25% potency ascorbic acid is tricky to stabilize. Most skincare companies wouldn't dare try it, but we did. The Beverly Hills Signature Collection Vitamin C25 Glow combines a low PH vitamin C with a 25% potency ascorbic acid, the highest available on the market. In addition, our Signature Strength Collection gets an added boost of vitamins B3 and B5 and includes therapeutic botanicals licorice, aloe, and chamomile. This remarkably high concentration of C diminishes dark spots instantly, stimulates skin regeneration, and jumpstarts collagen and elastin production. To top it all off, the cream shields and mends the skin from sun damage while providing it a refreshing drink of deep moisture. .
