Does Microdermabrasion Shrink Large Pores?

Microdermabrasion with have little if no effect on the size of your pores. For reduction in appearance of your pores I would reccomened starting using a skin care brand containing Vitamin A. Products containing retinoids work to regulate your sebum production and in turn reduce the appearance of larger pores. Hope this helps.

A combination approach will give the most improvement. I recommend lasers, microneedling/PRP, Cosmelan, peels and skin care. I suggest getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Microdermabrasion cleans but does not shrink pores. On the other hand, TCA peels like the Obagi Blue peel, and lasers like the Sciton SkinTyte or BBL "forever young"and other IPL lasers do shrink pore size. See link for more information

In order to decrease the size of the pores, you may also consider chemical peels and other topical products.
There is no single laser that is consistently and clinically effective in eradicating large pores.
