• CENTELLIAN24 is a "medical-grade skincare" brand under South Korea’s Dongguk Pharmaceutical, focusing on "Centella Asiatica + high-active moisturizing ingredients" as core technology and advocating the concept of "gentle and effective" skincare. This Hyal Waterfull Glow Gel Mask (5 pieces) from the Madeca Lab series is a star product in its moisturizing line, focusing on three effects: "multi-layer Hyaluronic Acid hydration + Centella Asiatica repair + brightening". Targeting three major skin pain points—dryness, dullness, and sensitivity—it adopts a refreshing gel texture, balancing "high moisturization" and "non-greasy" user experience, and is a cost-effective moisturizing mask "suitable for all skin types".

1. Multi-layer Hyaluronic Acid for Deep Hydration and Moisture Locking: Adopts a compound formula of "macromolecular + medium-molecular + small-molecular" triple Hyaluronic Acid—macromolecular Hyaluronic Acid forms a moisturizing film on the skin surface to isolate the dry external environment; medium-molecular Hyaluronic Acid penetrates the stratum corneum to replenish skin moisture; small-molecular Hyaluronic Acid penetrates the skin base to activate the skin’s own moisturizing ability, realizing a three-layer moisturizing system of "surface moisture locking, middle-layer hydration, and deep-layer water storage". Each sheet contains 30ml of high-concentration Hyaluronic Acid essence, maintaining long-lasting skin moisture.
2. Centella Asiatica + Brightening Ingredients for Dual Effects of Repair and Brightening: Adds the brand’s iconic 5000ppm high-concentration Centella Asiatica extract (Madeca), containing active substances such as asiaticoside and madecassoside, which can soothe skin redness and inflammation, repair damaged barriers, and enhance skin resistance; combined with niacinamide and vitamin C derivatives, it inhibits melanin transfer, improves dull and uneven skin tone, leaving the skin transparent and radiant after application, avoiding the single effect of "only hydrating without brightening".
3. Refreshing Gel Texture for All-Scenario Adaptation: Adopts gel mask sheet (not traditional non-woven fabric), with a thin texture like "second skin", closely fitting the facial contour (covering details such as eye area, nose wings, and jawline without dead ends); it carries sufficient essence without dripping, leaving the skin fresh and non-greasy after application, and can be directly followed by lotion/cream without washing (oily skin can also use it with confidence); 5 pieces of independent packaging, portable and hygienic, suitable for daily home use, business trips, travel, emergency hydration before makeup and other scenarios.

