The only creams that will do you any good are the ones containing a derivative of Vitamin A or retinol. You can get prescription strength cream (Renova) and it will diminish the wrinkles over time but can be quite drying so start it gradually, maybe once every couple days, then after a couple weeks move on to once every other day and finally, when your skin gets adjusted, every day. It is supposed to work quite well. Make sure to use sunscreen when using Vitamin A creams because they make skin very sensitive to sunlight.
While waiting for results try disguising the wrinkle with some flirty bangs, very much in vogue right now.
