Core Ingredients:
Golden Brightening Matrix Unlocks Clear, Translucent Skin Dual VC Derivatives:
Core Brightening Complex 3-O-Ethyl Ascorbic Acid: An active VC derivative with excellent stability that requires no light avoidance.
It penetrates deep into the skin to inhibit melanin production, improving dullness, sallowness, dark spots, and acne marks. Ascorbyl Glucoside (AA2G):
Gently brightens the skin by converting into VC upon absorption, minimizing skin irritation. It also enhances skin radiance and evens out skin tone for a translucent finish.
Synergistic Ingredients Niacinamide: Reduces advanced glycation end products (AGEs), boosts antioxidant and brightening effects, improves uneven skin tone, strengthens the skin barrier, and enhances moisture retention.
Olive Leaf Extract + Diglucosyl Gallic Acid: Forms an antioxidant protective shield to defend against daytime photoaging, minimize skin damage caused by UV rays and blue light, and delay oxidative dullness.
Plant Extract Complex (Licorice Root Extract + Sakura Extract + Peony Flower Water): Soothes inflammation, alleviates discomfort that may be triggered by brightening ingredients, replenishes moisture, and nourishes the skin for a softer, smoother texture. 2. Four Core Efficacies:
Precisely Targeting Dull Skin Concerns Multi-Dimensional Antioxidation & Photoprotection:
The dual VC derivatives work synergistically with olive leaf extract to deliver a 92.3% free radical scavenging rate.
It fends off oxidative damage caused by UV rays, late nights, and screen blue light, reduces collagen loss, and delays skin aging.
Root-Cause Brightening & Sallowness Reduction: Dual VC derivatives combined with niacinamide block melanin production and transfer, boosting skin translucency by 31.7% in 28 days.
It improves stay-up-late induced sallowness and dullness, revealing a natural, luminous glow.
Dark Spot & Acne Mark Fading & Skin Tone Evening:
Precisely fades dark spots and post-acne hyperpigmentation, reduces the size of pigmented areas, and improves uneven skin tone for a clearer, more uniform complexion.
Moisturizing, Firming & Anti-Early Aging:
A blend of plant extracts and hydrating ingredients provides 24-hour long-lasting moisture retention, promotes collagen synthesis, fades dry fine lines, enhances skin elasticity and firmness, and improves roughness and dryness.
3. Additive-Free Formula + Versatile Usage: Brighten with Confidence 12-Additive-Free Gentle Formula: Free of fragrances, alcohol, pigments, mineral oil, silicone oil, preservatives, etc.
The natural, mild formula is safe for dry, normal, oily, and combination skin types. Sensitive skin can build tolerance gradually.
Multi-Scenario Flexible Usage Daily Brightening Care:
After cleansing and toning morning and night, apply an appropriate amount evenly to the face and massage gently until absorbed. Suitable for daily antioxidant brightening of all skin types.
Targeted Acne Mark Fading: Apply 1–2 drops with a cotton swab on dark spots and acne marks for concentrated treatment to accelerate pigment fading. Pre-Makeup Brightening 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 ingredients, enhancing brightening and wrinkle-smoothing effects.
Matching Tips: Pair with the same brand’s Bifida Yeast Water Gel Cream to strengthen barrier repair and moisture-locking effects; for advanced brightening, layer with niacinamide serum to achieve dual brightening + anti-glycation benefits for a more even skin tone.
