Description
Engineered as a high-intensity, clinical treatment for stubborn hyperpigmentation and age spots, this concentrated ampoule unleashes an unparalleled brightening network. The liquid base replaces standard water with 75% vitamin tree water (hippophae rhamnoides water), creating an antioxidant-rich foundation that works synergistically with a massive 10% tranexamic acid (TXA) concentration. This clinical active operates on a cellular level to block the pathways that trigger pigment production, fading post-acne marks and long-standing discolorations over time.
To guarantee maximum stability and potency, the product isolates raw 100% pure glutathione powder inside a specialized cap structure. When mixed with the liquid ampoule—which contains an additional 3.8% liquid glutathione, niacinamide, and ascorbic acid (Vitamin C)—it forms a fresh, ultra-potent shield against cellular oxidation. Note: This high purity means the formula carries a distinct, pungent sulfur scent upon activation, which the brand proudly states is absolute proof of its raw power.
The water-light, fast-absorbing fluid glides over targeted areas effortlessly, sinking in completely flat without a sticky or heavy film. Backed by clinical trials, this intensive formulation is proven to fade persistent dark spots (even those up to 5 years old) by 16.38% within 4 weeks. Fortified with soothing panthenol, bisabolol, and tocopherol (Vitamin E), it achieves these dramatic corrective results while maintaining a gentle, non-irritating profile safe for sensitive skin.
How to activate and use:
- Activate: Press down firmly on the yellow cap button to break the internal vacuum seal, dropping the pure glutathione powder core directly into the liquid ampoule base.
- Shake: Shake the bottle vigorously for at least 20 seconds to completely dissolve the raw powder into the fluid matrix. Replace the yellow mixing cap with the precise clear applicator tip.
- Apply: Dispense a few drops over your clean, toned face. For beginners, it is recommended to mix a few drops into your regular moisturizer at first, transitioning to a direct standalone application once your skin adapts.
- Storage & Timeline: Because the active ingredients are freshly unleashed, you must use the bottle within 2 weeks of opening to ensure maximum efficacy and prevent degradation.
- Professional Tip: For ultimate brightening results, apply the Numbuzin No.5 Serum globally across the face, then layer this concentrated No.5 Ampoule directly on top of stubborn dark spots—this booster hack yields 39.23% better spot correction. Always follow morning use with a broad-spectrum sunscreen of SPF 30 or higher.
