產品亮點

• Sustained-release technology allows vitamin C to dissolve slowly for stable blood concentration over extended periods

• Vitamin C participates in collagen synthesis, promotes iron absorption, and enhances immune defense function

• Ideal for sustained whitening antioxidant effects and immune maintenance through efficient daily vitamin C supplementation
