Pediatric Dermatology

Pediatric Patients in Exton, PA

At Liu Dermatology, we believe that children deserve the utmost patience, compassion, and empathy when it comes to medical care. We strive to create a warm, caring, and child-friendly environment to put even the most anxious little ones at ease. For very young children, less is often more, especially when it comes to procedures. However, in situations where a procedure is necessary, we will do everything we can to make it as smooth and comfortable as possible. We aim to build trusting relationships with our pediatric patients that boost their confidence and prepare them well for future medical encounters.

Common pediatric skin conditions we evaluate and treat:


Atopic dermatitis (eczema) is a condition that causes dry, itchy, and inflamed skin. It's common in young children but can occur at any age. Atopic dermatitis can be long-lasting (chronic) and tends to flare at certain times. It can be irritating but it's not contagious.


Molluscum contagiosum is a common skin condition that typically affects children. It is due to a virus in the skin but it's not dangerous. Molluscum will often go away on its own but it may take several weeks to months. The most effective treatments for molluscum are in-office procedures.


Warts are common and harmless skin growths that are caused by a virus. Many children will get warts on various parts of their body, and although they can sometimes go away on their own, it may take several months. Liu Dermatology offers a variety of wart treatments for pediatric patients.


If your child has a birthmark, you’ll likely see a spot, patch, or lump that looks different from the rest of your child’s skin. You may see this when your baby is born. Some birthmarks appear shortly after birth. Birthmarks come in many shapes and colors. You may see a flat or raised mark. It may be the size of a pinhead or cover a large area of your child’s skin. Most birthmarks fall somewhere in between. A birthmark can be pink, red, tan, brown, or any other color. Some look like a bruise. Others look like a stain on the skin. Some birthmarks are common. It’s estimated that between 3% and 10% of babies are born with a type of birthmark called a hemangioma. Other birthmarks, such as port wine stains, are less common.


Acne is a common skin condition that occurs when hair follicles or pores are clogged with oil and dead skin cells, resulting in whiteheads, blackheads, or pimples varying in size and severity. Acne can occur anywhere on the body (face, neck, back, shoulders, etc) and affects people of all ages, though this condition is more prevalent among teenagers and young adults. There are many types of effective treatments for acne, which are prescribed based on the patient’s unique profile and specific symptoms.

Liu Dermatology is also proud to be one of the only practices in Pennsylvania using the AviClear device. AviClear’s 1726 nm wavelength treats acne at the source by selectively targeting and suppressing the sebaceous gland safely and effectively. Designed with patient comfort in mind, AviClear is enhanced with AviCoolTM contact cooling for an optimal and safe treatment experience.

Dandruff (cradle cap)

Also called seborrheic dermatitis, dandruff can affect children of all ages. Sometimes it causes itching and flaking in the scalp, and in severe cases, may even cause hair loss.

Disorders of Pigmentation

Skin color is determined by a pigment known as melanin that is made by specialized cells in the skin, called melanocytes. The amount and type of melanin determine a person's skin color. Skin pigment disorders affect the amount of melanin in a child's skin, and thus affect skin color.

All children under the age of 18 must be accompanied by a parent or other adult guardian at their appointments.
