Dehydrated skin tends to be limp and resistant, hindering optimal results. To mitigate this, it's essential to consume ample fluids such as water, juice, milk, or other hydrating beverages for the entire 48 hours before your appointment. Conversely, avoid dehydrating substances like pre-workout supplements, acne treatments, alcohol, and caffeine during this period. Additionally, consult your doctor about refraining from medications with diuretic effects leading up to your appointment.
