Cosmetics Formulation Development

I saw the brand MFeel Active Serum says that it can last up to 72 hours in one use, so I'm wondering if the one they sell will work for the same amount of time. I see the recommended rate is 0.5 to 4. Is this rate able to apply every day or not? Thank you.

Hello, it's the same substance. duration of action Depends on the wash. If there is no rinse It will stay on the skin for a long time. But if it is cleared Some may be washed away. Depending on the severity of the wash off too. Can be used every day
