Retin-A + Arms Q&A

Hello, Long ago i was prescribed Tretinoin for face acne and would like to know if it's fine to use it also on my back, shoulders and arms, where i usually get pimples, or that skin is too sensitive. Thanks!

Can it reduce the size of a really big thick keloids, on arms, back, breast, legs and stomach?

I want to try retina-a on belly/arms stretch marks. I know it wont be miraculous but my stretch marks are still pink/reddish/blue color and im hoping it would help me heal them better. My question is what % is the best to use and how do i use it? Can i mix it with other cream like cocoa/shear butter? I will provide a picture of how they currently look. Thank you.

I know I definitely can not do facial waxing while on Retin A. But can I wax the rest of my body such as my arms, legs, bikini area, etc.?

I am a 64 year old female with naturally freckeld skin. I have extensive photo aging on my legs, arms, chest, and hands - crepey skin, loss of elasticity, many, many dark (age) spots, and wrinkles. Can I use Retin A on my legs, arms, chest, and hands all at the same time? Or might that result in too much systemic Retin A absorption? Any other suggestions? I have had several peels, and I have tried IPL for the spots, but neither has been very effective, and neither has had a lasting benefit. Thank you!

I am of Indian descent. I have scars on my arms and legs. They are not raised. Just discoloured. I can get a prescription from my dr for 7% (or even 14%) hydroquinone and Retin A. Will this help? Or is it best to use the hydroquinone with galaxal base on its own? Which will help the scars fade faster!? I am desperate. Summer is coming.
