Redness on face F28. Super sensitive skin after damaging my skin barrier last year. For most of the year ive stuck to minimal skincare- ceramide creams and facewash, sunscreen.Two days ago my face became suddenly super red and the patch is getting darker too. No other symptoms of itch or burn, just this redness. I dont know what could have been the trigger but i recently tried a new lactic acid toner and a super high spf+80 sunscreen which i think is the probable trigger. Will this become melasma?
