I must admit that for years I have been quite lazy with skincare and probably have done bare minimum. I’m getting closer to 40 and few months ago tried retinol serum in evenings and would use skin brightening oil or amino acid serum occasionally (I found my skin gets too sensitive if I use serums too often) and basic rich moisturising cream.
Although I don’t have very visible wrinkles yet apart one frown line which I always have had. On my forehead when looking close up I could start seeing mini lines which resulted in me trying retinol serum. I mainly used it only on mid part on my forehead and now I have started noticing that part of the skin where I use serum is very tight and sides are a bit “looser” (not sure how to even explain it lol).
Has anyone come across this? Should I try serum on full forehead or just keep using on more problematic area? I don’t necessarily want to use on all face as my cheek area is quite sensitive.
