Vitamin C has long been beloved for its antioxidant properties, which provide myriad health benefits, from brightening skin to boosting immune support and protecting cells from damage.

As we turn the calendar year to 2026, Vitamin C is getting a boost in popularity. According to Spate, vitamin C products currently have a popularity score of 2.7 million with a 55.2% year-over-year increase in growth, ranking No. 4 among vitamins. Spate designates it as a “Sustained Riser,” meaning the trend shows reliable growth, even as other popular vitamin subcategories have a steeper trajectory. In healthy skin, vitamin C supports collagen synthesis and assists in antioxidant protection against UV-induced damage, making dietary intake an important complement to topical skincare, analysts say.

Proven Skincare is among the many brands jumping on the Vitamin C bandwagon. The brand’s latest product, SkinSpecific Vitamin C Radiance Complex Serum, delivers stabilized ascorbic acid and glutathione via a gold delivery system for enhanced skin penetration, helping protect against free radicals and providing a more radiant-looking complexion.

As Proven’s first standalone SkinSpecific product, this vitamin C serum arrives in time to help combat winter-related dullness, dryness and lingering environmental damage from summer, per brand officials. Key ingredients include niacinamide, a multi-tasking form of vitamin B that helps boost collagen production, reduce the appearance of hyperpigmentation, and support healthy barrier function; licorice root extract, an anti-inflammatory plant extract that can help fade sun and dark spots; and gold stabilized ascorbic acid and glutathione, an Ingredient complex with high antioxidant activity that helps boost collagen synthesis and protect against free radicals.
