Thanks very kindly for your thorough answer to the question I posed earlier today. I'm sorry to both you again, but I forgot to tell you that I have microdermabrasion every two weeks (with every other medical facial that I get weekly) for the past 20 years and IPL every four weeks for about 15 or 16 years now. Still, I have the pores....and the wrinkles. (As you can see, I have spent a FORTUNE on all this for decades now--peels, lasers, IPL, microderm, facials, prescriptions, a careful at-home regimen, etc.) My dermatologist says that at this point, I cannot possibly have any oil clogged in the pores and that what's going on to cause the enlarged pores, as well as the general laxity, is a loss of elastin and collagen, from age, and that the CO2 will improve this situation. But it seems you disagree. And do you think that the CO2 won't help the wrinkles and fine lines either? Sorry for the multiple posts. And thank you for your valuable time!
