Helping someone on Rasonque
The skin routine is the part most people need help with.
- Line up everything in the order it goes on: the antibiotic pill, the spray, two creams, moisturizer and sunscreen.
- Apply the triamcinolone cream and moisturizer to the back and trunk.
- Set two reminders a day, morning and evening.
- Know when to call the care team.
