Impetigo

Q My child gets impetigo 2 to 3 times a year. Can Korean medicine really reduce reinfection?

A. Repeated infection is a problem of a weak skin-immunity foundation. Clearing it with antibiotics each time is important too, but strengthening the spleen-stomach function and building up the vital qi (jeong-gi) provides genuine help in reducing the frequency of reinfection in the same environment.

Q My child has atopic dermatitis and keeps getting impetigo from scratching. Can both be managed together?

A. When the skin barrier is weak from atopic dermatitis and scratch wounds are frequent, impetigo recurs easily. Both conditions share a common background of dry, immunity-weakened skin, so stabilizing the atopic dermatitis while strengthening skin immunity often reduces impetigo recurrence as well.

Q Impetigo keeps appearing around the nose — is it related to rhinitis?

A. When you frequently wipe or touch around the nose due to rhinitis, the mucosa and skin become damaged, making it easy for bacteria to enter. Managing the rhinitis together to reduce irritation around the nose also lowers the frequency of impetigo recurrence.

Q How should I care for impetigo at home during treatment? I'm not sure how to handle bathing or wound care.

A. Do not touch the affected area with your hands, and if needed, wash it gently with a mild soap. Do not forcibly pick off the crusts, and use disposable gloves or a cotton swab when applying ointment to prevent self-infection. Keep towels and bedding separate for personal use.

Q I'm a parent in Dongincheon, and my child has impetigo. When can they return to daycare or school?

A. Once 24 to 48 hours have passed since starting antibiotic treatment, no new lesions are appearing, and the crusts begin to dry, your child can resume attending. Until the crusts have completely fallen off, it is recommended to cover the affected area with a dressing or long clothing when sending them.

Q I'm applying an antibiotic ointment at home — what symptoms mean I should go to the ER or hospital right away?

A. If high fever appears, the lesions spread rapidly with the surrounding skin red and swollen (cellulitis), severe pain, facial swelling, or urine that is reddish or reduced in volume, you must go to the hospital immediately. This is a stage that is difficult to manage at home with ointment.

Q My baby has just turned one — is it safe to use herbal medicine? I'm worried about giving herbal medicine to such a young child.

A. Herbal medicine is prescribed with the dose adjusted to age and weight, and it is composed specifically for children so it can be used safely. If you tell us the child's age, weight, and any medications currently being taken during the visit, we will prescribe accordingly.

Q The pediatrician prescribed both an antibiotic ointment and oral antibiotics — is it okay to use herbal medicine alongside them?

A. Topical antibiotic ointments act only on the skin, so they can be used at the same time as herbal medicine without any problem. For oral antibiotics and herbal medicine, simply leave an interval of about 1 to 2 hours between them. If you tell us during your visit which medications you are currently using, we will adjust the herbal medicine accordingly.

Q Once impetigo treatment starts, how long does it usually take for the crusts to fall off and the skin to heal?

A. With topical antibiotics, noticeable improvement often begins within 2 to 3 days, and the crusts frequently subside within 5 to 7 days. Even when oral antibiotics are needed, it usually clears within 7 to 10 days. However, if it spreads quickly or deepens, it may take longer.

Q I heard impetigo can cause kidney complications — should I keep monitoring even after full recovery?

A. Rarely, glomerulonephritis (kidney inflammation) can develop after streptococcal impetigo, so if swelling, blood in the urine, or decreased urination appears within 1 to 3 weeks after recovery, you should go to the hospital immediately. With proper treatment, most recover without complications, and taking antibiotics lowers this risk.

Q Why does impetigo develop? My child has honey-colored crusts on the skin — is it an infection?

A. Impetigo is an infectious skin disease caused by bacteria such as Staphylococcus aureus or streptococcus invading the skin. The most common form begins at a small wound, a mosquito bite, or the mucosa around the nose and forms honey-colored (golden) crusts. It is especially common in children and is highly contagious.

Q I heard there are several types of impetigo — how do they differ?

A. It is divided into three types: non-bullous (honey-colored crusts, most common), bullous (large blisters plus thin crusts), and ecthyma (deeper ulcers). Severity and treatment intensity differ by type, so distinguishing them is important.

Q Are there foods to avoid when you have impetigo? My child loves sweets — is that okay?

A. Foods high in sugar such as sugar, snacks, and sweet drinks, as well as greasy foods, increase internal heat and dampness and slow recovery from bacterial infection. During recovery, a light diet centered on vegetables and fruit with plenty of moisture helps speed healing.

Q I'm a parent in Dong-gu, Incheon, and I'm worried my older child's impetigo will spread to the younger one. In what situations does it spread most easily?

A. Direct skin contact and sharing towels, bedding, or clothing are the highest risks. Scratch wounds and mosquito bites are also routes through which bacteria easily enter. Self-infection can also occur if you touch the affected area and then touch elsewhere.

Q I'm looking for somewhere near Dong-gu, Incheon to care for my child's skin. How does the first visit proceed?

A. At the first visit, we check when and where the lesions appeared, what medications are currently being used, and whether any family members have similar symptoms. We examine the skin and the child's overall immune and digestive condition to set a Korean medicine treatment plan and lifestyle management direction together.

Q What is the specific sequence of steps involved in treating impetigo with Korean medicine?

A. The treatment proceeds in three stages: first, clearing heat and detoxifying to expel heat toxins and eliminate the root cause of bacterial infection; next, strengthening spleen and stomach functions to restore immunity; and finally, reinforcing vital energy (正氣) to prevent reinfection.

Q What should I prepare before a Korean medicine clinic consultation to help the visit?

A. If you organize the time the lesions appeared, their location and form (crusts, blisters, or ulcers), the name of the antibiotic currently being used, and whether any family members have similar symptoms, the visit will be faster and more accurate. If possible, taking photos of the lesions to bring along is even better.

Q I heard antibiotics cure it quickly — is there really any need to combine Korean medicine treatment as well?

A. Antibiotics are central to quickly clearing the bacteria, while concurrent Korean medicine treatment serves to build the immune foundation that prevents reinfection. If you reinfect frequently or your skin remains weak even after recovery, Korean medicine treatment that reinforces immunity and vital qi can be genuinely helpful in preventing recurrence.
