Instance Norm Batch Size

I am using InstanceNorm3D in my model. Due to memory constraints I can use a batch size of only 1 and that is confusing me a bit. I know that batch size < 8 is not good at all for BatchNorm and can lead to poor results. I am not sure if the same holds true for Instance Norm. Can I use InstanceNorm with batch size of 1 and still expect correct results?
