Texture changes in lighting

I’ve never dealt with this prior so asking to see if anyone has had experience with this and what it means. Overall, I have mild texture in daylight, for example natural lighting in the car I see some texture and mild indent but not anything crazy. When I use bathrooms at restaurant, with darker lighting etc for some reason my skin looks way worse. It scares me. I don’t know how to judge my skin by this. I am early in treatment - 3 months and have never had acne previously so this is all new for me. Does anyone have similar experience with texture etc? Any input is appreciated.
