Pores are the openings for our hair follicles. They also contain our sebaceous (oil) glands. As we age, they tend to become enlarged. Having rosacea can add to this. The truth is, that they are very hard to treat and make smaller. Having said that, I do believe that multiple fraxel treatments (Fraxel Restore, 1550nm wavelength) can be helpful. For my patients, I put them on Retin-A (Tretinoin) which can help to shrink the oil glands and decrease pore size and I offer resurfacing - either the Fraxel laser, or the Lumenis Deep FX CO2 laser.
Fraxel is an amazing laser and works best on pigmentation, sun damage, acne scars, and overall facial rejuvenation. Some patients have diminished pore size. I have found the Ematrix Laser is an excellent way of minimizing pore size. It is important to find a board certified dermatologist with a great deal of experience in lasers and cosmetics for the best results.
