[Skin Concerns] Do I have PIE or PIH?

Beauty Tips For Body Care
My marks are red. Some are deep red. So I assumed PIE.But then I tried "blanching" with a clear glass and the red marks stayed, even as I pushed hard against my skin. I always heard "red = PIE, brown = PIH"....but I do have very pale skin.So does that mean I have PIH?Also its been 2.5 months since my major breakout that caused these marks, is that too short to see any improvement?RoutineAM Spectro Blemish-prone Cleanser Spectro Blemish-prone moisturizer Neutrogena Sunscreen spf30PM Spectro Blemish-prone Cleanser Spectro Blemish-prone moisturizer Tret 0.025im also pretty sure I am sensitive to fatty alcohols, hence why no Cerave PM to combat red marks
