Aging changes on the skin are a group of common conditions and changes that occur with age.
Skin changes are the most visible signs of aging. Obvious signs of aging include wrinkles and sagging skin, white or gray hair.
Your skin plays a big role. It protects you in the environment and helps control your body temperature, fluids and electrolyte balance, as well as neurotransmitters that enable you to feel touch, pain, pressure. Include.
Although the skin has many layers, it can be generally divided into three main parts:
The outer part (epidermis) contains skin cells, pigments and proteins.
The middle part (dermis) includes blood vessels, nerves, hair follicles and sebaceous glands. The dermis provides nutrients to the epidermis.
The inner layer beneath the dermis (subcutaneous layer, hypodermis) contains sweat glands, some hair follicles, blood vessels, and fat. Each layer also contains connective tissue with collagen fibers for support and elastin fibers for flexibility and strength.
Skin changes are related to environmental, genetic and hereditary factors, nutrition, and other factors. The biggest factor is exposure to sunlight. This can be understood by comparing areas of the body that have been regularly exposed to sunlight with areas that have been exposed to sunlight.
Natural pigments seem to protect the skin from sun damage. People with blue eyes, and those with fair skin, are more prone to skin aging than people with dark skin and more pigmentation.
Skin changes and aging:
As you age, the outer layer of the skin (epidermis) becomes thinner, even if the number of cell layers remains unchanged.
The number of pigment cells that contain (melanocytes) decreases, but the size of the remaining melanocytes increases. As a result, aging appears to be thinner, paler and lighter (transparent) skin. Large colored spots (called age spots, liver spots, or freckles) may appear in areas exposed to sunlight.
Changes in connective tissue reduce the ability and elasticity of the skin. This phenomenon is called elasticity and occurs especially in areas exposed to sunlight. It gives leather-like skin elasticity, and a sunburned appearance to farmers, sailors, and people who spend a lot of time outdoors.
The blood vessels in the dermis become more fragile, leading to bruising, subcutaneous bleeding (often called aging purpura), cherry-like angioma (a gland made up of blood and lymph vessels), and similar conditions.
With age, the sebaceous glands produce less fat. In men, this reduction is less. In women, this decrease gradually increases after the onset of menopause, which leads to a decrease in skin moisture, resulting in dryness and pain.
The subcutaneous fat layer is thinner and reduces its natural and soft insulation layer. As a result, it increases the risk of skin damage and reduces the ability to maintain body temperature. Because the body has less natural insulation, it may suffer in cold weather
Hypothermia (low body temperature abnormalities).
Some drugs are absorbed by the fat layer, and the loss of this layer changes the function of these drugs.
Sweat glands also produce less sweat, which makes it harder to maintain a cool body, and puts a person at risk for overheating or stroke.
The growth of skin growths, warts, and other blemishes is more common in the elderly.
Effect of changes:
With age, you are more prone to skin damage. Your skin becomes thinner, more fragile, and the protective layer of subcutaneous fat is reduced. In addition, the skin’s ability to respond to touch, pressure, vibration, heat and cold may be reduced. Therefore, your skin is at higher risk for damage.
Rubbing or rubbing on the skin can damage the skin. Blood vessels are fragile and can be easily torn. Even after a minor injury, bruising, an accumulation of anemia under the skin (purpura), or an accumulation of blood (a hematoma) may occur.
This is often seen on the outer surface of the forearm, but can occur anywhere on the body. Skin changes and loss of subcutaneous fat, along with a tendency to be less active, as well as some nutritional deficiencies and other illnesses, contribute to more wounds and injuries.
Healing in older skin is slower than in younger skin. Wound healing may be up to 4 times slower, leading to deeper wounds and infection. Diabetes, vascular changes, decreased immunity, and similar factors also affect wound healing.
Common skin disorders:
Skin problems are very common in the elderly due to natural changes. More than 90% of older people suffer from some skin disorders.
Skin disorders can have many causes, including:
• Vascular diseases such as atherosclerosis
• Heart disease
• Liver disease
• Nutritional deficiencies
• Reaction to drugs
Other causes of skin changes:
• Allergies to plants and other substances
• Exposure to industrial and household chemicals
• Indoor heating
Sunlight can cause:
• Reduced flexibility (elasticity)
Non-cancerous skin cell mass (keratoacanthomas)
Pigment changes such as liver spots
• Thickening of the skin
Sun exposure is also directly linked to skin cancers, including basal cell carcinoma, squamous cell carcinoma, and melanoma.
Prevention is a lifelong process, as most skin changes are associated with sun exposure.
• Prevent sunburn
Use good quality sunscreen when you go out, even in winter.
• Wear protective clothing and a hat if necessary.
Good nutrition and adequate fluids are also helpful. Dehydration increases the risk of skin damage. Sometimes minor nutritional deficiencies can lead to skin lesions, and other skin changes, even if you have no other symptoms.
Moisturize your skin with lotions and other moisturizers. Do not use soaps that are highly fragrant. Bath oils are not recommended as they can cause you to slip and fall. Wet skin heals easier and faster.
