Herpes simplex virus (HSV) is an infection that affects the vast majority of the world's population, remaining latent in nerve ganglia for a lifetime. HSV-1 typically causes lesions in the orolabial region (cold sores), while HSV-2 causes lesions in the genital area. Many procedures performed in aesthetic dermatology can trigger the reactivation of latent HSV, potentially leading to serious complications. In 2026, HSV prophylaxis prior to aesthetic procedures has become an integral part of patient safety protocols.
Aesthetic Procedures That Trigger HSV Reactivation
Nearly every aesthetic procedure that causes trauma, thermal injury, or inflammation to the skin can trigger the reactivation of HSV-1 lying latent in the trigeminal ganglion. High-risk procedures include:
- Laser treatments: Ablative laser (CO2, Erbium:YAG) skin resurfacing procedures rank among the highest-risk treatments. Fractional laser applications also carry a significant level of risk.
- Chemical peeling: Medium and deep chemical peels, particularly TCA and phenol peels, can trigger HSV reactivation.
- Dermal filler injections: Needle trauma and local tissue tension in lip filler procedures can predispose to orolabial herpes flare-ups.
- Microneedling and dermapen: Multiple micro-needle penetrations increase risk, especially in procedures applied around the perioral area.
- IPL (Intense Pulsed Light): IPL sessions applied to the facial area can act as a reactivation trigger.
Aesthetic Complications of HSV Reactivation
Herpes reactivation following an aesthetic procedure can follow a far more serious course than an ordinary cold sore outbreak. The main reasons for this are:
- Widespread disseminated infection: The virus can spread over large areas of skin with compromised barrier function after a procedure. Eczema herpeticum developing after laser treatment, in particular, can evolve into a painful, widespread infection covering the entire face.
- Scarring: An active herpes infection can disrupt the healing process, leading to permanent marks.
- Pigmentation disorders: Permanent hypo- or hyperpigmentation may develop at the site of infection.
- Treatment failure: The desired outcome from the aesthetic procedure may not be achieved due to herpes complications.
2026 Prophylaxis Protocols
Current guidelines mandate antiviral prophylaxis prior to certain aesthetic procedures in patients with a history of HSV or those who are seropositive.
Pre-Procedure Assessment
At every aesthetic consultation, the patient's HSV history should be thoroughly reviewed. Patients with frequent outbreaks each year, individuals using immunosuppressive medications, and those who have previously experienced herpes flare-ups following an aesthetic procedure should be considered high-risk.
Antiviral Prophylaxis Regimen
The standard prophylaxis regimen in current 2026 dermatology practice is as follows:
- Valacyclovir 500 mg: Started 1–2 days before the procedure, taken twice daily, and continued for 7–10 days after the procedure.
- Acyclovir 400 mg: An alternative regimen of three times daily for the same duration.
- For high-risk procedures: An increased dose of valacyclovir 1000 mg twice daily may be prescribed.
Prophylactic treatment suppresses viral replication before it begins, largely preventing clinical reactivation. While the rate of herpes reactivation following ablative laser in HSV carriers without prophylaxis can reach up to thirty percent, appropriate prophylaxis can reduce this rate to below one percent.
Procedure Day and Post-Procedure Follow-Up
- An aesthetic procedure is absolutely postponed in a patient with an active herpes lesion.
- After the procedure, the patient is informed about possible prodromal symptoms (tingling, burning, itching).
- In the event of suspicious symptom development, an immediate increase in antiviral treatment dose is recommended.
- The skin is closely evaluated at post-procedure follow-up appointments.
Patient Information and Informed Consent
During the informed consent process prior to an aesthetic procedure, the risk of HSV reactivation must be conveyed to the patient in a clear and understandable manner. The necessity of prophylactic treatment, possible complications, and the importance of treatment adherence should be emphasized.
