0.3% retinol in isopropyl Myristate stability

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.
