Discrete permanent make up applied on men is an established fact.

Men enjoy (also) their male, natural appearance as:

• accent lashline enhancement: intensification at the upper and lower eyelid eyelashes: eyelashes get a fuller look when having little or
  no eyelashes, it seems that you are pale or little expression. You can consider a permanent treatment to enhance lashes. This is a kind of illusion effect giving you a fuller look to the lashes
• scarcover or camouflage in the face or elsewhere (see scar camouflage)
• camouflage or cover of vitiligo in the face, hands, on the body (see vitiligo)

Below you can see pictures where the lashes appear fuller through intensification enhancement in permanent make up
