Retin-A + Under Eye Bags Q&A

Does Retin-A help tighten loose neck skin, hooded eyebrows, and under eye bags

I used tretinoin 0.025% on my face including the eye area. After around 4 weeks my under eye shadows became much worse (I already had dark shadows from naturally thin skin) and I now have awful bags under my eyes which I didn't have before. It looks as if I have lost subcutaneous fat and/or the skin has thinned. Is this a typical side effect of tretinoin and now I've stopped using it are the dark shadows and bags likely to improve? Thanks so much for your advice, it's much appreciated .

Is it possible to prevent or minimize the under eye bags that form as we age. For example, can diet, excercise, retin A, sunscreen, etc slow down the formation of eye bags as one ages?

I have never put in under my eyes to help with bags and dark circles. Can I use it under my eyes possibly mixed in with a moisturizer?

I am only 34 years old. I exercise regularly, drink lots of water, avoid salt, have worn sunscreen since my teen years and I have embarssingly shadowy under eye bags. Surgery is not an option, as my husband is completely against it. I have used Retin-A for a couple years now and I am wondering if I should quit and hope the under eye might improve?
