Hello,
Without examination, confirmation of a diagnosis is tough, but it sounds like milia.They are white pimples that occur mostly on the upper cheeks, nose and chin. The best way to prevent milia is to avoid treating the skin with excessively harsh chemicals and to limit sun exposure. Also use good quality cosmetics and exfoliate the skin regularly. If still the symptoms persist then chemical peeling or laser removal can be done. Please consult a dermatologist in that case.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
