Connecting microcomedones to my symptoms

New comedones can be forming even if no small bumps are currently visible

Microcomedones are difficult to see, so they cannot be counted from a single photograph. Instead, we look at the interval at which new comedones appear in the same area and the changes that occur when maintenance therapy is paused.

This is not a stage that can be removed by washing vigorously or squeezing them in advance

Rubbing the surface may only irritate the skin barrier. We monitor progress while combining treatments to reduce follicle blockage with efforts to create a skin condition that can withstand irritation.
