I have a cluster of tiny white heads under lip. Why?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I have noticed a cluster of what looks like tiny whiteheads under my lip. After a couple of days of being there, I tried popping them, but they seemed to fill back with pus minutes later. Tired of them being there, I kept pushing on them until nothing but clear liquid was coming out.

Now the area is sore and scabbed. Does this sound like acne or cold sores? I have noticed more of the same clusters on both sides of my mouth now.

Kindly assist.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

If possible, forward a few pictures of the affected area of the lips to help you through.

Kind regards.

Patient's Query

Hello doctor,

Thank you for your reply.

The middle of the scab cracks and reopens every time I open my mouth too wide. The whole area is dried out from trying to dry the scabs and white heads with alcohol and peroxide.

Please advise.

Hello,

Welcome back to icliniq.com.

I reviewed the image you shared (attachment removed to protect patient identity).

Based on the appearance, I can see a crusted lesion just below the lower lip. Cold sores caused by herpes simplex virus (HSV) do not commonly occur in this exact location, making herpes less likely, although it cannot be completely ruled out without further evaluation.

The lesion appears more consistent with grade 2 acne vulgaris with secondary infection. Repeated squeezing, picking, and the use of alcohol or peroxide can further irritate the skin, delay healing, and increase the risk of scarring.

You may start applying Clindoxyl gel as prescribed by your doctor when new acne lesions appear. Avoid pricking or squeezing the lesions, as this can worsen inflammation and lead to permanent scars.

Although skin conditions such as parthenium allergy can occasionally affect the area around the mouth, they typically present with itching, redness, and eczema-like skin changes rather than pus-filled lesions like the ones you have described.

If you notice recurrent eruptions at the same site, especially if they are associated with burning, tingling, or grouped blisters, it would be reasonable to undergo HSV IgM and HSV IgG (types 1 and 2) testing. If HSV IgM is positive, treatment with antiviral medications such as Valacyclovir or Acyclovir may be considered under a doctor's supervision.

In the meantime, keep the area clean, avoid further irritation, and allow the lesion to heal naturally.

I hope this helps.

Thank you.
