I have 1/2 tubs of expired Tretinoin (0.05%)- it expired June 2012.Is it ok if I continue using it? I have a new tube of Tretinoin I've been using on my face (expiry date for Dec 2013), and was thinking it wouldn't "hurt" to use the expired Tretinoin on the backs of my hands at night?
I used to test that product in the lab. According to the stablility testing they are still good as far as active ingredient goes for well beyond 3-6 months after the expiration date. I wouldn't use it on the hands. Also, I wouldn't use it at all if the consistency changed or the emulsion separated. You can store the tubes in the refrigerator to slow the degradation process. It's definitely good for at least 3 months past the expiration date. After that they start degrading and if you don't know how you react to the degraded product, its best not to use it. Of course your dermatologist knows the best and will have the best answer for you! I would rather be safe than sorry.
Do not use the product on your hands. The skin cells are different than your face on your hands than on your hands. Please use the product as directed. We once had a customer who complained about an acne medication for face that he used on his butt cheeks. We laughed but we still had to run a battery of quality control test to prove the non expired product was still a quality product.
I am sorry, I don't know what's recommended for use on hands other than just SPF lotion. The only things I can think of is getting a mani and get a scrub and then do the parafin wax wrap on the hands. That used to soften my hands up really well. I miss getting that done. I am not even sure if salons do that anymore. Oh and of course drink plenty water.
Cransplash, about keeping it in the fridge, when I used to use it I always had to store in the fridge. That was the storage instruction on the tube. I am not sure which tube you have. My tube looked white with gray on the end but that was years ago.
