Core Ingredients:
Golden Antioxidant Matrix Unlocks a Brightening Experience Dual Antioxidant Powerhouses:
Astaxanthin + Ergothioneine 5% High-Purity Astaxanthin from Haematococcus Pluvialis:
A naturally potent antioxidant that penetrates the skin’s deeper layers to scavenge free radicals.
It blocks photoaging damage caused by UVA/UVB rays and blue light, reduces collagen loss, fades photoinduced fine lines, inhibits melanin transfer, and improves sallowness and dullness caused by staying up late.
Ergothioneine: Forms an "antioxidant golden duo" with astaxanthin to synergistically boost antioxidant efficacy. It defends against external pollution, stabilizes the skin’s underlying condition, lowers the risk of sensitive redness, and slows down skin aging.
Brightening & Soothing Synergistic Ingredients Glutathione + Tranexamic Acid:
Dual brightening agents that inhibit melanin production, fade acne marks, dark spots and uneven skin tone, revealing a translucent and even complexion.
Panthenol B5 + β-Glucan:
Soothes and repairs the skin barrier, alleviates mild irritation that may be caused by antioxidant ingredients, enhances skin tolerance, replenishes moisture, and improves dryness and roughness.
Sodium Hyaluronate + Hydrolyzed Collagen: Deeply hydrates and locks in moisture to plump the skin from within, improves dry fine lines caused by oxidative dehydration, and enhances skin elasticity and firmness.
2. Four Core Efficacies:
Precisely Targeting Oxidative Skin Concerns 98.2% Potent Antioxidation & Photoprotection: Astaxanthin and ergothioneine work synergistically to scavenge free radicals, defend against UVA/UVB rays, blue light and pollutants.
It reduces sagging, fine lines and dullness caused by photoaging, with over 92% of subjects reporting a noticeable slowdown in skin oxidation after use.
Root-Cause Brightening & Sallowness Reduction:
Dual brightening ingredients block the melanin pathway, improving the sallowness and dullness of stay-up-late skin, fading acne marks and dark spots.
Skin translucency is boosted by 35.7% in 28 days, revealing a natural, luminous glow.
Wrinkle-Reducing & Anti-Early Aging:
Reduces oxidative collagen loss, promotes collagen regeneration, fades dry lines, expression lines and photoinduced fine lines, enhances skin firmness, and leaves the skin looking younger and tighter.
Soothing, Stabilizing & Protective Care:
Combined with multiple repairing ingredients to strengthen the skin barrier, it relieves redness caused by external irritation. Suitable for antioxidant stabilization in various scenarios such as post-stay-up nights, daily commutes and seasonal changes.
3. Additive-Free Formula + Versatile Usage:
Antioxidation with Peace of Mind 12-Additive-Free Gentle Formula:
Free of fragrances, alcohol, pigments, mineral oil, silicone oil, preservatives, heavy metals, etc. Tested non-irritating for sensitive skin, it is safe for dry sensitive skin, oily acne-prone skin and post-medical aesthetic skin (the product appears pale red due to natural astaxanthin, which is a normal phenomenon).
Multi-Scenario Flexible Usage Daily Antioxidation: After cleansing and toning morning and night, apply 3–4 drops evenly to the face and massage gently until absorbed. Suitable for daily antioxidant protection of all skin types, especially ideal for post-stay-up night emergency care. Targeted Brightening: Apply the serum with a cotton swab on acne marks, dark spots and dull areas for concentrated brightening and fading, improving local skin tone uniformity.
Pre-Makeup Antioxidant Primer:
Mix 1–2 drops with foundation to create a luminous, long-wearing base, reducing makeup oxidation and dullness for extended wear. Device-Assisted Enhancement:
Use with an introduction device for circular massage to promote deep penetration of astaxanthin and strengthen antioxidant and wrinkle-reducing effects.
