Children’s skin changes quickly.

A rash can appear after a hot afternoon, a new soap, an illness, a swimming lesson, or contact with something irritating. Many minor skin problems improve with gentle care and time. Others persist, repeatedly return, spread, interfere with sleep, or become difficult to identify without medical training.

Knowing when to schedule pediatric dermatology care can help families avoid months of trial and error.

Thomas Dermatology provides pediatric dermatology services for infants, children, and adolescents throughout Las Vegas, Henderson, and surrounding communities. Care may include the evaluation and treatment of eczema, acne, infections, warts, unusual moles, hair and nail changes, birthmarks, and less common childhood skin conditions.

Here is when a child may benefit from seeing a dermatology provider and what parents can expect from the appointment.

What Is Pediatric Dermatology?

Pediatric dermatology focuses on skin, hair, and nail conditions affecting babies, children, and teenagers.

Children do not always develop the same conditions as adults, and a condition may look or behave differently depending on the child’s age. Treatment also needs to account for a child’s skin sensitivity, growth, comfort, medical history, and ability to follow a care routine.

The American Academy of Dermatology explains that dermatologists diagnose and treat thousands of conditions affecting the skin, hair, and nails. Some dermatologists and dermatology teams receive additional training and experience in treating children.

Pediatric dermatology may be especially helpful when:

• A diagnosis remains unclear
• A rash does not improve
• Symptoms repeatedly return
• A condition affects sleep or daily activities
• Over-the-counter products have not helped
• The child is developing scars or pigment changes
• A skin problem is causing pain or emotional distress
• The treatment plan needs to be adjusted for the child’s age

A pediatrician can manage many common skin concerns. A dermatology provider offers more focused evaluation when the condition is persistent, unusual, severe, or difficult to treat.

Persistent Rashes and Childhood Eczema

Rashes are among the most common reasons parents seek dermatology care.

A short-lived rash may result from heat, friction, irritation, or a mild viral illness. A rash that lasts for weeks, repeatedly returns, becomes intensely itchy, or spreads despite home care may require closer evaluation.

One common cause is eczema, also called atopic dermatitis.

Eczema can cause:

• Dry or rough skin
• Red, brown, gray, or purple areas
• Intense itching
• Cracking
• Oozing or crusting
• Thickened skin after repeated scratching
• Sleep disruption

The appearance can vary according to the child’s age and skin tone. It may affect the cheeks and scalp in babies, the folds of the elbows and knees in older children, or the hands, eyelids, neck, and other areas.

Thomas Dermatology evaluates dermatitis and eczema in both children and adults. A dermatology visit can help determine whether the rash is eczema, allergic contact dermatitis, irritant dermatitis, psoriasis, a fungal infection, scabies, or another condition that requires a different treatment.

Parents should schedule an evaluation when itching repeatedly wakes a child, the skin cracks or bleeds, the rash continues to spread, or the family cannot identify what is triggering the symptoms.

Acne That Starts Early or Leaves Scars

Acne often begins during the preteen or teenage years, but it should not automatically be dismissed as something a child must simply outgrow.

Early treatment can help control breakouts and reduce the likelihood of permanent scarring or lingering dark marks.

A child or teenager may benefit from professional acne treatment when:

• Acne is painful or deep
• Cysts or nodules are developing
• Breakouts are leaving scars
• Over-the-counter products cause irritation
• Acne affects the chest or back
• The condition is affecting confidence
• Acne begins unusually early
• Breakouts persist despite consistent home care

A dermatology provider can determine the type and severity of the acne and create a treatment plan suited to the patient’s age, skin sensitivity, and lifestyle.

Teenagers also need realistic routines. A complicated regimen with several irritating products may be harder to follow and can sometimes worsen dryness and inflammation.

Thomas Dermatology’s article on why acne can continue into adulthood explains that acne is influenced by several factors and is not simply the result of unclean skin. The same principle applies to younger patients: acne is a medical skin condition, not a sign that a child is failing to wash properly.

Warts and Other Contagious Growths

Warts are caused by certain types of human papillomavirus and can spread through direct contact or shared surfaces.

Children commonly develop warts on the hands, fingers, feet, knees, and other areas prone to minor cuts or friction. Some disappear without treatment, while others multiply, become painful, or persist for a long time.

Professional treatment may be appropriate when a wart:

• Hurts when walking or playing sports
• Bleeds
• Is located near the face or genitals
• Continues to grow
• Spreads to other areas
• Has not responded to home treatment
• Cannot confidently be identified as a wart

Thomas Dermatology offers evaluation and treatment for warts. Parents can also read the practice’s guide, “My Warts Are Embarrassing. Can You Help?”, for an overview of commonly used treatment options.

