Hello,
It can be due to irritated hair follicles after facial or clogged pores. Avoid using any lotions and creams over the face for the meantime. Wash your face with a mild cleanser with moisturizing properties like Cetaphil. Pat your face dry. Then apply a good hypoallergenic moisturizer over the area and see if this improves. If the symptoms still persist then you can apply mild steroid.
If the irritation persists then please get it evaluated from a dermatologist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
There's two possible reasons, the aesthetician failed to properly cleanse away the various products used, thus clogging the pores leading to the bumps, or, the aesthetician use a product that wasn't right for your skin type. Either way, use a gentle cleanser, non-alcoholic toner, and light non-comdegenic moisturizer and make-up. You'll see relief in about a week's time. Good luck!!
