of our lives.
When the barrier is depleted or disrupted, water escapes more easily through the surface. Skin may begin to feel tight, dry, rough, flaky, itchy or unusually sensitive. Products that have always felt comfortable may suddenly sting. Sometimes, the skin may even produce more oil in an attempt to compensate for what it is lacking beneath the surface.
Our instinct is often to do more, to exfoliate the roughness away, add another active ingredient or search for a stronger treatment. But skin that is struggling does not always need to be pushed harder.
Sometimes it needs gentleness. Sometimes it needs simplicity. Sometimes it needs us to stop fighting it long enough to listen.
What Does the Skin Barrier Need?
Harsh cleansers, very hot water, aggressive exfoliation, dry weather, smoke, pollution and layering too many strong active ingredients can all disrupt the barrier.
Supporting it begins with protecting the things that are already part of its natural structure: water and lipids.
Water-based hydration helps replenish moisture, while lipid-rich emollients help soften the skin and slow that moisture from escaping. This is the intention behind pairing our Hydrating Facial Toner with one of our botanical facial serums.
The toner bathes the skin in lightweight hydration from rose and calendula hydrosols. Applying a facial oil while the skin is still slightly damp helps replenish the surface with nourishing lipids and hold on to that hydration.
Hydration first. Nourishment second.
It is a simple ritual, but simplicity does not mean it is insignificant. Practiced consistently, these small acts create an environment in which the skin is better supported in doing the work it already knows how to do.
How It All Connects
Free radicals, oxidative stress, antioxidants and the skin barrier are not separate skincare trends. They are parts of the same story.
Our skin is constantly interacting with the world. Free radicals are part of that interaction. When their activity exceeds the skin’s defenses, oxidative stress can occur. Antioxidants help support those defenses, while hydration and replenishing lipids help care for the barrier that holds moisture in and offers protection from the outside.
No single ingredient does everything, and no product can promise skin that never changes.
Nor should it.
At Nektar, we are not interested in waging war against time or asking women to view every line, spot or shift in texture as evidence that something has gone wrong. We are interested in helping you understand what your skin needs and giving you beautiful, botanical ways to meet those needs.
Skincare can be both practical and deeply personal. It can support the physical function of the skin while also becoming a moment to pause, breathe and return to yourself.
Your skin has carried you through every season of your life. It protects you, communicates with you and changes alongside you.
The purpose of skincare is not to silence that story. It is to care for the skin telling it.
