Can you use Spooky cold laser through your clothing?

1. It has limited penetration. I do not know for certain but imagine it needs direct contact.

2. The light needs to shine on the skin. If melatonin in the skin blocks the light penetration significantly, as John said in the SAMA, then clothing will definitely block it, probably even more.
