Does 0.3% retinol in isopropyl Myristate or CCT make a stable form of retinol product?

Thanks
Will it be stable if we don’t add antioxidants? -
It won’t be stable even if you add antioxidants and keep it in freezer. Retinol is utterly unstable. I am talking about actual retinol not derivatives. Tretinoin is even worse.
