how many milligrams of MB per drop?

On average, there about 25 drops per milliliter but it can vary. That particular solution contains 10mg/ml of methylene blue so if there were 25 drops in a ml each drop would contain 0.4mg. If you needed to know more accurately, you would need to measure out 1ml from their bottle in drops and then divide 10mg by the number of drops.

Can this be mixed in skin cream and used on skin?

This methylene blue solution is excellent quality for various applications. The 1% concentration is properly prepared and consistent. The dropper bottle design makes precise dispensing easy and prevents waste. I use this for staining specimens for microscopy work and it performs perfectly every time. The solution has good color intensity and stains reliably. The 1 fl oz size is practical - enough for numerous applications without excess volume that might degrade before use. The bottle is well-labeled with concentration and safety information. The dropper tip provides good control for adding exact amounts. I appreciate that this is properly formulated for scientific use rather than a questionable generic solution. The solution remains stable and doesn't show signs of degradation or precipitation. Whether you're doing microscopy, aquarium applications, or other uses requiring methylene blue, this is a reliable product. For hobbyists, students, or anyone needing quality methylene blue solution, this offers good value and proper formulation. The packaging protects the solution well during shipping.
