Some pores have lost their elasticity due to destruction of elastin around that pore. The result is a dilated, flaccid pore that is about 2 millimeters in width. This is very small, and it is likely the pore cannot contract back to its original state.
When this happens, we perform a small punch excision. We take a 2 millimeter punch biopsy. This biopsy takes the entire pore out, and brings normal skin, from either side of that pore, together. The dilated hole in the skin is removed and replaced with a small amount of scar tissue. The area then appears like a small, flat, line, or a 2 millimeter line, as opposed to a circular hole collecting debris and dead skin.
