Sebaceous glands produce less sebum, so the protection against infection afforded by the acidity of sebum is reduced. This makes the skin less able to resist disease and skin infections, which is why older people have an increased susceptibility to skin infections.Nov 27, 2017
As we age, our skin changes in ways that can make it more prone to disease. That’s because older skin is less oily, less elastic, and thinner. It bruises easily and can take a long time to heal when cut.
With aging, the outer skin layer (epidermis) thins, even though the number of cell layers remains unchanged. The number of pigment-containing cells (melanocytes) decreases. The remaining melanocytes increase in size. Aging skin looks thinner, paler, and clear (translucent).
Most boils are caused by Staphylococcus aureus, a type of bacterium commonly found on the skin and inside the nose. A bump forms as pus collects under the skin. Boils sometimes develop at sites where the skin has been broken by a small injury or an insect bite, which gives the bacteria easy entry.
How do the skin’s accessory structures change over time? Over time less sebum is produced (drying of skin and hair), hair growth slows and whitens, nails harden, sensitivity to pain and pressure diminishes, and the ability to control body temperature falters.
Reduced functional capacity and increased susceptibility of the skin with development of dermatoses such as dry skin, itching, ulcers, dyspigmentation, wrinkles, fungal infections, as well as benign and malignant tumors are the most common skin conditions in aged populations worldwide.
Skin changes that accompany aging include: Roughened or dry skin. Benign growths such as seborrheic keratoses and cherry angiomas. Loose facial skin, especially around the eyes, cheeks, and jowls (jawline)
Fragile or thin skin that tears easily is a common problem in older adults. Aging, sun exposure and genetics all play a role in thinning skin. Certain medications, such as long-term use of oral or topical corticosteroids, also can weaken the skin and blood vessels in the skin.
What are the signs of premature aging?
Exposure to sunlight is the single biggest culprit in aging skin. Over time, the sun’s ultraviolet (UV) light damages certain fibers in the skin called elastin. The breakdown of elastin fibers causes the skin to sag, stretch, and lose its ability to snap back after stretching.
Opportunistic fungal infections have increased, because older patients are now receiving transplanted solid organs or bone marrow, undergoing aggressive treatment of malignancies, and taking immunosuppressive medications for dermatologic and rheumatologic diseases.
No direct connection exists between mineral or vitamin deficiency and the formation of boils; however, having an adequate supply of vitamins and minerals does keep your vital body functions in general good working order, promoting a stronger immune system to fight bacterial infections.
Pruritus in elderly can be defined as idiopathic chronic pruritus in a person over 65 years old. Pruritus may present with or without skin lesions. In previous reports, the prevalence of pruritus in elderly patients was 11–78% [1,2,3].
Under the epidermis, firmly stuck to it, lies the middle layer of skin (the dermis). It is made up of a dense network of tough, elastic collagen fibers. … In places, the dermis bulges into the connective tissue that surrounds our muscles and bones and connects them with the skin.
Skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. … When body temperature falls, the sweat glands constrict and sweat production decreases.
Here are a few tips for caring for maturing skin:
Elderly Skin Care Tips
Aging skin is thought to be the most common cause of senile purpura. As the body ages, the skin becomes thinner and more delicate. Over time, exposure to ultraviolet (UV) rays weakens the connective tissues that hold the blood vessels in their place.
Age Related Dysfunctions to the Integumentary System
The most common causes of ulceration are venous and arterial disease. Diabetes mellitus, pressure, vasculitis, metabolic abnormalities and skin cancer are all unusual causes of leg ulceration, but must be considered in the differential diagnosis.
You produce less collagen and elastin — the fibers that help your skin look supple and smooth — the older you get. Pollution, stress, and smoking cigarettes all take a toll on skin over your lifetime and can contribute to visible signs of aging. As you age, your skin produces less oil than it did when you were younger.
This is caused by thinning of the epidermis (surface layer of the skin). Skin becomes more fragile as we age. Increased skin fragility is caused by flattening of the area where the epidermis and dermis (layer of skin under the epidermis) come together.
Crepey skin is thin and looks finely wrinkled like crepe paper. It may also sag or feel loose. While crepey skin is similar to common wrinkles in many ways, the condition tends to impact larger areas, and this skin feels noticeably more fragile and thin.
The seven signs of ageing
FOR most of their lives both men and women’s faces age at the same rate – that is, until women hit 50.
From around the age of 25 the first signs of aging start to become apparent on the surface of the skin. Fine lines appear first and wrinkles, a loss of volume and a loss of elasticity become noticeable over time. Our skin ages for a variety of different reasons.
Here’s how to slow aging:
This 2014 study confirms that caffeine slows down your wound healing process and accelerates aging of your skin. Researchers found that exposure to caffeine reduces newly synthesized collagen in your skin cells. To put it simply, the more caffeine you consume, the more your skin ages.

The elderly population, which is increasing worldwide, is particularly vulnerable to Candida infections. This can be due to several factors such as high frequency of comorbidities, aging-related physiological changes, polypharmacy, and high colonization rate [9–13].
Fungal infections are more likely in people with weak immune systems. This includes people with illnesses such as HIV/AIDS, and people taking medicines such as steroids or cancer treatments. People with diabetes also tend to develop fungal infections. Very young and very old people, also, are groups at risk.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fluconazole in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require an adjustment in the dose for patients receiving fluconazole.
Risk factors for boils
Poor hygiene – sweat and dead skin cells in natural creases and crevices, such as the armpit, provide a hospitable home for bacteria. Nutrition – inadequate nutrition may reduce a person’s natural immunity. Broken skin – other skin conditions, such as eczema, can break the skin surface.
