whats wrong that you want to close them up for? are they too big or causing too much oil and pimples? i would suggest ( works for me ) opening them up daily and closing them simply by 1) use facecloth and wet it with cold (not super cold but just right) and puttting the rag onto your face
. leave there for about two minutes this opens the pores 2) to close them do the same but use a warm cloth instead. or you can pour some hot water into a bowl and put your head
Actually, steam and hot water is used to open pores, as most facialists and aestheticians do this during their treatments. Rinsing with cold water will close them and reduce the appearance of the pores. But, sorry, there is not treatment to permanently close your pores - its a way for your skin to "breathe."
pores is commonly associated with excessive oiliness and acne. The excessive oiliness of the skin is in turn triggered by the hormonal changes in the body.
Large pores can be easily dealt with proper cleansing and frequent toning and moisturizing of the skin. Other treatments to consider include microdermabrasion, skin resurfacing lasers and chemical skin peels.
In my opinion you should discuss these treatment options with a cosmetologist/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.
