On my chest and breasts, I have enlarged pores. if I squeeze one of them, white liquidy stuff comes out, followed by blood, then there is blood left in my pore, after a few days the bloody pore turns black, like a blackhead. How do I treat this condition, how do I make the pores not retain blood? I use topical retinoids, benzyl peroxide, and salicylic acid scrub, but I would like to make the pores stop bleeding after the white stuff comes out.
