They seem to hold a darker color than before use of MT-2. At least that was my experience. Not sure if there's a good fix. Best solution I've found run KLOW, plenty of showers especially before bed, and wear a clean t-shirt to sleep in every night.
It's a thing on Reddit apparently 😅 it can't be that hard though. It's not rocket scientists getting overpaid at the clinic to shoot botulism into your face ♂️