Molluscum contagiosum is another viral skin condition frequently seen in children. It usually appears as small, smooth bumps and can spread through skin contact, scratching, towels, sports equipment, or shared surfaces.

Because warts, molluscum, skin tags, and other growths can resemble one another, an examination is useful before trying aggressive home removal methods.

Bacterial and Fungal Skin Infections

Children frequently come into close contact with other people through school, daycare, athletics, swimming, and shared equipment. That can make certain bacterial and fungal infections easier to spread.

Common examples include:

• Impetigo
• Ringworm
• Athlete’s foot
• Folliculitis
• Infected eczema
• Fungal scalp infections
• Nail infections

A dermatology evaluation may be needed when an area is rapidly spreading, painful, draining, repeatedly returning, or not improving with initial treatment.

Depending on the condition, a provider may diagnose it through examination or perform a scraping, culture, or other test. This matters because fungal, bacterial, inflammatory, and viral conditions may look similar but require very different treatments.

Using the wrong medication can delay improvement. For example, applying a topical steroid to an undiagnosed fungal infection may change its appearance and make it harder to recognize.

Moles, Birthmarks, and Unusual Growths

Most childhood moles and birthmarks are harmless. However, parents should bring attention to any spot that looks unusual, changes noticeably, repeatedly bleeds, becomes painful, or stands out from the child’s other moles.

Thomas Dermatology evaluates moles and pigmented lesions and can determine whether a spot should be monitored, photographed, tested, or removed.

Reasons to schedule an examination include:

• A mole is changing in size, shape, or color
• A spot repeatedly crusts or bleeds
• A growth is painful or persistently itchy
• A new lesion looks different from the child’s other spots
• A birthmark is growing rapidly
• A lesion interferes with vision, breathing, eating, or movement
• The child has a personal or family history that increases concern

Photographs taken in consistent lighting can help parents document visible changes between appointments.

Thomas Dermatology’s guide to when a mole may deserve closer attention provides additional information about changes patients should not ignore.

Hair and Nail Changes

Skin is only one part of dermatology. Dermatology providers also evaluate conditions involving the hair and nails.

Children may need evaluation for:

• Patchy hair loss
• Sudden shedding
• Scalp scaling
• Broken hairs
• Persistent dandruff-like symptoms
• Nail discoloration
• Thickened or distorted nails
• Repeated inflammation around a nail
• Suspected fungal infection

Patchy hair loss may have several possible causes, including alopecia areata, fungal infection, traction, habitual hair pulling, or inflammation.

A visual examination and, when appropriate, laboratory testing or a scalp sample can help identify the cause. Early evaluation is particularly important when hair loss is progressing or accompanied by pain, scaling, sores, or signs of infection.

Thomas Dermatology also provides care for nail fungus and other nail changes.

Vitiligo and Changes in Skin Color

Vitiligo causes areas of skin to lose pigment. It is not contagious and is not caused by poor hygiene.

The condition may begin during childhood and can affect any skin tone. On darker skin, the contrast may be especially noticeable.

A dermatology provider can distinguish vitiligo from fungal infections, post-inflammatory pigment changes, birthmarks, and other conditions that may create lighter areas.

Thomas Dermatology provides vitiligo evaluation and treatment. Treatment decisions may depend on the child’s age, the location and extent of pigment loss, how quickly it is changing, and how the condition affects the child.

Even when a skin condition does not cause physical discomfort, it can affect confidence, social participation, and emotional well-being. Those concerns are valid reasons to discuss treatment and support.

How the Las Vegas Climate Can Affect Children’s Skin

Las Vegas families regularly move between outdoor heat and heavily air-conditioned indoor spaces.

Low humidity, sun exposure, sweat, chlorine, frequent bathing, and sudden temperature changes can all affect a child’s skin barrier. These factors do not cause every skin condition, but they may aggravate dryness, eczema, heat rash, or irritation in children who are already susceptible.

Helpful habits may include:

• Using lukewarm rather than hot water
• Choosing gentle, fragrance-free cleansers
• Applying a thick fragrance-free moisturizer after bathing
• Rinsing chlorine or sweat from the skin
• Changing out of damp clothing
• Using broad-spectrum sunscreen appropriate for the child
• Choosing soft, breathable clothing
• Keeping fingernails short when scratching is a problem

Avoid introducing several new products at once. When a reaction occurs, changing one product at a time makes it easier to identify a possible trigger.

