Pauline: ELC= Early Learning Center, I bought it from Paragon, Level 5.
How many times did you apply? I used it on my girl every time after changing her nappy or bathe her. ;-)
One time in HCMC, she had allergy with toys (I played her to a playland and on the weekend it was crowded), after returning home, my girl get itchy on her legs and arms, I quickly bathed and applied for her, she stop scratching. ;-) And next day, it's gone. ;-)
