has to be lengthening and make it look like i have eye lashes [SEP] i am picky about my mascara it has to be waterproof has to be lengthening and make it look like i have eye lashes it cannot cause irritation when i wear contacts the reason i tried this product was because i was out of mascara and was being adventurous in trying a new product this product was dark made it look like i had lashes and made them look longer i do not remember seeing anything about being waterproof but i wore it my first day when it was hot and i did not have black eyes by the end of the day i do not see much thickening going on with this product though my lashes are very thin and minimal due to wearing mascara for so many years i feel this product helped in making them stand out but not so much making them look thick and perhaps fake ish i began layering this on with my other go to mascara and it definitely helps not a bad product by any means just not your product if your main purpose is thickeningi did receive this product at a discounted price for my honest opinion no matter the price i paid for it all statements are truly my own and are no way altered people rely on reviews before trying a product and i believe in giving my honest opinion to help others make their decision just remember what works for some may not always work for others we are all different after all
