Skin Aging: Triggers
Over time the state of skin deteriorates significantly. Skin loses its elasticity and firmness, develops wrinkles, and may become dry and flabby. There are a number of factors causing skin aging, which can be divided into two major groups:
- internal (genetic, biological);
- external (environmental, mechanical, etc.).
Biological skin aging occurs on the background of the natural (and often genetically predetermined) age-related changes in the human body. Internal factors provoking these changes include:
- ormonal disruptions;
- thickening of the horny layer of the skin and thinning of the layer of functionally active cells of the epidermis;
- deceleration of regenerative processes (in young age, full recovery of epidermal cells takes 28-30 days, in old age it takes about 55-60 days);
- gradual degradation of yellow and collagen fibers;
- abnormality of the processes responsible for the skin’s natural hydration;
- slowed production of hyaluronic acid, etc.
External causes of aging skin are changes that occur depending on lifestyle, health, nutrition, environmental conditions, type of human activity, and other external circumstances. They are the following:
- presence of systemic or dermatological diseases
- prolonged exposure to the sun
- negative effects of free radicals
- smoking and alcohol
- inappropriate use of cosmetics (e.g., using lifting creams in the absence of appropriate indications and so on.)
- poor environment and unfavorable weather conditions (frost, drought, etc.)
- incorrectly done cosmetic procedures
- frequent stress
- lack of sleep
Fortunately, modern cosmetology has a wide range of techniques that help to slow down skin aging and eliminate age-related changes. One of the most successful skin treatments for aging is the use of medicines and cosmetic products that have anti-aging properties.
Special Features Of Anti-Aging Products
Unfortunately, not all anti-aging products and their ingredients have properties that are equally effective and safe. Some of them do work and rejuvenate and beautify the skin, while others cause significant harm to the body.
Effective And Safe Anti-Aging Products
- Retinols (vitamin A and its derivatives) are perhaps the most common components of creams, masks and other anti-aging cosmetics. It is proven that compounds belonging to this group stimulate collagen production, accelerate regeneration of the epithelial layer, have antioxidant properties and smooth small wrinkles (like fillers).
- Peptides – a group of substances that have molecules consisting of several amino acid residues connected in a chain by peptide bonds. According to experts, substances belonging to this group can restore blood micro circulation, improve skin elasticity, stimulate synthesis of elastin and collagen, smooth out expression lines and age-related wrinkles, stimulate regeneration processes, control melanin production and help to establish work of the natural mechanisms of antioxidant defense.
- Antioxidants – substances able to inhibit oxidative processes in the body. The main function of compounds belonging to this group is to neutralize harmful effects of free radicals. They allow skin to become more elastic and radiant, and give skin good tone and healthy color.
- Estrogens – a type of hormone. Substances containing estrogen prevent early skin aging and formation of mimic and age-related wrinkles. Estrogen allows for regeneration of epithelial tissue to be accelerated, and gives skin the ability to maintain long-term elasticity and firmness.
Harmful Properties Of Anti-Aging Products
Most cosmetic products, regardless of their price category and country of origin, contain components that can harm your body as well. The most common of these are sulfates and oil products.
Sulfates are synthetic substances (salts of sulfuric acid) used in the cosmetic industry as lathering and cleaning components. Nowadays, compounds belonging to this group can be found in most hygiene and cosmetic products. Experienced dermatologists claim that regular use of products that contain sulfates can result in skin thinning and acceleration of skin aging, as well as increase skin’s vulnerability to damages and its tendency to develop allergic reactions.
Formulations based on oil (mineral oil, propylene glycol, polyethylene glycol, petroleum butter, etc.) are used in the cosmetic industry in products that prevent skin dehydration. However, studies have shown that compounds belonging to this class can form a thin layer on the surface of the skin that prevents toxins, metabolic products of the human body and other harmful substances from exiting through the skin pores. Thus, long-term use of cosmetics that contain oils can cause premature aging of the skin, appearance of wrinkles, acne and rashes.
Improperly selected products for aging skin treatments often cannot bring an expected result, but even adversely affect condition and appearance of the skin. That is why anti-aging cosmetics and care products should be selected with caution.
