HOW IT WORKS

Unlike regular vitamin C which is water-soluble and breaks down quickly, this form is oil-soluble, so it blends with your skin's natural oils and absorbs deeper into the skin layers. Once there, enzymes break it down to release active vitamin C, which slows pigment production, neutralizes free radicals, and supports collagen to maintain firmness. 2

KEY BENEFITS

Brightens Skin and Fades Dark Spots: Helps reduce pigmentation and even out skin tone by slowing the enzyme that triggers melanin production. 1,5
Supports Collagen and Fights Wrinkles: Promotes collagen production and helps block the enzymes that break collagen down, supporting firmer, smoother skin over time. 2
Absorbs Deeper Than Standard Vitamin C: The oil-soluble structure penetrates the skin more effectively than water-soluble vitamin C, reaching deeper layers. 2,6
Powerful Antioxidant Protection: Neutralizes free radicals caused by UV exposure and environmental stress, helping prevent premature aging. 1,2,6
