I've been using Retin-A for 3 months in and I'm still peeling, is this normal?

I'm on my 3rd month of retin-A. Should I keep my every-night application of retin-A if my face still peels some days? The skin isn't dry or flaking, just small bits of skin that could easily come off if scrubbed. Is this normal even if I'm on my 3rd month of retin-A already or should I use it less often? I dont go under the sun, I dont have any irritation, redness, or itchyness. Just worried that the surface of my skin will become too thin or become too sensitive over time. Thank you
