Use Careprost 3ml only for the purpose specified on the product’s leaflet. Store the solution in a cool and dry place away from heat, light, and moisture. The eye drops should not be applied while you are wearing contact lenses. There should be a gap of at least 15 minutes between the application of the Careprost and putting the contact lenses back. Also, remove all your makeup before the application of an eyelash growth serum. Wash your hands properly before use and do not touch the tip of the solution bottle as it may lead to contamination. The solution may lead to unwanted hair growth in areas around your eyes that are exposed to the solution. Hence, the excess solution outside the upper eyelid margin should be removed with the help of a tissue or a cotton swab. There are certain drugs which may interact and affect the working of Bimatoprost. Therefore, it is best to disclose to your doctor about all the eye care products that you are currently using so that he/she can find out the possible drug interaction.
