Traditionally sought by consumers for their anti-aging benefits, nutricosmetics today appeal to consumers who believe that achieving glowing, radiant skin and strong hair and nails starts from within and is grounded in good nutrition. A growing spectrum of believers includes men and the young, a fortuitous change for a category that doesn’t see skin color, race or age—rather, nutricosmetics address wellness at a cellular level. Collagen and biotin are stalwart ingredients in the space, and growing in popularity, with other sector stars like vitamins A, B6 and E, coenzyme Q10 (coQ10), probiotics, and carotenoids like zeaxanthin and lutein emerging as well.
