What It Does

Fades Dark Spots & Blemish Marks — Contains refreshing capsules that effectively deliver active ingredients deep into the skin, helping with the care of blemishes, freckles, dark spots, and skin troubles The Alpha-Melight™ brightening capsules burst on contact with skin, releasing a concentrated dose of brightening actives precisely where they are needed most.

Brightens & Evens Skin Tone — Contains 82% of Korean Yuja Extract for brightening and moisturizing — with 5% of Niacinamide to brighten up skin, and prevents the forming of melanin with Glutathione and Arbutin.  Four distinct brightening pathways working simultaneously for the most comprehensive anti-pigmentation action in a single serum.

Controls Sebum & Minimizes Pores — 10% of Niacinamide helps to improve the skin's overall texture, minimize the appearance of pores, regulate oil production, and enhance the skin's natural barrier function.  The patented BRIGHT OLÉOACTIF complex adds an additional sebum-control layer that keeps pores clear and shine in check throughout the day.

Gently Exfoliates & Smooths Texture — 83% of Yuja Extract contains natural fruit acids that can gently exfoliate the skin, promoting a smoother and brighter complexion.  The natural AHA activity of Yuja progressively refines rough texture and unclogs pores — without any of the irritation of conventional exfoliating acids.

Dual Moisturizing Mechanism — Provides a dual moisturizing mechanism, filling in skin dryness and forming a moisture barrier on the skin's surface, resulting in improved hydration and the prevention of moisture loss.  Trehalose, Panthenol, and Glycerin work from the inside out while the surface barrier complex locks everything in.

Revitalizes with 12 Vitamins — 12 types of vitamins revitalize and soothe your skin for a fresh and dewy complexion — Vitamins B1, B2, B3, B5, B6, B7, B9, B12, C, E, and more flood skin with the complete nutritional spectrum it needs to function at its best, glow consistently, and resist daily stressors.

Key Ingredients

Yuja Extract — 83% (Citrus Junos Fruit Extract) — The extraordinary base of this formula and the ingredient that sets it apart from every other brightening serum in K-beauty. Yuja — also known as Yuzu — is a Korean citrus fruit celebrated for centuries in hanbang tradition for its skin-brightening and immune-boosting properties. Rich in Vitamin C, it strengthens immunity, enhances skin elasticity, and provides deep hydration — with high antioxidant activity that helps combat pigmentation and post-acne marks.  At 83%, it doesn't just appear on the ingredients list — it IS the formula.

Niacinamide — 10% — The niacinamide ingredient has been strengthened by double the concentration, maximizing its glowing effects and targeting areas with pigmentations for effective care, resulting in the reduction of visible traces.  At 10%, this is the highest clinically effective Niacinamide concentration — delivering maximum pore refinement, sebum control, dark spot fading, and barrier strengthening simultaneously.

Glutathione — The "master brightener" — a powerful antioxidant that suppresses Tyrosinase enzyme activity to directly inhibit melanin synthesis, neutralize free radical damage, and deliver progressive complexion-clearing results that build with every application.

Arbutin — A gentle, plant-derived brightening active that interrupts the melanin production pathway upstream — preventing new dark spots from forming while fading existing ones, particularly effective for post-acne hyperpigmentation and sun damage.

BRIGHT OLÉOACTIF™ (Patented) — The patented ingredient BRIGHT OLÉOACTIF functions to control sebum and reduce dark spots — a proprietary blend that works at the sebaceous gland level to regulate excess oil production, keep pores clear of congestion, and prevent the sebum oxidation that contributes to post-acne pigmentation.

Alpha-Melight™ Brightening Capsules — Visible micro-capsules suspended within the serum that burst upon skin contact, releasing a concentrated payload of brightening actives directly into the pore and surrounding skin surface — a delivery innovation that dramatically improves the bioavailability and targeted efficacy of the formula's active complex.
