Free radicals and aging

In the field of health and beauty, we often talk about “free radicals”, and this term is most often used when it comes to diets, skin aging, oxidative stress and various diseases. 

How do they form? And what are the consequences of their accumulation in our body?

What are free radicals?

Free radicals are very reactive molecules needed to perform certain functions and maintain health.

How do they form?
They are produced every day in our body, as a result of biological processes in cells. Every day this set of processes takes place in the body and can be included in “cellular respiration”. These processes are necessary for cell life, but the production of free radicals over time can have negative effects as they alter cell membranes and genetic material (the cell’s DNA). 

What are the consequences of their accumulation?

Free radicals live for microseconds, but have the ability to affect everything around them. Therefore, the uncontrolled production of free radicals is harmful to our health. To prevent it, we must follow a few simple rules:

  • eat healthy foods
  • avoid smoking, alcohol, processed foods, pesticides, stress, negative emotions, solar radiation
  • lead an active lifestyle.

In this way, we will help minimize and neutralize free radicals. 


What is an antioxidant?

 An antioxidant is a molecule capable of inhibiting oxidation caused by free radicals or oxidative stress.

What is its function?

Antioxidants are responsible for neutralizing free radicals, and protect us from their harmful effects on cells. 
We can get them through certain foods and nutritional supplements, medical cosmetics, mainly in the form of vitamins (natural antioxidants) that include:

     – Vitamin A (beta-carotene) – once in the body, beta-carotene is converted into vitamin A, necessary for maintaining mucous membranes and healthy skin. On the other hand, it should be emphasized that beta-carotene is a safe source of vitamin A, because the body stops converting beta-carotene when there is no need for this vitamin.

     – Vitamin C – helps the body produce collagen and restore tissues. In skin care products, it provides protection against aging and pigmentation

      – Vitamin B3 (niacinamide) – helps control sebum production, redness and skin irritations. It also inhibits melanin in the dermis to prevent severe sunspots and acne

– Vitamin E – helps improve skin texture by maintaining cell balance. Suitable for dry, withered skin, as a result of hormonal or climatic changes.

Antioxidants for the skin are essential to keep it healthy and balanced, maintaining its properties such as elasticity, softness, hydration and a radiant complexion. Free radicals affect the epidermis internally and externally and oxidize it.
Fortunately, there are ways to combat this process, such as a healthy lifestyle and restorative, antioxidant-enriched cosmetic and dermatological treatments.
