The dark marks and pimples may be a result of the increased oil secretion over the face or if you have applied any steroid-containing creams over the dark patches, it may have caused the pimples as well.
Next Steps
Please consult a dermatologist near you and seek immediate treatment.
Health Tips
Kindly do not self-medicate or use any over-the-counter creams.
Sun protection is very important to prevent further dark patches, both in the form of sunscreen as well as physical protection from sunlight (umbrellas, hats and cloth)
