I see that you are having dark spots on your face after getting a sunburn. This is called hyperpigmentation. It happens when your skin makes more pigment, called melanin, to protect itself from the sun. To help, avoid direct sunlight, use sunscreen, wear a hat, and apply aloe vera to soothe the burn. Over time, the dark spots may fade, but protecting your skin from the sun is key.
