Skin reaction to products 😔

I recently received a Philosophy - Dose of Wisdom eye cream dark circle spot treatment to try out. However, after just two days of using it overnight, I noticed that the areas where I applied the cream got drier and darker. My mom even recognized the difference right away and pointed out the darker spot on my orbital bone. I guess it might not be suitable for my sensitive skin. Sadly, I have to stop using it now and hope that my face returns to normal soon. It has been a week since I stopped using it, but the burning and redness are still present. Can you suggest any actions that can help alleviate the allergic reaction when someone's skin reacts to a new skincare product?
