Opaque cosmetics may be used as camouflage for Mongolian spots.
The value of lasers in Mongolian spot is uncertain. However, in a retrospective study of 26 Japanese patients, the Q-switched alexandrite laser showed better outcomes in extrasacral lesions treated at a younger age.  The Q-switched ruby laser was used in the treatment of aberrant mongolian spots in 53 patients; it was more effective in exposed areas versus nonexposed areas. 
Intense pulsed light is also an effective method for the treatment of aberrant Mongolian spots.
