Hello, i have been using tretinoid 0.05% for the past 8 months and i find myself in a much worst situation than when i did start. I kept on thinking i just had to stick in there and things would improve. But i am now losing hope and wonder if i shall just not stop altogether. My skin is wrinkly, dry (even if I moisturize a lot) and feels ever more sagging. Are there any exceptions to Retin A working fab for older skin? Thank you
