or facial 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.
Hope it helps. Take care and pls do keep me posted on how your boyfriend is doing or if you have any additional queries.
