I cannot confirm anything without examination but it can be ectopic sebaceous glands, blocked glands or due to excess production of keratin. Exfoliation, intensive moisturizing creams, creams and lotions containing alpha hydroxy acids and urea may be used to temporarily improve the appearance and texture of affected skin.
If the symptoms persist then please get an evaluation done 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.
Thank you for your thoughts on this. Will follow your advice and post back here.
