How many sprays are needed to complete 1 mL of this serum in one use as that is the dosage instructed by my dermatologist
The number of sprays per 1 mL is not fixed, as spray pumps dispense different amounts depending on the bottle. To be accurate, measure once with a dropper or syringe to see how many sprays equal 1 mL for your product, then use that spray count consistently. Always follow your dermatologist’s instructions for correct dosing and application.
