Before treatment

Cold sores before lip filler: what should you disclose?

Tell the practitioner before lip filler if you have recurrent cold sores. An injection around the lips may trigger a recurrence in some people, and treatment is postponed during an active cold sore or other infection.

01

Disclose your history

Mention previous or recurrent cold sores and any warning symptoms before the appointment.

Do not start, stop or change antiviral medication yourself. Any preventive plan requires an individual healthcare assessment.

02

When is treatment postponed?

Treatment is postponed if there is an active blister, broken skin, inflammation or infection near the lips.

If you are unsure about a lesion, contact the clinic before attending. A website cannot diagnose it.

03

What should you monitor afterwards?

Swelling, tenderness and small bruises can be normal injection reactions. Familiar tingling, burning and later blisters may suggest a cold-sore recurrence.

Contact BeautyBell if symptoms are unexpected. Increasing pain, visual symptoms or marked pale, grey or bluish skin requires urgent assessment.

Frequently asked questions

Can lip filler trigger a cold sore?

An injection around the lips may trigger a recurrence in some people with a previous herpes infection.

Can I have filler during an active cold sore?

No. Treatment is postponed until the lesion and other signs of infection have healed and timing has been reassessed.

Do I need preventive medication?

This is assessed individually. Do not start or change medication without healthcare advice.
