Aging Skin: What Changes as We Get Older—and How to Keep It Healthy

As we live longer, dermatologists are caring for an increasingly older population. The skin is often one of the first places where the effects of aging become visible—but aging skin is about much more than wrinkles and gray hair.

With age, the skin’s ability to retain moisture, repair itself, protect against environmental stressors, and regulate inflammation changes. These changes can contribute to dryness, itching, eczema, infections, skin fragility, and other dermatologic problems.

The good news? Many of the changes associated with aging skin can be managed, and a thoughtful skin-care routine can make a significant difference.

What happens to our skin as we age?

Several important changes occur naturally with aging:

• Less collagen and elastin, contributing to wrinkles, laxity, and loss of firmness

• Reduced sebum production, resulting in drier skin

• A thinner skin barrier, making the skin more susceptible to irritation and moisture loss

• Slower wound healing

• Changes in the immune system, which can affect inflammation and the skin's ability to respond to infections

• Cumulative UV damage, contributing to wrinkles, pigment changes, thinning skin, and skin cancers

• Hormonal changes, particularly around menopause, that can accelerate dryness and changes in skin thickness

  
  

Aging skin also becomes less resilient. Something that would cause little irritation in a younger person—such as frequent hot showers, harsh soap, or a dry indoor environment—can cause significant dryness and itching in an older adult.

The Skin Barrier Becomes Increasingly Important

The outermost layer of our skin acts as a protective barrier. It helps keep water inside the skin while keeping irritants, allergens, and microorganisms out. With aging, this barrier becomes less effective.

This can create a cycle:

Barrier dysfunction → dryness → itching → scratching → inflammation → further barrier damage

Chronic inflammation may also contribute to what researchers increasingly refer to as “inflammaging,” or the persistent, low-grade inflammation associated with aging.

Environmental factors such as UV radiation, pollution, and oxidative stress can further contribute to inflammation and damage to collagen and other components of the skin.

Simple ways to protect the skin barrier

For many older adults, basic skin care can be remarkably effective:

1. Moisturize regularly. Use a fragrance-free moisturizer, preferably shortly after bathing while the skin is still slightly damp.

2. Avoid overly hot showers. Hot water can strip oils from the skin and worsen dryness.

3. Choose gentle cleansers. A mild, fragrance-free cleanser is generally preferable to harsh soaps.

4. Consider ingredients that support the barrier. Moisturizers containing ingredients such as ceramides, glycerin, hyaluronic acid, or dimethicone can help improve hydration and barrier function.

5. Use sunscreen every day. UV exposure continues to damage aging skin and contributes to wrinkles, pigment changes, skin thinning, and skin cancer.

Itchy Skin Is Common in Older Adults

One of the most important—and sometimes overlooked—problems associated with aging skin is chronic itching. Dry skin, or xerosis, is extremely common in older adults. Itching can sometimes become severe enough to interfere with sleep and quality of life.

Importantly, itching doesn't always correspond to how dramatic the skin looks. An older patient with atopic dermatitis, for example, may experience significant itching with relatively little visible redness or rash.

Other causes of itching in older adults include:

• Eczema and atopic dermatitis

• Nummular dermatitis

• Prurigo nodularis

• Fungal or other infections

• Medication reactions

• Kidney disease

• Liver disease

• Thyroid disease

• Diabetes

• Neuropathy

• Iron deficiency

• Certain cancers

For persistent or unexplained itching, it is therefore important to look beyond the skin itself.

Don't Assume Every Rash Is "Just Aging"

Aging can change the way common skin diseases appear. For example, older adults with atopic dermatitis may have less of the classic red, inflamed rash seen in younger patients and may instead have prominent itching and eczema on the trunk or extremities.

Medication reactions can also mimic common inflammatory skin diseases. Drugs such as certain statins, diuretics, and anticholinergic medications may contribute to eczema-like eruptions or itching. This is one reason a careful medication review is an important part of evaluating an older dermatology patient.

Polypharmacy: When More Medications Can Mean More Skin Problems

Many older adults take medications prescribed by several different specialists. While these medications may each be appropriate individually, taking numerous medications—known as polypharmacy—can increase the risk of side effects, drug interactions, dizziness, falls, and medication-related skin problems.

For dermatology patients, medication review can be particularly important. This doesn't mean older adults cannot take effective dermatologic medications. Rather, treatment should be individualized, taking into account the patient's other medical conditions, medications, mobility, and ability to follow the treatment plan.

Aging Skin and Skin Cancer

Perhaps the most important reason to pay attention to aging skin is the cumulative effect of decades of sun exposure. As we age, we accumulate more UV damage, increasing our risk of:

• Basal cell carcinoma

• Squamous cell carcinoma

• Melanoma

• Precancerous actinic keratoses

• Sun-related pigmentation and texture changes

Older adults should continue regular sun protection and skin cancer surveillance. New, changing, bleeding, painful, or non-healing lesions deserve evaluation rather than being dismissed as "part of getting older."

Aging Well Starts With Healthy Skin

Aging is inevitable. Significant skin problems don't have to be. Aging skin benefits from a relatively simple foundation: Gentle cleansing + consistent moisturizing + daily sunscreen + appropriate medical evaluation

Beyond that foundation, dermatologists can help identify and treat eczema, chronic itching, skin cancers, precancerous lesions, infections, medication reactions, and other conditions that become more common with age.

Perhaps most importantly, caring for aging skin means recognizing that older adults are not simply younger patients with more birthdays. Their skin, immune system, medications, mobility, medical conditions, and treatment goals may all be different.

At our practice, we believe dermatologic care should be tailored to the whole patient—not just the skin condition in front of us.

When should you see a dermatologist?

Make an appointment if you develop:

• Persistent or severe itching

• A new or changing rash

• A sore that doesn't heal

• A new or changing mole or pigmented lesion

• Recurrent skin infections

• Unexplained bruising or skin fragility

• Severe or persistent dry skin

• A new rash after starting a medication

• Any lesion that bleeds, crusts, or repeatedly returns

  
  

Healthy skin is an important part of healthy aging. A good skin-care routine and regular dermatologic evaluation can help keep your skin comfortable, resilient, and protected throughout the years.
