Oil glands in the skin secrete oil which open into oil ducts in the skin. The opening of the oil ducts on the skin surface accounts for the pores. Sometimes it gets blocked and infected.
Hence, the activity of the oil glands and the elasticity of the skin is the reason for the pores we see on the skin. So if you want to combat the pores on the skin, we will need to know what causes your problem.
1)If you have history of bad acne, oily skin etc then laser and chemical peels targeting hyperactive oil glands will help. Laser(nonablative, subablative, ablative) and peels do help with pores but its not permanent. You still need a healthy lifestyle, good daily skincare regime and skin rejuvenation therapy.
2)If your pores are due to the poor elasticity of skin, due to genes, lifestyle eg smoking, poor daily skincare regime. Then treatment like micro-botox, skin boosters, RF treatment helps better. Yes, and of course healthy lifestyle and daily skincare regime.
Hope this helps!
