The NINE LESS B-Boost 1% Kojic Acid Serum is a precision-focused brightening treatment created for skin that struggles with dark spots, stubborn pigmentation, acne marks, and uneven tone. Instead of relying on one single brightening agent, this formula uses a layered, multi-pathway approach to discoloration—targeting melanin formation, pigment transfer, inflammation triggers, and post-spot dullness all at once.
At the heart of the formula lies 1% Kojic Acid, a well-known depigmenting active that works by inhibiting tyrosinase, the key enzyme responsible for melanin production. This makes it especially effective for sun spots, post-acne marks, and uneven tone caused by UV exposure or hormonal changes. Unlike harsh spot treatments, this serum is designed to be used consistently, thanks to its carefully balanced supporting ingredients.
To reinforce and stabilize the brightening effect, the serum is enriched with a high-strength 10% Niacinamide complex, helping regulate excess melanin transfer while simultaneously improving skin texture, pore appearance, and barrier resilience. This dual action means the skin doesn’t just look brighter—it becomes stronger, smoother, and more balanced over time.
The formula is further elevated with 2% Tranexamic Acid, an advanced pigment-control ingredient widely used in dermatological treatments for melasma and discoloration. Tranexamic Acid works on inflammatory pathways that often trigger recurring pigmentation, making this serum especially suitable for persistent or recurring dark spots rather than surface-level dullness alone.
To ensure the skin remains calm and comfortable during brightening treatment, 2% Panthenol (Vitamin B5) is added to deeply hydrate, soothe, and support the skin barrier. This makes the serum suitable even for users who are new to pigmentation care or who want visible results without dryness or tightness.
For radiance and antioxidant support, the serum includes Ascorbyl Glucoside (a stable Vitamin C derivative) and Glutathione, working together to enhance luminosity, neutralize oxidative stress, and promote a clearer, healthier glow. Over time, this combination helps skin appear more translucent, refined, and evenly lit from within.
The texture is light, fluid, and fast-absorbing, leaving no stickiness or residue. It layers effortlessly under moisturizers and sunscreens, making it ideal for both morning and evening routines. Whether used as a full-face tone-correcting serum or as a targeted treatment on pigmented areas, it integrates seamlessly into any skincare routine.
This serum is best suited for those who want visible brightening results with a formula that respects skin balance, making it a powerful yet refined choice within a results-driven skincare routine.
Think of it as your daily precision tool for clearer tone, refined radiance, and confident skin—without compromise.
