377VC Whitening and Spot-Fading Serum
It integrates the benefits of whitening & spot-fading, brightening & tone evening, antioxidant protection, and barrier repair.
Featuring 377 (a potent tyrosinase inhibitor) and VC (highly active L-Ascorbic Acid) as the dual core melanin-inhibiting ingredients, the product is compounded with niacinamide, hyaluronic acid, and plant-derived soothing ingredients, innovatively building a three-dimensional whitening system of "dual-core melanin inhibition at source + antioxidant brightening + gentle repair".
It precisely blocks melanin production and breaks down deposited pigments, while fending off free radical damage, delaying photoaging, and improving sallowness and dullness caused by staying up late and sun exposure.
With a mild formula (alcohol-free, pigment-free, heavy metal-free), it boasts a fresh, fast-absorbing, non-greasy texture, making it suitable for dry, normal, combination, and mildly sensitive skin.
It completely breaks the common skincare pain points of "irritation caused by whitening and spot-fading products, short-lived brightening effects, and sticky, pilling serums"
1. Core Ingredients: Dual-Action Melanin-Inhibiting Matrix Unlocks Translucent Skin Core Whitening
Complex: 377 + VC 377 (Phenylethyl Resorcinol): Melanin-Inhibiting Core Potently inhibits tyrosinase activity, blocking melanin synthesis at the source.
It delivers remarkable results on dark spots, sun spots, and acne marks, with whitening power several times that of ordinary whitening ingredients.
Highly Active VC (L-Ascorbic Acid/VC Derivatives): Brightening & Antioxidant Champion Rapidly breaks down formed melanin, brightens skin tone, and improves dullness.
It also fends off free radical damage and delays photoaging, leaving the skin with a natural translucent glow.
Dual-Ingredient Synergy 377 focuses on "melanin inhibition" while VC emphasizes "skin brightening", covering both internal and external whitening needs.
This synergy doubles the efficiency of whitening and spot fading, delivering faster results than single-ingredient serums.
Synergistic Repair & Moisturizing Ingredients Niacinamide: Repair & Brightening Assistant Strengthens the skin barrier, improves uneven skin tone, and ensures whitening does not damage the skin. It also refines pores and enhances skin radiance.
Hyaluronic Acid + Plant-Derived Soothing Ingredients Deeply hydrates and locks in moisture, relieves dryness and tightness, and reduces the irritation risk of 377 + VC, making it safe for dry-sensitive skin.
Mild Formula Optimization Alcohol-free, pigment-free, heavy metal-free, and harsh preservative-free.
Tested mild, it lowers the risk of redness and clogged pores.
2. Four Core Efficacies: Precisely Solving Dullness & Dark Spot Pain Points Spot Fading & Removing 377 + VC work synergistically to break down deposited pigments, fading dark spots, freckles, sun spots, and acne marks. With long-term use, stubborn dark spots will gradually lighten, resulting in a more even skin tone.
Full-Range Whitening & Brightening Inhibits melanin at the source and brightens the skin surface, improving uneven skin tone, sallow complexion, and post-stay-up dullness.

Antioxidant & Anti-Aging VC + plant-derived antioxidant ingredients fend off free radicals, delaying dry lines and fine lines caused by photoaging, and combining whitening with anti-aging benefits.
Gentle Repair & Moisturizing Hyaluronic Acid + soothing plant extracts replenish moisture and strengthen the skin barrier, avoiding dryness and tightness after whitening.
The mild formula is suitable for various skin types.

Convenient Usage for Multi-Scenario Adaptation Daily Full-Face Whitening Morning and night after cleansing and toning, take 3-4 drops of serum and apply evenly to the entire face, massage gently until absorbed. Follow with moisturizing products.
Targeted Local Spot Treatment For areas with prominent dark spots and acne marks, take an additional 1-2 drops for focused spot application, concentrating on fading stubborn pigments.
