If you are going the oil route for your complexion, it's important to pay a little more attention to your cleansing M.O. Barba is a fan of double cleansing, not only to remove excess residue from any oil-based products, but also to completely clean off makeup and the rest of the day's gunk and grime.

Seems like too much work? Gohara points out that most cleansers these days contain surfactants that are specially made to break down oil. Some of them -- like the commonly vilified sodium lauryl sulfate -- can be harsh on skin, but she notes that there are many other, gentler surfactants out there (glycinate and sodium lauroyl isethionate are two common ones).

Alternately, use a cleanser that contains salicylic acid: "It's lipophilic, meaning it will break down any oil, be it the sebum that your skin is naturally producing or leftover residue from a product," Gohara says.

But can't you use coconut oil as a cleanser? Yep, and we'll be the first ones to point out that it makes an especially effective eye makeup remover, but because it doesn't break down with water (you know, the whole oil-and-water-don't-mix thing), it can leave a film on your skin. It's possible that that film -- or the film from any other oils you're using -- may then affect the penetration of products you apply on top, says Barba.

"In a worst case scenario, it can create a type of dilution, where it makes any skin care products or active ingredients you use afterwards less effective," she explains. "And if you're spending lots of money on an expensive serum, that's the last thing you want."

To that point, if you want to use coconut oil as a cleanser, follow with a regular cleanser after. If you're using other types of skin care oils, make them the final step in your regimen (or second to last, before sunscreen, if you're using them in the morning).

Skin aside, slathering coconut oil on your strands should be fine, right? After all, there's no risk of breakouts... or is there?

While it's commonly recommended as an at-home hair mask and remedy for dry, brittle hair, you want to make sure that it doesn't end up inadvertently causing breakouts on your bod, cautions Barba. "If you are using it in your hair, make sure to thoroughly wash your back, neck, and chest after you rinse it out to remove any excess residue."

If all of this oil info is making your head spin, we don't blame you. A foolproof solution if you want to play it safe? "Choose oil-based products, rather than pure oils," recommends Gohara. "Let the beauty companies do the work for you. They can formulate a cosmetically elegant product that will allow you to reap the benefits of an oil, without having to worry about the downsides."

Plus, because oils have the potential to oxidize (as do most other active skin care ingredients) you want to make sure they've been properly formulated in a way that ensures they're going to remain stable and effective, adds Barba.
