I started using Tretinoin at the beginning of September and have had many weeks of breakouts although they seem to be slowing down (I hope!). I find it hard to dab a pea sized amount of the cream on my forhead, chin and cheeks and spread it all over my face. Can I mix it with moisturizer so that it will spread more easily all over my face? If so, which moisturizer works well? When did your skin stop breaking out? I use it every other night and sometimes I back off and use it every third night.
Don't mix it with moisturizer, as that will just reduce absorption. Plus retinoids tend to be pretty unstable... you don't know what effect the moisturizer will have.
I also find a single pea impossible to spread across my entire face. Just use more. The pea rule is there to minimize irritation. If you can handle more without irritation, then use more.
