Oh yes
On the joined image it was faked with the following ambient trick

#declare P_wax=pigment
               {
                  cylindrical
                  color_map
                  {
                     [ 0.25    rgb <1, 0, 0> ]
                     [ 0.5     rgb 1 ]
                     }
                  scale  0.2
               }
   #declare T_wax0=texture{
   pigment {P_wax}
   finish { ambient 0
            specular 1.0
            roughness 0.02
          }
   }
   #declare T_wax1=texture{
   pigment {P_wax}
   finish { ambient 1
            specular 1.0
            roughness 0.02
          }
   }

   #declare T_faked_sss =

   texture
      {
         spherical
         texture_map
         {
            [0.0 T_wax0 ]
            [1.0 T_wax1 ]
         }

      }
