CO2 laser resurfacing is a popular treatment for a variety of skin concerns, including large pores. The laser works by removing the outer layers of skin, which can help to stimulate collagen production and improve the texture and appearance of the skin. CO2 laser resurfacing can be effective in reducing the appearance of large pores on the nose, but the extent of improvement may depend on the severity of the pores and the individual's skin type and condition. In general, CO2 laser resurfacing is more effective in individuals with fair skin and mild to moderate pore size. It's important to note that CO2 laser resurfacing is a more invasive procedure and may require some downtime for recovery. You may experience some redness, swelling, and peeling after the treatment, but these side effects are temporary and should resolve within a few days to a week. If you're interested in CO2 laser resurfacing, I recommend consulting with a board-certified plastic surgeon who has experience with this procedure. They can assess your individual concerns and recommend the best treatment options for your skin type and condition. They can also discuss the potential risks and benefits of the procedure and help you determine if it's the right option for you. Best of luck ! Randal Haworth MD - Los Angeles, CA
