Pores
Visibility, congestion, and sebum balance
Pore size is largely genetic, but their visibility changes with oil production, sun damage, and dead-cell buildup. MIRU tracks pore visibility in your T-zone and cheeks separately — so you can see which actives actually reduce congestion.
What dermatologists assess
Pore diameter in T-zone vs cheeks
Presence of sebaceous filaments vs true blackheads
Oil shine distribution and timing
Skin texture smoothness under side-lighting
Top actives for pores
Oil-soluble — penetrates into pores to dissolve sebum plugs.
2% for regular use; lower concentrations for sensitive skin
Regulates sebum production, visibly shrinks pore appearance over 8 weeks.
5% concentration is well-studied for oil control
Clay (Kaolin, Bentonite)
Absorbs excess oil on contact, temporary mattifying effect.
Weekly mask — not daily, or skin over-compensates with more oil
Increases cell turnover, preventing dead-cell buildup that stretches pores.
Slow introduction — every other night for 2 weeks, then nightly
This reflects standard dermatological guidance. Educational, not a personal assessment.
