Have you noticed that your skin looks duller after a week of stress, pollution, and little rest?
That visible tiredness isn't accidental: it's the result of a silent process that occurs in every skin cell and determines how your skin ages. It's called oxidative stress , and understanding it is the first step to preventing premature aging.
In this article you will discover what it is, how it is produced, why it damages cellular structures, and how modern biotechnology can counteract it.
What is oxidative stress?
Oxidative stress is an imbalance between the production of free radicals (unstable molecules generated by external and internal factors) and the body's ability to neutralize them through antioxidants .
On the skin, this process happens every day: when you are exposed to the sun, urban pollution, tobacco, psychological stress, or unbalanced diets.
When free radicals exceed the natural antioxidant capacity, they begin to damage lipids, proteins, and cellular DNA , generating inflammation, loss of elasticity, and visible aging.
In simple terms: oxidative stress is the biological oxidation of your cells , the same phenomenon that causes an apple to oxidize upon contact with air.
How does oxidative stress affect the skin?
Oxidative damage directly impacts the function and structure of the skin.
Its main effects are:
DNA damage and premature aging
Free radicals alter the DNA of keratinocytes and fibroblasts, reducing the capacity for cell regeneration.
This accelerates the appearance of early wrinkles and pigment spots .
Loss of collagen and elasticity
Excessive oxidants degrade collagen and elastin, causing sagging and uneven texture .
Imbalance in the skin barrier
Oxidative stress weakens protective lipids, resulting in dry, sensitive, and inflammatory skin .
Increased sensitivity to UV radiation
Oxidized skin responds worse to the sun: it suffers more photodamage and sun aging.
Factors that generate cutaneous oxidative stress
Environmental factors include UV radiation, pollution, smoke, and climate change. These factors generate a significant increase in free radicals in the skin and trigger chronic inflammation.
Biological factors, such as stress, lack of sleep, and natural aging, lead to a decrease in endogenous antioxidants, reducing the skin's natural defenses.
Lifestyle factors include poor diet, alcohol consumption, and smoking. These habits increase internal oxidative processes, accelerating cellular damage.
Digital factors: primarily constant exposure to blue light from screens. This type of radiation causes mitochondrial oxidation and contributes to skin fatigue.
Skin aging depends not only on time, but also on the level of accumulated oxidative stress.
The latest research in molecular dermatology shows that more than 80% of visible aging comes from external oxidative factors.
Therefore, modern cosmetics no longer just seek to hydrate, but to educate the skin to resist and repair itself.
At Rabbits & Dragons , this principle is the basis of the Pre-Aging Skincare approach: preventing rather than correcting, taking care of cellular function and restoring its natural energy.
Signs that your skin is suffering from oxidative stress
-
Opacity and uneven tone.
-
Appearance of premature fine lines.
-
Feeling of dryness or tightness.
-
Mild inflammation or redness.
-
Lack of brightness and persistent “tiredness”.
If your skin shows several of these signs, it is probably under oxidative fatigue , and needs active antioxidants and cellular rest.
Oxidative stress is silent, but its effects are visible.
Preventing it means protecting the skin from its environment , restoring its balance and maintaining its long-term vitality.
Science has shown that skin protected from oxidation not only ages more slowly , but also reflects internal well-being.
