What is petroleum jelly made of?
Petroleum jelly (also called petrolatum) is a mixture of mineral oils and waxes, which form a semisolid jelly-like substance. This product hasn’t changed much since Robert Augustus Chesebrough discovered it in 1859. Chesebrough noticed that oil workers would use a gooey jelly to heal their wounds and burns. He eventually packaged this jelly as Vaseline.Petroleum jelly’s benefits come from its main ingredient petroleum, which helps seal your skin with a water-protective barrier.

the manufacturers of Vaseline take steps to purify their product. Vaseline is, therefore, safe for most people to apply to their face. However, it may not be suitable for everyone.

The benefit to apply it on face
Moisturizing
Petroleum jelly is an oil-based product that forms an oily film over the surface of the skin. This oily film seals in moisture, helping keep skin hydrated and soft.According to a 2016 review article, Vaseline prevents more than 98% of water loss from the outer layer of the skin. This type of water loss is known as transepidermal water loss (TEWL). In comparison, similar oil-based moisturizers, such as mineral oil and lanolin, reduce TEWL by about 20–30%Trusted Source.
Creating a physical barrier
The same oily film that seals in moisture also creates a physical barrier on the skin. This barrier protects against harsh elements and environmental pollutants that can damage the skin.
The risks
Increased breakouts
While Vaseline helps seal moisture into the skin, some experts have suggested that it may also trap in oil and dirt. As such, the American Academy of Dermatology (AAD) warn that people who are prone to acne may experience breakouts after applying Vaseline to the face.However, according to Vaseline’s company website, Vaseline is noncomedogenic, meaning that it will not clog or block pores.Nonetheless, people who have oily or acne-prone skin may not like the greasy feeling that Vaseline leaves on the skin.
 Skin irritation
According to a 2016 review, there are no reports of people experiencing a severe allergic reaction to Vaseline. Less severe allergic skin reactions are also rare.However, anyone who develops any of the following symptoms after applying Vaseline should stop using the product:
skin redness or soreness
itching
swelling or inflammation

Apply it on face on Eyebrows
​The benefits:
Moisturizing: The primary benefit of using Vaseline is that it's incredibly moisturizing.
Smoothes: As it smoothes onto and over your brows, Vaseline works to make even sparser brows feel and look much fuller. But it can also help the skin underneath by relieving dry skin or any redness.
Does Vaseline Work For Brow Growth?
If you're wondering how to make eyebrows grow faster with Vaseline, both experts note that there are no scientific studies proving it actually works for brow growth. That said, the salve can give your brows a fuller appearance. "Even though Vaseline has many beauty perks, including relieving topical skin conditions, it doesn’t do much to stimulate hair growth for your eyebrows," notes Chambers-Harris. "However, applying Vaseline can give the appearance of fuller brows because it can coat each strand making them seem thicker. It can also work as a brow gel, helping them stay in place."
Side effects:
Applying Vaseline to your eyebrows can create the illusion of moisturized, hydrated hairs and skin, but it could come at the expense of your pores. "It’s water-repellant and not water-soluble, meaning it will create a barrier so that moisture does not leave the skin," explains Chambers-Harris. "So, initially, you may feel instant gratification of a softened moisturized eyebrows, but prolonged use can lead to blocking moisture from getting to your brows and skin, which will ultimately lead to dry brows and skin." These clogged pores could lead to acne, milia, and bacterial contamination from unclean handling.

ways to use Vaseline in your makeup routine
LIPS
There are actually several ways to use Vaseline on your lips. For starters, it makes a fantastic gloss, and it's a sure way to keep your lips soft and supple. When you're out of your favorite gloss or simply want to highlight the natural color of your lips, a quick slick of Vaseline will give them a sheen like you wouldn't believe. Alternately, after applying your favorite lip color, you can dab a little Vaseline right at your cupid's bow and on the very center of your lower lip. This creates an automatic highlight that will make your lips look lusher and fuller.
THICK EYELASH
Now, this may be a beauty myth, but a lot of women swear by it and have had good luck with it myself, so I'm including it. There are countless products out there that promise to make your eyelashes grow, but some come with some thorny side effects—like making your iris brown—and others are pricey and worthless. If you want to up your eyelash game, just apply a layer of Vaseline before bed. In time, you'll see thicker, longer, and fuller eyelashes.

 MAKESHIFT EYE SHADOW
There are several ways to use Vaseline as eye makeup as well. You can apply it before putting on your eye shadow, so that you get a shiny, luminous effect. However, you can also use Vaseline in place of shadow. It's colorless, of course, but will create a soft, dewy sheen that works wonderfully when you're going for a more natural look. Just don't put it on too thick, because you don't want your eyelids to look greasy.

INSTANT HIGHLIGHTERVaseline makes an ideal highlighter as well, and obviously it will work with any skin tone! This, too, will give you a gorgeous, dewy look. All you have to do is apply a tiny bit of the Vaseline to the very tops of your cheekbones and to your brow bones. This will draw the light to all the right places, but it eliminates the need for pricy highlighter products.


  TRANSFORM MAKEUP PRODUCTS
You can also use this wonder-jelly to transform your makeup. For instance, if you have a blush color you adore, mix it with some Vaseline and try it as a lip gloss. You can do the reverse as well, and turn your lipstick into a blush. Naturally, you can also do the same with your eye shadows. I love this idea, because you can get blush or lipstick with some seriously vibrant pigment.
EYEBROW GELDo you have problems keeping your eyebrows in check? A little dab of Vaseline smoothed over your brows will tame them beautifully. It does double duty as an eyebrow gel as well, so it will set in any color created by eyebrow pencils or powders.

 VANQUISH SCALY SKIN
If you ever have a problem with dry skin showing scaly through your foundation, you'll love this trick. This happens to me along my T-zone and around my mouth, and I hate it – or hated it, rather, because Vaseline has saved the day again. Before applying your foundation, just smooth a little Vaseline over extremely dry patches. Dab your foundation or powder in those areas with a light touch and blend carefully, et voila! No more dry skin scales!
