MOXIGUIMI 577+377 Whitening & Spot-Removing Niacinamide Essence (2g×10 single-dose ampoules) is a 5-in-1 essence specially formulated for all skin types troubled by dark spots and dullness, noticeable acne marks, uneven skin tone, sallow complexion, dry lines and fine lines, as well as damaged skin barriers.

It integrates the benefits of certified whitening, spot fading & removing, anti-wrinkle & firming, brightening & tone evening, and moisturizing & repairing.

Featuring a triple whitening and anti-wrinkle core consisting of 577 (the key component of Luceinol, the proprietary whitening ingredient of Pola), 377 (a potent tyrosinase inhibitor), and niacinamide, the product is compounded with soothing and moisturizing ingredients, innovatively building a three-dimensional whitening system of "dual-core melanin inhibition & spot fading + niacinamide anti-aging & repairing + single-dose packaging for freshness preservation".

It has obtained the China National Special Cosmetic Approval (Approval No. 20253263) and is clinically proven to deliver a 98.2% spot fading and brightening rate.

It can fundamentally inhibit melanin production, break down deposited pigments, promote collagen synthesis, and fade dry lines and fine lines.

Adopting a 6-free formula (alcohol-free, pigment-free, fluorescent agent-free, heavy metal-free, hormone-free, and harsh preservative-free), its single-dose ampoule packaging locks in freshness and prevents oxidation, with a precise 2g dosage per ampoule.

Boasting a fresh, fast-absorbing, and non-greasy texture, it is suitable for dry, normal, combination, sensitive, and barrier-damaged skin.

It completely breaks the common skincare pain points of slow whitening & spot fading results, skin irritation from harsh ingredients, serum oxidation and inactivation, and difficult dosage control.

Description

Core Ingredients: Golden Whitening Matrix Unlocks Radiant White Skin Core Whitening & Anti-Wrinkle Complex: 577 + 377 + Niacinamide 577 (Butylated Hydroxytoluene):

Melanin Breakdown Champion As the core component of Luceinol (Pola’s proprietary whitening ingredient), it effectively inhibits melanin production while breaking down deposited pigments.

It delivers remarkable results on stubborn dark spots and deep acne marks, with whitening power far exceeding ordinary ingredients.

377 (Phenylethyl Resorcinol):Tyrosinase Inhibitor Precisely inhibits tyrosinase activity, blocking melanin synthesis at the source to reduce dark spots and dullness.

When combined with 577, it achieves "melanin inhibition + breakdown" simultaneously, doubling the efficiency of whitening and spot fading.

Niacinamide: All-Rounder for Anti-Aging & Repair Assists in antioxidation and delays skin aging, while strengthening the skin’s moisture barrier to improve dryness and sensitivity.

It ensures whitening does not damage the skin, and also brightens skin tone and refines pores, realizing "whitening + anti-wrinkle + repair" in one.

Synergistic Soothing & Moisturizing Ingredients Formulated with mild soothing ingredients to relieve potential irritation from whitening components, reducing sensitivity risks.

Suitable for dry-sensitive skin and barrier-damaged skin.

Lightweight and hydrating formula provides moisture without greasiness, avoiding dryness and tightness after whitening, and achieving radiant whiteness and hydration simultaneously.

Full-Range Whitening & Brightening Inhibits melanin production at the source, improving uneven skin tone, sallow complexion, and dullness, revealing a natural, translucent radiant glow without an unnatural white cast.

Anti-Wrinkle, Firming & Fine Line Fading Niacinamide + core ingredients synergistically promote collagen synthesis, fading dry lines and fine lines, improving early aging sagging, and making the skin firmer and more elastic—combining whitening with anti-aging.

Moisturizing & Barrier Repair Replenishes skin moisture, strengthens the moisture barrier, and relieves discomfort caused by dryness, sensitivity, and barrier damage, making the whitening process gentle and burden-free.

Sensitive Skin-Friendly 6-free formula (alcohol-free, pigment-free, fluorescent agent-free, heavy metal-free, hormone-free, harsh preservative-free). Tested mild, it is safe for sensitive and fragile skin.

China National Special Cosmetic Approval: Reassuring Whitening Holds China National Special Cosmetic Approval (Approval No. 20253263), complying with national standards for whitening and spot-fading cosmetics. It guarantees both efficacy and safety, rejecting "conceptual whitening".

6-Free Formula: Mild & Non-Irritating Alcohol-free, pigment-free, fluorescent agent-free, heavy metal-free, hormone-free, and harsh preservative-free.

It reduces the risk of clogged pores and redness, suitable for sensitive skin and barrier-damaged skin.

Lightweight & Fast-Absorbing: Non-Greasy & Non-Pilling Watery, fresh, and translucent texture spreads easily and absorbs quickly without heaviness or greasiness.

It does not pill when layered with subsequent lotion, cream, or base makeup, adapting to various skincare and makeup routines.

Convenient Usage for Multi-Scenario Adaptation Daily Full-Face Whitening Morning and night after cleansing and toning, take 1 ampoule of essence and apply evenly to the entire face, massage gently until absorbed.

Follow with moisturizing products to improve overall dullness with consistent use. Targeted Local Spot Treatment For areas with prominent dark spots and acne marks, take a small amount of essence and apply it locally, massage gently to promote absorption.

It focuses on fading stubborn pigments for more precise results.

Intensive Whitening Cycle For severe dullness or obvious dark spots, use continuously for 10 days (1 box) as an intensive cycle to focus on brightening and spot fading.

Afterwards, use 3-4 times a week to maintain results. Pair with Sunscreen to Enhance Efficacy During whitening, pair with high-SPF sunscreen (e.g., SPF50+, PA+++) to avoid melanin regeneration caused by UV stimulation, ensuring long-lasting spot fading and whitening effects.

Matching Tips Pair with the same brand’s Natural Waterproof Sunscreen Lotion: Whitening + sunscreen work together to block melanin production and deposition, doubling the spot fading effect.

Pair with Moisturizing Repair Cream: For dry-sensitive skin, layer a rich moisturizing cream after using the essence to lock in moisture and nutrients, strengthen barrier repair, and avoid dryness.

Avoid Simultaneous Use with High-Concentration Acids & Retinol: It is recommended to use them alternately to reduce skin irritation risks and build tolerance gradually.
