WARNINGS AND PRECAUTIONS

For external use only. Avoid getting in the eyes. In the event of direct eye contact, rinse with cool water. Irritation, itching sensation and/or eye redness may occur. If you develop irritation, inflammation or swelling, on or around the eye, discontinue use. If irritation is significant, or at the first instance of any swelling, consult your physician.

Products containing prostaglandin analogs may cause iris discoloration.

A small number of users have reported eye redness and itchiness, dry eyes, watering of the eyes, sensitivity, styes, inflammation of the eyelid and eye, darkening of the skin around the eye area, hair loss, and visible enhancement of hair on or around or outside the application area.

Consult a physician before use if you are pregnant or nursing, are being treated for any eye-related disorder, are undergoing cancer treatment, are prone to dry eyes or styes, or have ever experienced conjunctivitis, eye infections, styes, or irritation from other cosmetics applied in the eye area.

Do not allow the tip of the bottle or applicator to touch fingers or any other surface. Contamination by common bacteria is known to cause infections.