Families should also be cautious with essential oils, heavily fragranced “natural” products, harsh exfoliants, and adult acne products. Natural does not automatically mean non-irritating or appropriate for children.

When a Rash Needs Prompt or Emergency Care

Most childhood rashes do not require emergency treatment, but certain symptoms should not wait for a routine dermatology appointment.

Seek urgent medical guidance when a rash is accompanied by:

• Fever in a newborn or very young infant
• Rapidly spreading redness
• Severe pain
• Significant swelling
• Pus, drainage, or extensive yellow or honey-colored crusting
• Widespread blisters or peeling
• Purple or blood-colored spots that do not fade when pressed
• A child who appears unusually weak, confused, or seriously ill
• Eye, mouth, or genital involvement
• Dehydration or inability to drink

Call 911 for trouble breathing, swelling of the tongue or throat, fainting, or signs of a severe allergic reaction.

A dermatology office is appropriate for persistent or recurring conditions, but emergency symptoms require emergency care.

What to Expect at a Pediatric Dermatology Appointment

The first appointment normally begins with a medical history and a careful examination of the affected skin, hair, or nails.

The provider may ask:

• When the condition began
• How it has changed
• Whether it itches, hurts, or bleeds
• Which products or medications have been tried
• Whether anyone else in the household has symptoms
• Whether the child has allergies, asthma, or other conditions
• Whether there is a family history of skin disease
• What seems to improve or worsen the problem

Many conditions can be diagnosed through examination alone. In some cases, the provider may recommend a skin scraping, culture, patch testing, bloodwork, photography, or a small biopsy.

The treatment plan should be explained in practical terms, including how much medication to apply, where to use it, how often to use it, and what improvement or side effects the family should watch for.

How to Prepare for the Visit

Parents can make the appointment more productive by bringing:

• A list of current medications and supplements
• Photographs showing previous flares
• The names or photos of products used on the skin
• A timeline of symptoms
• Information about previous treatments
• Relevant allergy or medical history
• A list of questions
• Any insurance referral required by the plan

Do not intentionally stop a prescribed treatment before an appointment unless the prescribing provider tells you to do so.

When symptoms come and go, photographs can be particularly helpful. Take clear pictures in good lighting and include both close and wider views so the location and scale are visible.

When Should Parents Schedule an Appointment?

Consider scheduling pediatric dermatology care when:

• A rash lasts more than a few weeks
• Symptoms repeatedly return
• Itching disrupts sleep
• A child is developing scars
• The skin cracks, bleeds, or becomes infected
• Acne is painful or affecting confidence
• A mole or growth is changing
• Hair loss is progressing
• Nail changes do not improve
• The diagnosis remains uncertain
• The current treatment is not working
• A skin condition is interfering with school, sports, or daily life

Parents do not need to wait until a condition becomes severe. Earlier evaluation can often simplify treatment and reduce unnecessary product experimentation.

Frequently Asked Questions About Pediatric Dermatology

What ages can receive pediatric dermatology care?

Pediatric dermatology may include infants, children, preteens, and adolescents. The appropriate provider and treatment plan depend on the condition and the child’s age.

Does my child need a referral?

That depends on the family’s insurance plan. Some plans allow direct scheduling, while others require a referral from a pediatrician or primary care provider. Contact the insurer or Thomas Dermatology before the visit to confirm.

Can a dermatologist treat teenage acne?

Yes. Dermatology providers routinely evaluate teenage acne, including blackheads, inflammatory breakouts, cysts, scarring, and post-acne discoloration.

Can childhood eczema be cured?

There is currently no universal cure for atopic dermatitis, but treatment can reduce inflammation, itching, infections, and the frequency or severity of flares. Some children experience significant improvement as they grow older.

Are childhood warts contagious?

Yes. Warts can spread through direct contact or contaminated surfaces. Avoid picking or cutting them, and do not share tools used on the affected skin.

Should every mole on a child be checked?

Most childhood moles are harmless and do not require separate visits. A mole should be evaluated when it is changing, bleeding, painful, persistently itchy, or noticeably different from the child’s other moles.

Should food be removed from a child’s diet because of eczema?

Families should not begin broad elimination diets without guidance from the child’s pediatrician, allergist, or dermatology provider. Unnecessary dietary restriction can create nutritional risks and may not improve the skin.

Does Thomas Dermatology have offices outside Las Vegas?

Yes. In addition to its Las Vegas and Henderson offices, Thomas Dermatology has locations in Lake Havasu City, Kingman, and Bullhead City, Arizona.
