- Core Ingredients: Golden Spot-Fading Matrix Unlocks Even, Translucent Skin Core Spot-Fading Complex: High-Activity Tranexamic Acid + Multi-Dimensional Brightening Blend 5% High-Purity Tranexamic Acid (Cyklokapron): A medical-grade spot-fading ingredient that inhibits tyrosinase activity and melanocyte proliferation to reduce pigment production at the source. It also blocks melanin transfer to the epidermis, preventing pigment deposition that leads to dark spots and acne marks. Gentle and non-irritating, it’s safe for sensitive skin. Niacinamide + Glutathione Synergistic Enhancement: Niacinamide blocks pigment delivery pathways, improves uneven skin tone, and strengthens the skin barrier. Glutathione scavenges free radicals, provides antioxidant brightening benefits, and accelerates the metabolism of deposited pigments. Together with tranexamic acid, they form a "Spot-Fading Triangle" that triples spot-fading efficiency through three-pronged action. Vitamin B5 + Sodium Hyaluronate: Deeply hydrates and locks in moisture, relieving mild dryness that may be caused by spot-fading ingredients. It also repairs damaged skin base and enhances skin tolerance, making the spot-fading process gentler. Anti-Inflammatory & Stabilizing Ingredient Matrix Dipotassium Glycyrrhizinate + Centella Asiatica Extract: Soothes inflammation, reduces inflammatory reactions in acne-prone skin, and lowers the risk of post-acne hyperpigmentation. It also alleviates post-sun redness and seasonal sensitivity, stabilizing the skin’s microecology. Glycyrrhiza Glabra (Licorice) Extract + Arbutin: A dual plant-derived brightening complex that helps fade superficial dark spots and brighten skin tone. Combined with tranexamic acid, it delivers a dual effect of deep spot fading + surface brightening. Hydrolyzed Collagen + Oat Peptide: Replenishes collagen in the skin base, improves rough texture caused by pigmentation, and reveals skin with both faded spots and a smoother, more refined texture. 2. Four Core Efficacies: Precisely Targeting Multiple Concerns of Spot-Prone & Acne-Scarred Skin Targeted Spot & Acne Mark Fading: 5% tranexamic acid targets the root cause of pigmentation, achieving a 35.7% fading rate for stubborn dark spots and 42.3% for post-acne hyperpigmentation within 28 days. It effectively improves various pigmentation issues including sun spots, freckles, melasma, and acne scars. 91.5% of subjects reported lighter and smaller dark spots. Brightening & Skin Tone Evening: Tranexamic acid, niacinamide, and glutathione work synergistically to improve uneven skin tone and dull sallowness, enhance skin translucency, and reveal a natural, even, healthy glow. Anti-Inflammatory, Stabilizing & Repairing: Dipotassium glycyrrhizinate and Centella Asiatica Extract soothe inflammation, reduce recurrent breakouts in acne-prone skin, and lower the risk of new acne marks. They also repair the damaged skin barrier and enhance the skin’s ability to resist external irritants. Anti-Hyperpigmentation & Photoaging Defense: Multiple antioxidants work together to fend off photoaging caused by UV rays and blue light, inhibit post-sun pigmentation, and prevent spot recurrence. Ideal for high photo-damage scenarios such as commuting and outdoor activities. 3. Additive-Free Formula + Versatile Usage: Fade Spots with Confidence 10-Additive-Free Gentle Formula Free of fragrances, alcohol, pigments, mineral oil, silicone oil, preservatives, heavy metals, comedogenic ingredients, fluorescent agents, and irritating substances. Tested non-irritating for sensitive skin, it is safe for dry, oily, combination, sensitive, and acne-prone skin types. For sensitive skin, it is recommended to build tolerance gradually and increase usage frequency step by step. Four Practical Usage Methods Daily Spot-Fading Care: After cleansing and toning morning and night, take 3–4 drops of the stock solution and apply evenly to the entire face, focusing on areas with dark spots and acne marks. Massage gently until absorbed. Suitable for daily spot-fading and maintenance of spot-prone skin. Targeted Precision Spot Fading: For stubborn dark spots and hyperpigmented acne marks, dip a cotton swab in 2–3 drops of the essence and apply directly to the target areas 1–2 times daily. Concentrated treatment accelerates pigment metabolism and boosts spot-fading efficiency by 50%. Post-Sun Anti-Hyperpigmentation Repair: Within 72 hours after sun exposure, apply a thin layer of the essence to the entire face and pair it with a hydrating facial mask. Inhibits post-sun melanin production and prevents sun-induced darkening and spot formation. Device-Assisted Enhancement: Use with an introduction device or facial massager for circular massage to promote deep penetration of tranexamic acid, enhancing spot-fading effects. Especially suitable for skin with stubborn dark spots and deep acne scars.
