Aliases asks…Hi, new member here. I’m fascinated by your beauty blog with the fancy decos and infos. Perfect! Keep it up! I’ve read a lot of articles and watched many Youtube videos claiming that by applying Vaseline to your eyelashes and eyebrows every night before sleep helps to lengthen them. I wonder if it’s true? I know eyes are sensitive organs, so wouldn’t the chemicals in Vaseline, in this case Petroleum Jelly or mineral oil, enter the eyes and cause harmful health effects? Another curious question: I love your knowledge on beauty and skin and all these stuffs. Just wondering, what degree courses did all of you take?
The Left Brain replies:
Welcome to the Beauty Brains, Aliases! You’re not alone in your question about petroleum jelly helping eyelashes and eyebrows grow, I’ve seen that question from a number of women, in fact I’ve even blogged about this before but I think its worth revisiting.
Hair growth is difficult
Unfortunately this goes in the category of beauty myth. There is no plausible technical rationale why petroleum jelly (also known as petrolatum) would have any effect on hair growth whatsoever. So why is this myth so pervasive? My hunch is that women have applied this to their eyelashes and eyebrows and seen an apparent thickening effect. In other words, just like mascara, this oily substance can you make lashes stand out and look thicker. Since the oil also increases reflectance and shine it may make the lashes appear more dramatic. In theory, it could even be providing a little lubrication to lashes which helps keep them from falling off so soon.
Is petrolatum safe?
So if you do like this effect is it safe to apply these products as close to your eyes? I have also blogged before about the myth of petrolatum and mineral oil causing cancer. These are very safe ingredients as they are highly purified. The molecules are too large to penetrate through the skin and into your bloodstream. Of course, as with any product I would recommend keeping it out of the eye itself. Even the mildest products and have a stinging effect.
Finally, in response to your question about our education, the Beauty Brains have Bachelors of Science degrees in Chemistry and Master of Science degrees in Biochemistry. That technical scientific background combined with decades of experience in the beauty industry give us the knowledge to answer questions like yours.
