Now that nine states and the District of Columbia have legalized recreational marijuana, and with many other states with varying latitudes of access, cannabis has gotten a whole lot more sophisticated. And the beauty business is not about to miss out.

Cannabis-derived ingredients feel trendy, and they may well offer a raft of possible benefits, which beauty brands are quick to tout. CBD oil, specifically, is nonpsychoactive (it won’t get you high) and is said to offer relief from pain, anxiety and depression, stimulate appetite and have anti-inflammatory and anti-acne properties. Cannabis products also nod to enthusiasms that have already gained momentum in the beauty industry, like ingestibles (CBD-infused gummies, caramels and drops) and wellness (CBD lotions to relieve soreness from new year workouts).

There are already devout fans, some boldfaced, who are drawn to CBD topical products largely for their pain-relieving properties. Olivia Wilde recently told this reporter that she used it to relieve physical aches during a Broadway run. The fashion stylist Karla Welch, who works with Ms. Wilde, Ruth Negga, Katy Perry and Sarah Paulson, uses Lord Jones CBD lotion on her clients’ feet when they walk the red carpet.

“It’s perfect for long nights in high heels,” Ms. Welch said. “All my girls love it, and bottles live in my styling kit.”
