Lynn,

Are you coming off synthetics? I have heard some reports of this type of phenomenon that you don't get with a natural that slurries like a JNat or some coticules. Maybe try that and see if you still get the sparkles.

i believe the idea is that some slurry will wear the tiny foil edge off. You might try following a sparkly with a JNat and see if it changes.

Cheers, Steve