Core Active Ingredients:
Triple Hyaluronic Acid (Macromolecular + Medium-molecular + Small-molecular): Macromolecular Hyaluronic Acid (molecular weight: 100,000–200,000 Da) forms a moisturizing film on the skin surface to lock in moisture and prevent loss; Medium-molecular Hyaluronic Acid (molecular weight: 100,000–500,000 Da) penetrates the stratum corneum to replenish skin moisture; Small-molecular Hyaluronic Acid (molecular weight: 10,000–100,000 Da) penetrates deep into the skin’s basal layer, activates the moisturizing ability of keratinocytes, and the three layers work synergistically to achieve long-lasting moisturization.
Centella Asiatica Extract (5000ppm): Contains active substances such as asiaticoside, madecassoside, and asiatic acid. It relieves skin redness and sensitivity by inhibiting the release of inflammatory factors, promotes the activity of fibroblasts, repairs damaged skin barriers, and enhances skin resistance.
Niacinamide (3%): Inhibits the transfer of melanosomes to keratinocytes, reduces pigmentation, improves dull and yellowish skin tone. At the same time, it promotes the metabolism of the stratum corneum, enhances the skin’s moisture-locking ability, and prevents rapid moisture loss after hydration.
Vitamin C Derivative (Ascorbyl Glucoside): A mild Vitamin C derivative that does not require light avoidance during use. It reduces melanin production by inhibiting tyrosinase activity, brightens skin tone, improves uneven skin tone, and also has a certain antioxidant effect to delay skin oxidation and dullness.
Gel Matrix and Auxiliary Ingredients:
Glycerin, Butylene Glycol: Polyol-based humectants that work synergistically with Hyaluronic Acid to increase skin moisture content. They also improve the spreadability of the essence, making the mask sheet more adherent to the skin.
Carbomer, Xanthan Gum: Natural thickeners that form a refreshing gel texture, stabilize the essence system, prevent the essence from dripping or separating, and enhance the user experience.
Panthenol (Vitamin B5): A penetrating humectant that can penetrate deep into the skin’s basal layer to replenish moisture. It also soothes skin discomfort, promotes the healing of minor wounds, and strengthens the skin barrier function.
Allantoin: A mild exfoliating ingredient that accelerates the metabolism of aged keratin, improves skin roughness, and helps subsequent active ingredients penetrate and be absorbed better.
Dipotassium Glycyrrhizinate: An anti-inflammatory and anti-allergic ingredient that reduces the risk of skin sensitivity, relieves redness and stinging caused by dryness or irritation, making it safe for sensitive skin to use.
Safety and Packaging Ingredients:
Alcohol-free, Fragrance-free, Colorant-free, Mineral Oil-free, Parabens-free (adopts a "Phenoxyethanol + Hexylene Glycol" compound preservative system, which is mild and safe, and meets the standards for Korean sensitive skin skincare products).
Mask Sheet: Made of natural plant fiber gel sheet, which has good breathability, is skin-friendly and non-irritating. It can hold 30ml of high-concentration essence without deformation, and its adherence is far superior to traditional non-woven mask sheets.
Packaging Material: Food-grade polyethylene (PE) independent packaging bags, which are fluorescent agent-free and plasticizer-free. They effectively isolate external bacteria and dust pollution, ensuring the activity and hygiene of the mask ingredients.
(Note: The specific proportion of ingredients may vary slightly depending on the product batch; please refer to the "ingredient list" on the actual product packaging for details. All raw materials have passed the safety certifications of South Korea’s KFDA and international ECOCERT, and can be used with confidence by users with sensitive skin and pregnant women (after consulting a doctor).)

1. Pre-application Preparation: After cleansing, gently wipe the face with a mild toner (avoid irritating toner containing alcohol or acids) to open the skin absorption channel; take out the independently packaged mask, tear open the packaging and take out the gel mask sheet (some versions include an essence bag, which needs to be poured into the mask sheet bag for soaking before use), and gently unfold it to avoid pulling and deformation.
2. Mask Application Step: Align the gel mask sheet with the eyes, nose, and mouth to fit the face, and gently press from the center of the face to the sides with fingertips (focus on pressing the jawline, both sides of the nose wings, and the forehead edge) to ensure the mask fits tightly to the skin without air bubbles; the recommended mask application time is 15-20 minutes (do not exceed 25 minutes to prevent the mask from absorbing moisture back from the skin and causing dryness).
3. Post-application Care: Remove the mask, gently massage the remaining essence on the face with fingertips (about 1-2 minutes) to promote complete absorption of the essence; if the skin is oily or in summer, rinse the remaining essence on the face with clean water first, then apply lotion/cream to lock in moisture; if the skin is dry or in winter, directly apply lotion/cream to strengthen the moisturizing effect.
4. Usage Frequency: For daily moisturizing care, it is recommended to use 2-3 times a week; when the skin is extremely dry (such as seasonal changes, long stay in air-conditioned rooms) or for emergency hydration (such as before makeup, after sun exposure), it can be used continuously for 2-3 days (1 piece per day), then return to the regular frequency.
5. Precautions: Use the mask immediately after opening to avoid essence oxidation and invalidation; store in a cool and dry place (avoid direct sunlight or high-temperature humid environments, such as the bathroom) to prevent ingredient deterioration; if redness, stinging, itching or other discomfort occurs during use, remove the mask immediately, rinse the face with clean water, and consult a dermatologist if severe.
