From your description it could either be a reaction to some new cream that you used or could be some hormonal imbalance or something that you ate and you are allergic to. Vitamin C capsules can also cause sudden acne breakouts in some people. Start using a regular face wash for acne-prone skin and appropriate moisturiser and sunscreen according to your skin type after consulting with a dermatologist. Also exact diagnosis and treatment could be ex exited only after examining your face.So kindly meet the dermatologist close to you and consult for the same .if its acne it has to be treated promptly coz acne can cause bad scars which are later difficult to treat whereas acne can be treated easily. Thankyou and Regards.
