Skin aging – what are the causes and how to prevent it?

Skin aging is the result of two aging processes that complement each other:


Internal or constitutional aging is individual for each person, it is genetically programmed and occurs gradually;
External aging caused by external factors is controllable and is associated with premature skin aging.
What are the signs of skin aging?

With age, the renewal of epidermal cells slows down.


The epidermis becomes thinner, and the stratum corneum, consisting of superficial dead cells, thickens.


This leads to the appearance of dehydrated skin with enlarged pores and pigmentation disorders.


The dermis, which contains elastic and collagen fibers, also suffers from signs of aging.


These fibers change, reducing the production of hyaluronic acid, which makes the skin less elastic and leads to wrinkles.


Signs of skin aging that are exacerbated by sunlight:

Dark spots from hyperpigmentation;
Relaxation of the skin;
skin dehydration;
thinning of the skin;
actinic keratosis.
Actinic keratoses are precancerous lesions and their presence requires close dermatological monitoring.


Actinic keratoses are local thickenings of the skin covered with scales.


They appear as age spots on sun-exposed areas such as the back, arms, and face.


What are the causes of skin aging?

Sunlight is the main factor in skin aging.


Prolonged exposure to the sun leads to premature aging of the skin.


UV rays affect skin cells by breaking their DNA chain and thereby causing changes in cell renewal and the production of melanin, collagen and elastin.


They contribute to the strengthening of the physiological processes of aging, which leads to the appearance of less elastic, dry, dehydrated, and wrinkled skin.


Fair-skinned people will have greater and earlier exposure to the sun than darker-skinned people due to less protective melanin.


There are many differences in the phenomenon of skin aging in different people, as well as a genetic predisposition to earlier aging.


Smoking also causes wrinkles due to the destruction of the elastic fibers of the skin.


The skin loses its radiance, its color becomes gray, and healing processes are disrupted.


stress and pollution
Stress and environmental pollution also disrupt cell function, slow down cell renewal, and destroy hyaluronic acid, which is responsible for skin tone and hydration.


Stress and environmental pollution are associated with an increase in the secretion of free radicals – substances that are produced by the body and are responsible for the aging process and cell damage.


Passive lifestyle
A sedentary lifestyle, a poor diet low in antioxidants and essential fatty acids, alcohol and lack of sleep also play a role in the skin aging process.


Female sex hormones play an important role in skin hydration. This is why the skin becomes drier during menopause.


How to protect our skin from aging?

Sun protection and regular use of sunscreen help to avoid accelerating the premature aging process;
Moisturizing the skin – proper hydration is an effective preventive measure that can prevent accelerated aging;
taking enough fluids regularly throughout the day;
Antioxidant foods help prevent skin aging;
Balanced and varied diet;
Quit smoking – after quitting smoking, the skin quickly restores its appearance and elasticity;
to handle the stress;
Full sleep.
