The skin aging process is a complex biological process that depends on intrinsic factors (genetic due to the passage of years) as well as external factors (environmental). 

External factors that accelerate skin aging are, firstly, exposure to ultraviolet radiation and, secondly, smoking. On the other hand, new studies demonstrate that diet also plays a significant role in preventing skin aging. Diets high in simple sugars and low in vegetables, antioxidant-rich fruits, and high-quality protein will have detrimental effects on the skin. It is equally important to provide the body with a source of healthy fats to renew the skin's cell membranes, which are rich in fatty acids. Stress, and especially sleep disturbances experienced by a large part of the population, lead to hormonal changes that affect the entire body, including the skin. Hormonal changes caused by the use of contraceptives and hormonal treatments will also affect the skin.

All these processes will lead to changes in the skin such as wrinkles, pigmentation alterations, sagging, and precancerous lesions like actinic keratoses, which, if left untreated, can develop into skin cancer. What you see in the mirror is just the tip of the iceberg, as subclinical lesions, not visible to the naked eye, may coexist with these, and it is important to treat them to prevent skin cancer. Therefore, before starting any anti-aging skin treatment, it is crucial to perform a thorough dermatological examination using a dermatoscope or skin microscope, Wood's lamp to determine the exact depth of pigmented lesions, and, if necessary, a skin biopsy of suspicious lesions.

With all this information, along with the personal medical history, an anti-aging skin treatment plan can be created, in which the most appropriate treatments for each case can be efficiently prescribed.
