Pimples or acne on face generally occur after you get exposed to the sun for longer duration. It is sometimes called as photo-sensitivity and requires quick medical attention.

When you go outside in sunlight without covering your face, the UVA and the UVB rays penetrate deep within the skin layers of the face.
This makes the sebaceous glands present beneath the skin more active and they start secreting more sebum (a type of oil), the presence of excess oil gives an environment for the bacteria to flourish, they grow and reproduce and cause pimples.
