If you have oily skin, don't write off facial oils completely. Grapeseed oil actually works to prevent oil production in the skin. This is because it has similar properties to the oils our skin produces naturally, says Stainhouse. Grapeseed oil helps create a negative feedback system, telling our oil glands that there is enough oil in the skin already and that they can stop making more.

"Grapeseed oil also has astringent properties that can make the skin feel tighter, as well as omega-6 fatty acids that can reduce inflammation and potential acne lesions," says Stainhouse. This ultimately leaves the skin feeling moisturized, but not greasy.

Jojoba oil is great for combination skin in particular as it helps retain moisture while controlling oil production. Like grapeseed oil, it is similar in composition to the skin's natural oils, and thus prevents our glands from producing too much grease.

Jojoba oil contains anti-inflammatory properties like vitamin E, vitamin B and fatty acids, as well as copper, which helps with skin repair. Plus, the product is incredibly lightweight and easily absorbs without leaving a greasy residue.

Tea tree oil is known best for its anti-bacterial benefits. "Some studies suggest that it is as effective at treating inflammatory acne lesions as 5 percent benzoyl peroxide," says Stainhouse. So if products like benzoyl peroxide and salicylic acid make your skin cranky, this might be a worthwhile option.

How does it work exactly? "Tea tree oil kills bacteria in the pores and deeper hair follicles where acne lesions can begin," Stainhouse explains.

Just keep in mind that since tea tree oil comes from a natural plant, you might be slightly allergic or sensitive to it. To be safe, Stainhouse recommends trying a test spot on your inner arm before applying it to your face.

Dealing with eczema? If you want to treat it naturally, calendula oil can help. "Derived from the marigold plant, this oil is soothing on inflamed, eczema-prone skin," says Stainhouse. Not all plant-derived oils agree with everyone's skin, but calendula oil rarely causes contact irritation or allergies, so feel free to go right ahead and use it.

Another skin-saver you can find right in your kitchen, olive oil is a rich product that helps deliver an intense dose of moisture to needy lips and skin.

It includes a slew of hydrating, anti-aging nutrients like squalene, omega-3 fatty acids, polyphenols and vitamins E. These work to exfoliate, encourage skin repair and prevent premature aging due to oxidative damage and inflammation.

Since it's a thick liquid oil, it is recommended for superdry skin and lips. Stainhouse suggests applying it at night.
