As for the baby oil, if it is made of vegetable of natural plant's oil, it may be good for the growth of eyelashes. However, if the baby oil is made of mineral oil, it would only moisturize or solute the oily dirt, but no help with the eyelashes grow. I think if it really works with the plant oil, the effect may get by the use of long term. Why you use vitamin glue ball, it contains some fiber composition and would easily attach to the eyelashes available for the nutrients of eyelash growth. The principle of eyelash growth is the same with hair. The vitamin A, D, E is the necessary supplement for the eyelash growth. The vegetable oil contains such kinds of nutrients, so it would help with the eyelash growth. You would use vitamin directly to apply on your eyelashes and insist for some periods, it would make the eyelash strong and dense than before, more than one week's insistent will appear the effect to you.
