Three and a half years ago i used Epiduo on my forehead, temples and nose. I did expose to 45 mins of morning sun without spf.
My skin turned red, then brown. The inflamation/irritation still persists. I can feel the skin thicker (like inflamed skin feels like) when i raise my eyebrows. The area looks brown. It becomes more red when i touch it.
Texture on those areas is different and the skin is a little raised.
I've tried azelaic acid 20%, ascorbic acid 20%, kojic acid, glycolic acid, salicilyc acid, tranexamic acid, adapalene, tazarotene 0,1%, hidroquinone which made it worse, mercury bleaching cream, BBL, laser peel (resufacing), flucinolon.
I think flucinolon worked best, but i can't use it long term on my face. When i use it, the inflamation and hyperpigmentation subside, but effects are immediatly reverted if i stop using it.
