OOTD Triple Hyaluron Acid Serum Glowing Mask (1) is a single-serve sheet mask designed to deliver "deep, multi-layered hydration" and "natural radiance" through its triple hyaluron acid-rich serum. Its core features are:

1. Triple Hyaluron Acid Complex: The mask contains three molecular weights of hyaluron acid (high, medium, low) — high-molecular hyaluron acid forms a protective film on the skin surface to lock in moisture; medium-molecular penetrates the upper stratum corneum for long-lasting hydration; low-molecular reaches deeper skin layers to replenish internal moisture.
2. Serum-Rich, Skin-Fitting Sheet: The ultra-thin, breathable cotton or hydrogel sheet conforms tightly to facial contours (covering the T-zone, cheeks, and jawline). Each mask holds 25-30ml of concentrated serum, ensuring every area of the face receives sufficient hydration and brightening ingredients.
3. Hydration & Radiance in One: In addition to triple hyaluron acid, the serum includes niacinamide (vitamin B3) and glycerin — niacinamide brightens dull skin and evens tone, while glycerin enhances moisture retention, creating a dewy, radiant complexion after use.
4. Hygienic Single-Serve Packaging: Each mask is individually sealed to preserve serum freshness and prevent contamination. The compact size makes it easy to carry in a purse or travel bag, ideal for on-the-go skincare.
5. Gentle & Safe Formula: Free of alcohol, artificial colorants, parabens, and mineral oil — tested for skin irritation, suitable for frequent use (2-3 times a week) without damaging the skin barrier.

（specific ingredients are subject to product packaging; core components listed below）：
Key Hydrating Ingredients (Triple Hyaluron Acid):
High-Molecular-Weight Hyaluron Acid: Forms a protective film on the skin surface, preventing moisture evaporation and shielding against external irritants.
Medium-Molecular-Weight Hyaluron Acid: Penetrates the upper stratum corneum, replenishing moisture in the skin’s outer layers and relieving tightness.
Low-Molecular-Weight Hyaluron Acid: Reaches the deeper dermis layer, stimulating collagen production and providing long-term hydration from within.
Brightening & Moisturizing Auxiliaries:
Niacinamide (Vitamin B3): Inhibits melanin transfer, brightens dull skin, evens skin tone, and strengthens the skin barrier to enhance moisture retention.
Vegetable Glycerin: A natural humectant that attracts moisture from the air to the skin, maintaining long-lasting hydration and preventing dryness after mask use.
Panthenol (Vitamin B5): Converts to pantothenic acid in the skin, soothes mild irritation, repairs the skin barrier, and boosts moisture retention.
Mask Sheet Material:
Ultra-Thin Cotton or Hydrogel: Cotton sheets are lightweight, breathable, and suitable for sensitive skin; hydrogel sheets have higher serum-holding capacity and better adherence to facial curves.
Preservatives & Stabilizers:
Phenoxyethanol (≤1%): A mild, EU-approved preservative that inhibits bacterial growth in the serum, extending the product’s shelf life (24 months unopened) without skin irritation.
Disodium EDTA: A chelating agent that binds to metal ions in the formula, preventing ingredient oxidation and maintaining the stability of hyaluron acid and brightening components.
Harsh Substance-Free: Free of alcohol, artificial colorants, parabens, mineral oil, and sulfates (SLS/SLES) — meets global "clean skincare" standards, safe for daily use and sensitive skin.

Prepare the Skin: Clean your face with a mild cleanser and pat dry. Apply a toner (optional) to balance skin pH and open up pores for better serum absorption.
Apply the Mask: Tear open the package, unfold the sheet mask, and align it with your eyes, nose, and mouth. Gently press the mask to remove air bubbles, ensuring full contact with the skin (pay extra attention to the hairline and jawline).
Relax & Wait: Leave the mask on for 10-15 minutes (do not exceed 20 minutes, as the mask may dry out and reverse moisture absorption). Avoid facial movements (e.g., talking, laughing) to keep the mask in place.
Massage & Absorb: Remove the mask and gently massage the remaining serum into your face and neck with your fingertips until fully absorbed (no need to rinse — the serum continues to nourish the skin).
Follow-Up Care: For optimal results, apply a lightweight moisturizer or facial oil after absorption to lock in the hydration and extend the glowing effect. Use 2-3 times a week for sustained moisture and radiance.
