Understanding this, Keyshu developed Bioessence Mask Vitamin C—a specialized mask that supports improvement of dark spots and revives tired-looking skin. By combining pure biological actives with advanced delivery technology, the product offers an effective and safe brightening solution for all skin types.

Bioessence Mask Vitamin C works like an intelligent nutrient delivery system. Thanks to Nano Active Vitamin C, ultra-small brightening molecules can reach deeper into the epidermis. This optimizes antioxidant benefits and long-lasting brightness while remaining gentle on the skin’s natural protective barrier.

Who Should Use It?

Vitamin C Mask is designed to be compatible with every skin type, especially skin facing these concerns:

  • Dull, tired-looking skin with uneven pigmentation.
  • Post-acne skin with mild dark marks or long-term pigmentation spots.
  • Rough, dry skin losing elasticity and plumpness due to UV exposure and urban stress.
  • Anyone looking for an intensive brightening mask that remains gentle and safe for sensitive skin.

A Combination of “Golden” Actives and Unique Tencel Fiber Technology

With an intelligent mechanism, Bioessence Mask Vitamin C helps regulate the appearance of skin pigmentation, fade dark spots, and prevent new brown spots from appearing. It also provides essential nourishment that supports natural collagen synthesis, helping skin look firmer, smoother, brighter, and more refreshed.

Main ingredients of Bioessence Mask Vitamin C

Keyshu prioritizes pure ingredients with high biological compatibility:

  • Nano Active Vitamin C and Glutathione: A powerful antioxidant duo that helps neutralize free radicals and brighten the skin from within.
  • Niacinamide: A multi-functional active that helps refine pores and even out skin tone gently.
  • Saffron and seaweed extracts: Skin “superfoods” that help hydrate deeply and nourish the skin barrier.

Keyshu’s exclusive active Tencel mask sheet technology delivers essence retention up to 1050%. With a lightweight texture and face-hugging design, the mask helps every millimeter of skin receive nutrients efficiently while providing a relaxing experience.

Commitment to Safety and International Quality Standards

Every Keyshu product carries a promise of responsible care. Bioessence Mask Vitamin C is supported by reputable certifications such as Dermatology Test by Ellead Korea and Quatest 3 standards. These are strong assurances of safety, gentleness, and clinical efficacy.

How to Use for Best Results

To help skin absorb the full “nutrient feast,” Keyshu suggests this relaxing routine:

  • Start with deep cleansing: Remove dirt and sebum to free the pores and prepare the skin for Nano Vitamin C absorption.
  • Enjoy complete relaxation: Apply the mask and feel the soft, cooling touch of active Tencel fiber for 15–20 minutes.
  • Absorb and lock in nutrients: After removing the mask, gently pat the essence into the skin. No rinsing is needed.

Maintaining this habit 2–3 times per week is the key to skin that looks radiant, youthful, and full of vitality.
