The Goodal Green Tangerine Vita C Dark Spot Care Gel Mask (5) is a "targeted brightening & dark spot care gel mask" launched by Goodal, focusing on solving dullness and dark spot issues with its core "Green Tangerine Vita C" ingredient system. Its core features are:

1. Core "Green Tangerine Vita C" Ingredient System: The mask contains 80% Jeju green tangerine extract (rich in natural vitamin C, 10x higher than ordinary tangerines) and stable vitamin C derivatives (3-O-Ethyl Ascorbic Acid)—the combination inhibits tyrosinase activity (a key enzyme in melanin production), fades existing dark spots, and prevents new hyperpigmentation.
2. Refreshing Gel Texture: Unlike traditional non-woven masks, it uses a hydrogel mask sheet—the gel texture is cool, lightweight, and highly adherent, fitting closely to facial contours without slipping. It delivers essence slowly (avoids rapid evaporation) and leaves no sticky residue after use.
3. 5-Piece Intensive Care Pack: The small 5-piece pack is designed for "trial use" or "short-term intensive care"—suitable for first-time users to test skin compatibility, or for targeted brightening before special occasions. Each mask is individually sealed to preserve the activity of vitamin C (a light/heat-sensitive ingredient).
4. Mild & Skin-Friendly Formula: Free of alcohol, mineral oil, parabens, synthetic dyes, and synthetic fragrances—reduces irritation risk for most skins. The pH is close to skin’s natural pH (5.5-6.5), avoiding disruption to the skin barrier.
5. Dual Effects: Beyond brightening and dark spot care, the green tangerine extract’s antioxidants help protect the skin from free radical damage (e.g., UV, pollution), while the gel’s moisturizing properties replenish skin moisture (avoids dryness from vitamin C).

• All skin types

• Made in :Korea

（specific ingredients subject to product packaging; common core components listed below）：Core Brightening & Dark Spot Care Ingredients:
Jeju Green Tangerine Extract (80%): Sourced from South Korea’s Jeju Island—rich in natural vitamin C (ascorbic acid), flavonoids, and polyphenols. It inhibits melanin synthesis, fades existing dark spots, and provides antioxidant protection against free radicals.
3-O-Ethyl Ascorbic Acid (Stable Vitamin C Derivative): A lipid-soluble vitamin C derivative—more stable than pure vitamin C (resists light/heat damage), penetrates the skin’s stratum corneum easily, and converts to active vitamin C to brighten skin and reduce hyperpigmentation.
Niacinamide (Vitamin B3): An auxiliary brightening ingredient—blocks melanin transfer from melanocytes to keratinocytes, further fading dark spots and improving overall skin tone uniformity.
Licorice Root Extract: A soothing brightener—reduces skin irritation caused by vitamin C, inhibits tyrosinase activity, and enhances the mask’s dark spot-fading effect.
Gel Mask Sheet Material:
Hydrogel (Sodium Polyacrylate-Based): A cross-linked polymer gel—highly absorbent (holds 10x its weight in essence), releases essence slowly, and has a cool, lightweight texture. It adheres tightly to the skin without slipping, ensuring maximum essence absorption.
Solvent & Moisturizing Ingredients:
Purified Water: The main solvent—undergoes multi-stage filtration to remove impurities, ensuring the stability of vitamin C and other active ingredients.
Glycerin & Panthenol: Moisturizing and soothing ingredients—glycerin attracts environmental moisture to the skin, while panthenol relieves dryness and irritation, balancing the potential drying effect of vitamin C.
Safety Assurance:
"5-Free" Formula: Free of alcohol, mineral oil, parabens, synthetic dyes, and synthetic fragrances—minimizes irritation risk for most skin types.
All ingredients comply with South Korea’s KFDA regulations and international safety standards (e.g., EU CosIng, US FDA). The product undergoes stability testing to ensure vitamin C activity is maintained throughout its shelf life.

Pre-Use Preparation (Key for Vitamin C Efficacy):
Cleanse your face with a mild cleanser and pat dry—avoid using exfoliating products (e.g., AHA, BHA) before use (may increase irritation from vitamin C).
For sensitive skin: Apply a small amount of the mask’s essence (squeezed from the pouch) to the inner arm or earlobe—wait 10 minutes to check for redness or tingling.
Apply the Gel Mask:
Tear open the pouch and take out the hydrogel mask (it has two layers: a protective film and the gel sheet)—remove the protective film (usually white or transparent).
Align the mask with your eyes, nose, and mouth first: attach the gel sheet to the center of your face, then smooth it outward to the cheeks, forehead, and jawline. Press gently to ensure full adherence (no air bubbles).
Wear Time & Post-Care (Avoid Sun Exposure After Use):
Leave the mask on for 15-20 minutes—the gel will gradually thin as it releases essence (do not wear until it dries completely).
After removing the mask, gently massage the remaining essence into your skin with your fingertips until fully absorbed (about 1-2 minutes). Do not rinse with water (to retain vitamin C and moisturizing ingredients).
Follow with a moisturizer and sunscreen (critical step!)—vitamin C increases skin’s sensitivity to UV, so sunscreen (SPF30+ PA+++) is essential to prevent dark spots from worsening.
Usage Frequency & Storage:
Use 2-3 times a week for intensive care (do not use daily—overuse of vitamin C may cause dryness).
Store in a cool, dark place (e.g., refrigerator door)—avoid direct sunlight or high temperatures (destroys vitamin C activity).
Warning:
Do not use on broken, inflamed, or sunburned skin.
If irritation (redness, itching, stinging) persists, discontinue use and consult a dermatologist.
