MEDIHEAL - Vitamin C Essential Mask - 10  Count
MEDIHEAL Vitamin C Essential Mask 10PCS is a signature "long-term gentle brightening" set under the MEDIHEAL brand, with two core advantages: "stable Vitamin C derivative complex + 10-piece course-based care" and "brightening-moisturizing-soothing triple protection".
Core Formula: Stable Vitamin C DerivativesUnlike pure Vitamin C (L-ascorbic acid), which is easily oxidized and irritating, the mask uses a multi-component stable Vitamin C derivative complex (typically including Ascorbyl Glucoside, Magnesium Ascorbyl Phosphate). These derivatives:

Are stable in air/light (protected by the set’s opaque packaging) and do not oxidize easily;
Are mild to the skin, converting to active Vitamin C only after penetrating the stratum corneum, effectively inhibiting tyrosinase activity (a key enzyme in melanin production);
Avoid the "stinging" sensation of pure Vitamin C, making them suitable for most skin types.

10-Piece Course-Based DesignThe 10-piece set is designed for 4-6 weeks of regular care (1-2 times/week), which solves the problem of "intermittent brightening with single masks"— continuous use helps:

Gradually reduce melanin accumulation, improving long-term dullness;
Fade shallow pigmentation (e.g., post-acne marks) without causing excessive irritation;
Establish a gentle brightening routine for beginners.

Texture & Mask PaperEach mask contains 25-30ml of light, non-greasy Vitamin C essence, which is easily absorbed without stickiness. The mask paper uses MEDIHEAL’s patented ultra-thin cellulose material (0.1mm thickness), which fits closely to facial contours (even around the nose, eyes, and jawline) and has high essence-locking capacity— ensuring 90%+ of the essence is absorbed by the skin.
The set’s outer packaging is opaque to protect Vitamin C derivatives from light oxidation, and each mask is individually sealed for hygiene and portability. It is positioned as a "daily brightening essential for home use", meeting the needs of long-term dullness improvement and safe, gentle brightening for most skin types.

DIRECTIONS & USEPre-Use PreparationCleanse the face with a mild, non-irritating cleanser (avoid exfoliants or acidic products to prevent irritation );Pat the skin dry gently (do not rub vigorously);Optional: Apply a small amount of alcohol-free hydrating toner— this balances the skin’s pH and enhances essence absorption.
Mask ApplicationOpen the opaque single-sheet package quickly (to avoid Vitamin C oxidation from light) and take out the mask;Remove the two layers of transparent protective films (front/back);Align the mask with the eye, nose, and mouth cutouts, then press gently from the center to the sides (forehead → cheeks → jawline) to eliminate air bubbles— focus on dull areas (e.g., cheeks, around the mouth).
Absorption TimeLeave the mask on for 15-20 minutes (do not exceed 25 minutes, as prolonged contact may irritate sensitive skin);Avoid excessive facial movements (e.g., laughing) during application to prevent mask shifting.
Post-Use CareRemove the mask and massage the remaining essence into the face/neck for 1-2 minutes (circular motions) to promote absorption;Dry/mild sensitive skin: Do not rinse— follow with a fragrance-free moisturizer to lock in brightening effects;Oily/normal skin: If sticky, pat excess essence with a clean tissue, then apply an oil-free moisturizer;Critical Note for Daytime Use: Apply broad-spectrum sunscreen (SPF 30+) immediately after absorption— Vitamin C increases UV sensitivity, and sun exposure will reverse brightening effects.
10-Piece Course SuggestionWeeks 1-2: Use 1 time/week (let the skin adapt to Vitamin C);Weeks 3-6: Increase to 2 times/week (for continuous brightening);Pause for 1 week after finishing the set, then restart if needed (avoid overuse).
INGREDIENTSCore Brightening Ingredients (Vitamin C Complex)Ascorbyl Glucoside (AA2G): A water-soluble, stable Vitamin C derivative. Converts to active Vitamin C in the skin, inhibiting melanin production and brightening uneven skin tone— non-irritating, suitable for sensitive skin.Magnesium Ascorbyl Phosphate (MAP): Another mild Vitamin C derivative. Has anti-inflammatory properties while brightening, effectively fading post-acne marks and sun spots.Niacinamide (Vitamin B3): Complements Vitamin C. Blocks melanin transfer to the skin surface, enhances brightening effects, and strengthens the skin barrier— preventing dryness after brightening.
Deep Moisturizing IngredientsMulti-Molecular-Weight Hyaluronate: Small-molecule hyaluronic acid replenishes deep moisture; large-molecule hyaluronic acid forms a surface lock-water film— ensuring the skin stays plump while brightening.Glycerin: A natural humectant. Attracts environmental moisture to the skin, relieves dryness caused by Vitamin C, and maintains skin softness.Betaine: A plant-derived moisturizer. Has strong water retention capacity, soothes dry irritation, and balances moisture in low-humidity environments (e.g., air-conditioned rooms).
Soothing & Barrier-Protecting IngredientsCentella Asiatica Extract: Reduces skin irritation from Vitamin C, repairs the damaged stratum corneum, and enhances resistance to external stimuli.Panthenol (Vitamin B5): Converts to pantothenic acid in the skin, a key component of the skin barrier. Soothes sensitive skin and relieves tightness.Allantoin: Promotes skin cell renewal, softens rough cuticles, and soothes mild irritation— ensuring long-term use safety.
Safe Formulation GuaranteeParaben-Free, Alcohol-Free, Artificial Fragrance-Free, Mineral Oil-Free: Adheres to MEDIHEAL’s dermatological standards, avoiding ingredients that irritate the skin or destabilize Vitamin C— suitable for long-term gentle brightening care.
