VAS results are as follows : ( a ) color fading -- significant reduction in A within @ hours compared to B and C ( p = @ ) , ( b ) flattening -- more significant and earlier in A and C than B ( p < @ ) , and ( c ) mean reduction in size : significant in A and C at @ months ( p = @ , p = @ ) , @ months ( p = @ , p = @ ) , @ months ( p = @ , p = @ ) , and @ months ( p = @ , p = @ ) , whereas in B , it was seen only at @ months ( p = @ ) .
