4. Product Efficacy

• Whitening and Spot-Lightening: Effectively inhibits the activity of tyrosinase, blocking melanin synthesis at the source. It can also reduce oxidized melanin to a colorless form, achieving efficient skin whitening and fading pigmentation issues such as dark spots and acne marks.
• Antioxidation: Possesses strong antioxidant capacity, scavenging free radicals in the skin, preventing free radical-induced damage to skin cells, and delaying the skin aging process.
• Promoting Collagen Synthesis: After penetrating the dermis layer of the skin, it actively participates in and stimulates collagen synthesis, increasing the collagen content in the skin. This makes the skin firmer, plumper, and more elastic.

5. Application Fields

• Cosmetics Industry: Widely used in skin care products for whitening, spot-lightening, and anti-aging purposes, such as serums, lotions, creams, gels, and facial masks.

6. Usage Recommendations

• Addition Amount: Generally recommended to be added at 0.5–2% in formulations; adjustments can be made based on product positioning and efficacy requirements.
• Addition Method: It is recommended to add 0.2% sodium citrate to the formulation, and incorporate Ethyl Ascorbic Acid into the system at temperatures below 40℃ to avoid high-temperature-induced damage to its active ingredients.

7. Packaging and Storage

• Packaging: Typically available in 1 kg/bag or 25 kg/drum.
• Storage: Store at room temperature, away from light, and in a sealed container. The shelf life is generally 24 months under proper storage conditions.
