Melasma on GLP-1: Prepare a Tinted-Sunscreen Plan

If facial patches concern you before or during GLP-1 treatment, ask whether they are melasma.

Check the rest of the protection

AAD also recommends broad-spectrum, water-resistant sunscreen, shade and a wide-brimmed hat. Apply sunscreen 15 minutes before going outside and reapply at least every two hours. [1]

Confirm what you are treating

A dermatologist can often identify melasma by examining the face and neck. AAD notes that other conditions can resemble it, so some people need a biopsy. Treatment may combine sun protection, prescription creams and sometimes a procedure. [2]

Bring your current sunscreen

Photograph the label and ingredient list before your appointment. Ask which product fits your skin tone and outdoor routine, and how to use it alongside any prescribed treatment. Write down where you will keep it for reapplication.
