Background:
Actinic keratoses (AKs), also known as solar keratoses, are precancerous skin lesions that typically occur following long-term exposure to ultraviolet radiation. AKs can evolve into cutaneous squamous cell carcinoma (SCC) if left untreated. Treatments for AKs typically cause temporary, irritable erythematous skin barrier disruption.

Objective:
The objective of this article is to provide recommendations for the pre-treatment and post-treatment care for AKs in order to improve patient outcomes, particularly in the Australian and New Zealand setting.

Discussion:
Many of the treatments for AKs have associated side effects that might affect skin barrier function. Post-treatment care is required to aid skin repair and to protect the skin. Patients should be instructed on how to care for the skin during the healing process using a gentle skin cleanser and a moisturiser. Routine sun protection measures all year round reduce recurrence and progression of AKs.
