Red dots on the face can be caused by allergic dermatitis due to allergic factors, or one possibility is acne. Because acne also manifests itself as a kind of red dot, especially in the case of acne vulgaris or acne papulosa, the red dots appear with a certain degree of intensity. If there is also a pustular reaction, acne may be accompanied by some infection. Other types of skin diseases, such as infectious diseases and fungal infections called furunculosis folliculitis, may also be present.
