Everything you should know about the powerful plant extracts.
First things first, what are essential oils?
Simply put: Essential oils are highly concentrated, volatile plant extracts obtained through different extraction methods, including steam distillation, which is the purification of a liquid via heating. A few popular elixirs include rose oil (which is derived from actual rose petals), lavender oil, and tea tree oil, but believe it or not, there are actually thousands of known essential oils with about 300 available commercially, all of which boast different health and lifestyle benefits, according to Adam Friedman, a dermatologist based in Washington, D.C..
How are essential oils used?
Great question: Essential oils can be used in many ways, and not just for skin care. “Essential oils can be diffused for inhalation, applied topically, or used for cleaning,” says New York City-based certified acupuncturist Mila Mintsis, who specializes in pain management and anxiety disorders.
According to dermatologist and founder of SmarterSkin Dermatology in New York City, Sejal Shah, it may be best to inhale essential oils if your concern is internal or emotional (lavender oil may be an excellent choice for this). “Clinical studies have shown that aromatherapy by inhalation can have real benefits for people with, for example, anxiety, [problems with] mental focus, depressive symptoms, and menstrual pain,” says Robert Tisserand, an essential oil educator and aromatherapy expert from California. He adds that using essential oils via bathing, diffusing, and topical application can also be helpful in terms of well-being.
When it comes to essential oils used in skin care, things tend to get complicated. While there are several oils that may aid in healing, toning, and brightening skin (Shah recommends tea tree, rose, rosehip, sandalwood, chamomile, and lavender), there are also elixirs that can spark serious skin reactions and even chemical burns due to allergies and phototoxicity.
“Phototoxic essential oils include bergamot [and citruses, like] lime and lemon, that should not be used at more than 0.5 percent on skin exposed to any amount of sunlight,” says Tisserand. (It’s also worth noting that the type of extraction used can actually determine whether a certain essential oil becomes phototoxic or not. For instance, when bergamot is cold pressed, it is phototoxic and when it’s steam-distilled it’s not.) “Phototoxic reactions can be pretty nasty, regardless of whether you have sensitive skin,” adds Tisserand. Shah says oils like cinnamon, clove, lemongrass, cassia, black pepper, and wintergreen can be irritating and recommends always using proper dilution and doing a skin patch test first.
