'L.S.' Dirt was formulated for the movie 'Life Stinks' starring Mel Brooks because there were so many actors and extras working everyday playing derelicts, and bums. Make up artist, Fred Blau, came up with a formula of cosmetic ingredients that could be sprayed on the face, neck, arm joints, etc. and in a matter of seconds the 'L.S.' Dirt fills the creases, wrinkles and pores for that dirty, greasy, sweaty look. VOILA!! INSTANT GRIME!!For darker applications use a dark brown or black pancake first and then spray with 'L.S.' Dirt.---YUK!!
