Purified Water, Witch Hazel
Ensure your hands are clean and dry and the bottle's seal is intact.
Gently pull the corner of your lower lid down and tilt your head back. Apply 2 or 4 drops into your lower eyelid.
Or, if you prefer, close your eye and apply 1 or 2 drops to the inner corner, then open and blink to spread the drops.
Replace the cap tightly.
Use as often as required.
