Why does your acne-prone skin need antioxidants?

The invisible science that can change your skin

Summer is here. Sun, heat, longer days, "vitamin D" and golden skin. Everything seems great... except your skin.
If you have oily or acne-prone skin, you'll have noticed:

More frequent outbreaks.
More visible redness.
Brands that take longer to disappear.
Feeling of constant inflammation.

There is a cause behind these symptoms: oxidative stress, a biological process that can significantly worsen inflammatory skin conditions.

And yes, you can fight it, with the help of a very special category of ingredients: antioxidants.

What are free radicals and why do they damage acne-prone skin?

Every day, your skin faces multiple aggressors:

UV radiation
Environmental pollution
Intense heat
Sweat
Smoking, stress, poor diet

All these factors cause the formation of free radicals: unstable molecules that have lost an electron and seek to regain it by attacking healthy skin cells.

In acne-prone skin, this translates to:

Persistent inflammation
Microbiome alteration
Oxidation of sebum → more comedones
More difficulty in regenerating
Appearance of post-inflammatory marks

What is oxidative stress and how does it affect your skin?

From a cellular perspective, imagine each skin cell as a house protected by walls. Free radicals are like thieves trying to break them down to steal what they need.

This imbalance creates a vicious cycle:
More free radicals → more damage → more inflammation → more free radicals.

This phenomenon is directly related to:

Inflammatory acne
Sensitivity and redness
Premature aging
Difficulty in skin repair

Antioxidants: a key defense against oxidative stress

Antioxidants are molecules capable of donating an electron without becoming unstable, neutralizing free radicals and cutting off that chain of damage.

For oily, sensitive, or acne-prone skin, antioxidants:

They reduce inflammation
They prevent sebum oxidation (key to avoiding comedones)
They improve the barrier function
They accelerate regeneration
They brighten the tone
They enhance the effectiveness of sunscreen.

Is sunscreen not enough?

Sunscreen is essential, yes. But it doesn't completely block the formation of free radicals.
Besides:

Some sunscreens can oxidize under UV radiation and generate more free radicals.
Pollution, heat, stress, and tobacco also generate oxidative damage that sunscreen cannot stop.

That's why real protection starts with antioxidants. They are the essential complement for balanced and resilient skin.

Recommended antioxidants for acne-prone skin

Niacinamide (Vitamin B3)

EGCG (epigallocatechin gallate, from green tea)

Powerful natural antioxidant and anti-inflammatory
It regulates sebum production without drying out the skin.
Soothes irritated skin and reduces redness

Resveratrol (grape extract or Japanese knotweed)

Polyphenolic antioxidant with strong anti-inflammatory action
Protects against UV-induced oxidative damage and pollution
It helps reduce outbreaks related to chronic inflammation.
It promotes cell regeneration

Stabilized Vitamin C

It neutralizes free radicals and protects against photoaging.
Lightens post-inflammatory spots (acne marks)

Habits that help reduce oxidative stress

Diet rich in antioxidants: fruits, vegetables, seeds, nuts.
