چکیده
Skin aging is a natural process, which consists in reducing the biological activity of body’s cells, slowing down regenerative processes and loss of adaptability. The decisive role is played by genetic factors and associated with them external factors, such as: UV radiation, environmental pollution, smoking, improper care and internal factors connected with hormonal regulation disorders, poor nutrition and vitamin deficiencies. We can distinguish endogenous and exogenous skin aging. Some of these changes can be eliminated and prevented, but unfortunately together with the passage of time, there are distinctive symptoms of aging, such as: an excess of the skin on upper eyelids, “crow’s feet” in side corners of the eye, clearly marked nasolabial folds, transverse forehead creases and frown lines, prolapse of the nose’s tip, less clearly marked line of the mandible, neck wrinkles, visible horizontal bands of platysma, prolapse of side parts of cheeks, thinning of the skin and subcutaneous tissue atrophy contributing to clear wrinkles and skin laxity and much more. Substances, which effectively prevent aging of the skin, include: vitamin A and its derivatives, UVA and UVB protective filters, hydroxyl acids (especially glycolic acid, because of its smallest molecule), antioxidants, hormone-substances and hyaluronic acid. Non-invasive (non-surgical) rejuvenating programs include: superficial chemical peelings, local retinoids, botulinum toxin, filling, volumetry, threads, mesotherapy, rollcit, microdermabrasion, lasers and much more.
