NEW YORK -- Kale has crept out of salads and juicers and into beauty products from niche and mainstream sellers.

The leafy superfood that many love and others love to hate can now be had in face masks, skin-brightening serums, creams and nail polish, pushed along by the march to healthier living and the frenzy to fend off aging.

Kale hasn't displaced other botanicals, which remain a small segment of the multibillion-dollar beauty industry. There's a wide range of plant life and consumables in beauty products, but where else would the new darling in greens land if not beauty aisles, spas and websites?

A look at kale on the beauty side:

Kale for nails

Sprawled in ads on a bed of kale, British fashion darling Alexa Chung is the face of Nailkale, a new line of 12 nail shades from London-based Nails Inc. They just launched in the U.K. and will hit U.S. shelves in late August.

Nails Inc. founder Thea Green was inspired by a couple of trips to New York City last year.

"On one trip we saw a group of very lovely girls walking down the street all drinking their green juices, and no one in London was drinking green juice then,'' she said in a recent interview.

"Then I heard a woman in a restaurant, a very proper Upper East Side New Yorker, reject her salad because it was rocket (arugula) and not kale. I thought the whole thing was fascinating,'' Green said.

Green took kale for nails and its vitamins A, C and K to a laboratory and Nailkale was born.

"I think they thought I was a bit nutty.''

Nutty like a fox. She's the first to offer kale for nails.

Spa sales

Eminence Organic Skin Care sells luxury products to more than 3,000 spas worldwide. With roots in Hungary, that's where the company headed when it decided to work with kale farmers for two new products.

Stephanie Baresh, the brand and product creative director in Vancouver, Canada, said a cold processing method is used on raw kale for the Citrus & Kale Potent C+E Masque. The chunky green product offers a slight whiff of lemon with kale, avocado and spinach.

Eminence is focused on kale's antioxidant properties. Launched in June with the Citrus & Kale Potent C+E Serum, user feedback has been positive, she said.

"People will do anything to look good and to stop aging these days. This is a natural approach rather than getting Botox or plastic surgery,'' Baresh added.

The spas the company supplies were not a tough sell and include the Four Seasons Hotel in Westlake Village...
