Common questions
Perioral Dermatitis:Why did the steroid cream make it worse?
Steroids suppress inflammation quickly, so the rash fades within a day or two. They do nothing about what drives it, and when the cream stops the inflammation returns stronger, needing more steroid for less benefit. That is why the first step is always to stop.
Perioral Dermatitis:How long will it take to clear?
Longer than most people expect. The first one to two weeks off a steroid are usually worse, improvement becomes clear around weeks three to six, and full clearing commonly takes two to three months. Judging at two weeks means judging it at its worst.
Perioral Dermatitis:Is this acne?
No, though it is often treated as acne first. Acne produces blackheads and whiteheads, across the face, chest and back. Perioral dermatitis produces uniform grouped bumps around the mouth, nose or eyes, with a clear rim next to the lips, and it burns rather than itches.
Perioral Dermatitis:Do I really have to stop all my skincare?
For a few weeks, mostly yes. Heavy occlusive products are a main trigger, and layered actives keep the barrier damaged. A gentle cleanser, a light moisturizer if needed, and sunscreen is the whole routine while it clears. Products go back one at a time afterward.
Perioral Dermatitis:Will it come back?
Most people clear and stay clear. When it returns there is usually an identifiable reason - a steroid cream for something else, a new heavy moisturizer, or a long routine again. Knowing your trigger is most of the prevention.
Perioral Dermatitis:Should I stop my asthma inhaler?
No. Never stop a prescribed inhaler on your own. Rinsing your mouth and washing the skin around it after every dose cuts the residue reaching your face, and your dermatologist can talk to whoever manages your asthma if the inhaler is the driver.
Impetigo:How long is it contagious?
Until about 24 hours after antibiotics start, or until the sores have fully dried and crusted if untreated, which takes far longer. That is why treatment is offered even though it would clear on its own - it cuts the contagious period from a week or more to about a day.
Impetigo:When can my child go back to school or nursery?
Most settings ask for around 24 hours of antibiotic treatment first, with remaining sores covered. Rules vary between countries, schools and nurseries, so check the policy.
Impetigo:Will it leave a scar?
Ordinary impetigo almost never scars, because it sits in the top layer of skin. Flat pink, brown or pale marks fade over weeks to months, more slowly on deeper skin tones. Ecthyma, the deeper ulcerating form, does scar, and picking raises the risk in any form.
Impetigo:Why does my child keep getting it?
Usually eczema that is not fully controlled, which keeps supplying broken skin. Other reasons are scratching from bites or scabies, shared towels and bedding, or long-term Staphylococcus aureus in the nose. Look at those rather than repeat the antibiotic.
Impetigo:Can adults catch it from their child?
Yes, though it is much less common in adults with healthy skin. The risk rises with eczema, a cut, a graze or any other break. Separate towels, handwashing after applying the ointment, and hot washing of bedding reduce the chance.
Impetigo:Should I use a cream or tablets?
It depends how much skin is involved. A prescription ointment works as well as tablets for a few patches and avoids the side effects of oral antibiotics. Tablets or liquid are for widespread infection, rapid spread, large blisters, or an unwell child. Make that call with a doctor.
