Will the cost of computation be very high in this case?
Yes, SSS is very expensive to compute. However, there are some realtime methods like Separable SSS: http://www.iryoku.com/separable-sss/
This website looks at how you might approximate the effect in Unity using translucency, affording convincing results at a relatively cheap cost.
