Beyond that, though, is the potential to use CBD as a tool to delay early signs of aging. “Inflammation is the basis of all skin disease, including aging,” she says. But while there’s a lot of hype surrounding CBD in skin care — and health in general — there is no cure-all. “Everything has its advantages and disadvantages or limitations,” says Dr. Gohara.
Finally, one of the newest uses for CBD skin care is in sunscreen. Dellavalle notes that it does make sense to add CBD to sunscreen, as its anti-inflammatory properties may help reduce the effects of a sunburn, such as redness. Of course, the idea is to apply sunscreen correctly (following guidelines from the American Academy of Dermatology), but in real life, many people miss areas, and applying a CBD-infused SPF may supply more general absorption and temper the reaction of sunburned spots, he says.
There are hundreds of other chemicals in the cannabis plant, and researchers don’t know what combinations are best. For instance, terpenes, the essential oils in plants (including cannabis), may exert synergistic benefits, suggests the Clinical Therapeutics study. “So much research needs to be done. We’ll be sorting this out for the next 25 years,” says Dellavalle. On the horizon with more research from universities and companies, says Jackin, may be more targeted and efficacious therapies for conditions like eczema and acne.
May Decrease Inflammation From Sunburns
First, let’s talk about what CBD is. Cannabidiol (CBD) is an active ingredient in the cannabis plant, according to Harvard Health Publishing. CBD can be derived from either medical marijuana or hemp. Although marijuana contains CBD, CBD doesn’t have psychoactive effects. (THC, tetrahydrocannabinol, is the chemical that causes the high.) All that said, CBD won’t lead to any mind-altering effects.
Along with being a potential therapy for inflammatory skin diseases, CBD is also featured in some anti-acne products. For instance, Mantra Mask's CBD Blemish Mask combines CBD and pimple-fighting tea tree oil. “There are CB2 receptors on sebaceous glands, which produce oil. According to research, CBD influences the sebum production of cells and has an anti-inflammatory component,” says Jeanette Jacknin, MD, a board-certified dermatologist in Solana Beach, California, who specializes in CBD skin care. This echoes findings outlined in articles previously published in The Journal of Clinical Investigation and Experimental Dermatology.
Unknowns About CBD Dosage
One of the touted functions of CBD is controlling inflammation. “The body has two CBD receptors that we know of: CB1 and CB2,” says Robert Dellavalle, MD, PhD, adjunct professor of epidemiology at the Colorado School of Public Health in Aurora. When applied to skin, CBD interacts with these receptors to turn down the inflammatory response. This happens by “decreasing the interleukins, which are chemicals that are like the immune system’s fire alarm that calls the fire department in an emergency. CBD may decrease the loudness of that fire alarm,” he explains.
In general, manufacturers add CBD to their products to give them a boost. “CBD is a very cost-effective way to enhance products,” says Austin Katz, cofounder of Sheabrand in Brooklyn, New York. CBD is in a range of products — those that claim to treat acne, dry skin, and eczema — because of its versatility. “I think we’re living in an era where people want to feel empowered to address their needs on their own,” he says.
Main benefits: Reduces inflammation, Regulates oil production, Neutralizes free radical damage.
What is CBD?
When buying a CBD skincare product, look for these words in the ingredients list, which indicate there’s actual CBD in the formula: CBD, hemp CBD, full-spectrum hemp extract, phytocannabinoid-rich hemp oil, and hemp extract oil.
Side Effects of CBD
Lewis and Schroeder are also fans of Kana, citing this this all-purpose face oil (which contains 100mg of CBD) as a favorite. "It's formulated with a ton of other powerful botanicals that help to hydrate skin and manage redness," they explain. "It’s a great addition to both your morning and nighttime routine."
