Hello,
Since you are having such bumps and red and flushed cheeks, it can be due to whiteheads, comedones or rosacea. Whitehead is a yellowish or blackish bump or plug on the skin and is a type of acne vulgaris. It is caused by excess oils that have accumulated in the sebaceous gland's duct.
Cleanse the area thoroughly and apply a good mild exfoliating scrub on that. For whiteheads, creams containing resorcinol, salicylic acid or benzoyl peroxide are used but they should be taken after a dermatologist’s guidance.
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.
