Drop the essence on a stack of tissue paper or cotton pads to observe the penetration, the easier it is to penetrate downward, indicating that the molecule is small, the penetration is strong and it is easy to be absorbed.

If it only spreads on the surface, it means that the penetration is poor and it is not easy to absorb.
