What is skin aging?
Skin aging is portrayed by highlights, for example, wrinkling, loss of versatility, laxity, and a harsh appearance. This aging process is associated with phenotypic changes in the dermal cells as well as structural and functional changes in extracellular matrix components such as collagen and elastin.
What causes skin aging?
Several different factors have a direct effect on how quickly these signs appear on your body.
The poisons in tobacco smoke open your skin to oxidative pressure. This causes dryness, wrinkles, and other signs of skin aging.
Sun exposure and tanning
Tanning beds and sun exposure can penetrate your skin with UV rays. These rays damage the DNA in skin cells, which leads to wrinkles.
Some very rare genetic conditions can cause signs of skin aging in childhood and early adulthood. These conditions are called premature skin aging. Werner syndrome affects 1 in every million people. It causes skin wrinkles, grey hair, and baldness between 13 and 30 years old.
Hutchinson-Guilford syndrome is a rare condition, affecting 1 in 8 million children. Children with this syndrome do not grow as quickly as others in their age group. They also suffer from thin and bald limbs. The average life expectancy of children with Hutchinson-Guilford syndrome is 13 years.
Signs & symptoms of skin aging
There are three main signs of skin aging and each one affects facial skin differently:
- Fine lines and wrinkles are usually the first visible sign of skin aging.
- Sagging skin is a sign of a loss of volume.
- When our skin loses its elasticity, it becomes less firm, and deeper wrinkles form.
The main recognizable indications of skin aging are scarcely discernible differences and wrinkles. Small, shallow wrinkles known as laugh lines or crow’s feet tend to be noticeable at the outer corners of the eyes. These may appear around the age of thirty, but we are all aging and the way we age depends on our genes and our lifestyle. These fine lines are followed by wrinkles on the forehead. At first, these wrinkles possibly show up when our skin moves when we change our outward appearances and are known as unique wrinkles. As we age they become more prominent and develop into permanent wrinkles that can be seen even when our face is firm. Frowning can cause vertical lines between the eyebrows.
Loss of volume
The loss of volume and facial contours can be difficult to identify. The first signs of a loss of volume on the lips tend to be that the lipstick begins to bleed. The loss of face volume leads to sagging skin, flattening of the cheeks, and the “turkey neck”. Changes the general appearance of the face that can appear negative, sad, or tired. The fold that appears between the nose and the mouth, known as the nasolabial fold, is also associated with sagging skin and a loss of volume.
Loss of elasticity and deep wrinkles
As our skin matures, it weakens its structure and loses its elasticity and firmness. Skin becomes drier, appears more “crepe” and loses the radiance that we associate with youthful skin again, since our skin is individual like us, these changes become visible at different ages but the most common are those of people over 50 years of age.
Features of skin aging are diagnosed clinically. Suspected skin cancer lesions appear as growing lumps or sores that do not heal. Such lesions often undergo a diagnostic biopsy before or as part of treatment.
How do we treat skin aging?
Cancerous and precancerous lesions
- Actinic keratoses and intradermal squamous cell carcinomas (SCCs) are often removed with cryotherapy or treated topically.
- Basal cell carcinoma (BCC) is often removed by minor surgery. Superficial breast cancer can be treated topically or with cryotherapy.
- Cutaneous SCC and melanoma are almost always surgically removed.
Dry and discoloured skin
- Moisturizers help improve dry, flaky skin.
- Alpha hydroxy acids, vitamin C, lipoic acid, soy isoflavones, or retinoid creams that are used regularly over the long term reduce dehydration. It may also reduce the number of fine wrinkles and even pigmentation.
- Several other products are under investigation, but their benefits are unclear.
It includes procedures aimed at rejuvenating the optical skin:
- Fillers (for example, hyaluronic acid, polytetrafluoroethylene, and fatty grafts) to hide facial expression lines
- Botulinum toxin injections to reduce frown and reduce deep grooves
- Laser vascular therapy and sclerotherapy (injection of an inflammatory factor into the veins) to remove facial veins and hemangiomas
- Resurfacing procedures (for example, dermabrasion, chemical peeling, and laser peeling)
- Plastic surgery to remove excess sagging skin, including surgical or laser blepharoplasty for sagging eyelids, and pyeloplasty (facelift) to tighten jaws.
Intrinsic aging is inevitable. In premenopausal women, systemic hormone therapy may delay skin thinning. The skin is less dry with fewer wrinkles, and wound healing is faster than it was before the treatment. Hormone replacement is less effective in improving skin aging in the postmenopausal decades. The effects of topical estrogen, phytoestrogen, and progestin are under investigation.
Solar UV protection is essential for all ages. There are several steps you can take to reduce or avoid exposure to UV rays.
- Be aware of your daily UV index levels. In New Zealand, stick to the advice from Sun Protection Alert.
- Avoid outdoor activities in the middle of the day.
- Wear sun-protective clothing (such as a wide-brimmed hat, long sleeves, and pants or skirts).
- Apply a high sun protection factor (SPF> 30), broad-spectrum sunscreen to exposed skin.
- Try not to smoke and, where conceivable, dodge introduction to contaminations.
- Get plenty of exercises: Active people look younger than inactive people.
- Eat fruits and vegetables daily.
Several oral supplements that contain antioxidant and anti-inflammatory properties have been advocated for delaying skin aging and improving skin health. These include carotenoids, Polyphenols, chlorophyll; Aloe Vera vitamins B, C, and E, Red ginseng, Squalene, And omega-3 fatty acids. Their role in fighting skin aging is unclear.
