I would like to inquire about a facial flushing treatment.

Back when I was a student, I went to a dermatologist because of whiteheads. However, I abused Vitamin C cream and steroids back then, which caused my stratum corneum to become extremely thin and sensitive. The facial redness is really stressing me out. My face turns bright red even after showering with just slightly warm water, and the flushing is so noticeable that I look really unfashionable overall. Are there any treatments for facial redness that you would recommend? I would appreciate it if you could tell me the name of the procedure, how many sessions are required, the cost, how long the effects last, and how often I need to get treatments. I considered going to a dermatologist before, but I thought it would be too expensive and worried about scarring, so I ended up not even getting a consultation. Please give me some recommendations!
