Core Formula: Stable Vitamin C Derivatives

1. Are stable in air/light (protected by the set’s opaque packaging) and do not oxidize easily;
2. 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);
3. Avoid the "stinging" sensation of pure Vitamin C, making them suitable for most skin types.

10-Piece Course-Based Design

• 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.

1. Core 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.
2. Deep Moisturizing Ingredients
Multi-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).
3. Soothing & Barrier-Protecting Ingredients
Centella 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.
4. Safe Formulation Guarantee
Paraben-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.

Pre-Use Preparation
Cleanse the face with a mild, non-irritating cleanser (avoid exfoliants or acidic products to prevent irritation 叠加);
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.
2. Mask Application
Open 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).
3. Absorption Time
Leave 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.
4. Post-Use Care
Remove 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.
5. 10-Piece Course Suggestion
Weeks 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).
