OK-432 does not work on micro cystic LM. If your daughter LM sort of looks like frog eggs, that is micro cystic. Lm will swell when child is going though hormone changes, an illness or stress.Also sorry to say LM is a life time thing there is no cure just very good management. If you like I have a few emails to other families, you can email me at wibearmom@yahoo.com Lora
