What is an antioxidant?

Our skin is exposed to sunlight, air pollution, cigarette smoke, and even daily stress factors throughout our lives. All these factors lead to the formation of free radicals. Free radicals, in turn, damage cells and create oxidative stress, which leads to problems such as premature aging, wrinkles, spot formation, and inflammation in the skin.

This is precisely where antioxidants play a critical role in the body's and skin's natural defense mechanism. Antioxidants are effective against free radicals. They neutralize these free radicals, preventing cell damage. This is important not only for the skin but also for general health. The protective effects of antioxidants are also mentioned in cardiovascular diseases, neurological diseases such as Alzheimer's, and certain types of cancer.

What are the benefits of antioxidants for the skin?

The main effects of antioxidants on the skin are:

  • Makes the skin more elastic and healthy.

  • Reduces the appearance of spots, evens out skin tone.

In which skin diseases do antioxidants provide benefits?

Eczema (Atopic Dermatitis):

Thanks to their anti-inflammatory effects, antioxidants can alleviate redness and itching by reducing inflammation symptoms seen in eczema.

Psoriasis:

Balancing free radical levels can reduce plaque formation and scaling.

Rosacea:

Antioxidants such as EGCG, Vitamin C, and niacinamide can help reduce symptoms such as redness and prominent vessel appearance seen in rosacea.

Which foods contain antioxidants?

Antioxidants obtained through diet help reduce free radical damage in all body systems, including the skin.

Blackberries, pomegranates, blueberries: They provide strong antioxidant protection thanks to their anthocyanins and polyphenols.

EGCG (green tea extract): Reduces inflammation, suppresses redness.
