So, I've been using -derm for awhile now, and it obviously works faster on my black and grey tattoos, i just got a 12 hour session and its half b/g and half saturated color. the black and grey is healed but the color has ALOT of buildup. its been 4 days now and I've changed it every 24 hrs (which isn't the way i usually do it but was trying something a friend told me) but the buildup is worse the 3rd day, is it ok to let it sit in plasma if its ALOT?
Thanks
