First of all, pore size is related to oil production, and although this is affected by other factors, it is primarily determined by one’s genetics. Individuals who are genetically “programmed” to produce more oil will naturally have a larger pore size. Therefore, having larger pores does not necessarily mean that the pores are “enlarged.” However, pores may become even larger over time if they have been stretched by prolonged congestion with oil and debris. For this reason, it is important for persons with oilier skin to utilize products such as salicylic acid and retinoic acid that will control oil buildup in the pores, as well as received regular professional treatments that involve extraction of the pores.
Having said that, IPL treatments are actually not effective treatment for reducing enlarged pores. The best way to treat enlarged pores once is to remove the upper layers of the skin while also stimulating deeper cellular renewal. IPL treatments do not have much of an effect on the more superficial layers of skin as it does not remove skin tissue. It does have some benefit in terms of collagen stimulation, and therefore could have some effect on pore size, but it would definitely not be the treatment of choice for this condition. Both chemical and laser resurfacing can provide this benefit. If a patient who presents enlarged pores is still experiencing oily skin, I will generally recommend chemical peels. This is especially true for a patient with an acneic condition. This is because chemical peels will offer the added benefit of balancing oil and controlling acne conditions. In this way, we are treating both the symptom and the cause. I may use a series of six or more SkinMedica Vitalize or Rejuvenize peels, or a shorter series of two or three Obagi Blue Peels. For a patient who no longer has oily skin, but has enlarged pores from a past condition, laser resurfacing may provide a faster result, and would be the preferred method. I believe, and research has shown, that the CO2 laser provides the best results with optimal safety for laser resurfacing. This is the laser that we use in our clinic.
