Detailed answer

Yes, you can use sunscreen on your lip filler serum gel tube. Sunscreen helps protect your skin from harmful UV rays, which can cause damage and premature aging. However, it is important to ensure that the sunscreen you use is suitable for application on the lips. Look for a lip balm or lip sunscreen that is specifically formulated for the delicate skin of the lips. Apply it generously and reapply as needed throughout the day, especially when exposed to the sun.
