Refill the bottle only after using up its contents. Do not wash the bottle or cap; wipe the bottle opening and transfer the entire refill at once. Do not mix with water or other lotions.
Cut open the pouch. Avoid gripping it firmly, as the contents may spill out.
Hold the bottle steady with one hand, insert the pouch spout into the bottle opening, and pour slowly.
For hygienic use, replace the bottle within one year or after five refills.
