Keyshu Launches an Upgraded Version of the Centella Fiber Mask: Bioessence Mask Pre for Intensive Recovery of Sensitive Skin

Keyshu Is a Cosmeceutical Brand Providing Safe and Gentle Skincare Solutions

Keyshu is a Vietnamese biocosmeceutical brand pioneering the combination of natural-origin actives and purified biological actives to develop science-based skincare and skin-recovery solutions.

The brand cooperates with the Vietnam Institute of Pharmaceutical and Cosmetic Research (IPCR) during research, testing, and formula completion. Products undergo clinical testing to ensure safety and effectiveness on sensitive or weakened skin. The formulation process follows strict standards, from raw-material selection and active-purity control to formula-stability optimization.

Keyshu owns a diverse portfolio including masks, makeup remover, cleanser, toner, serum, sunscreen, bath salt, and many other products. In this ecosystem, Bioessence Mask Pre is developed as an intensive skincare step that quickly soothes and hydrates sensitive or treatment-stressed skin.

Bioessence Mask Pre – Intensive Recovery Mask for Instant Soothing and Superior Hydration for Irritated, Sensitive Skin

Bioessence Mask Pre is an upgraded version of Keyshu’s previous Bioessence Centella fiber mask. Designed for easily irritated or weakened skin, Bioessence Mask Pre helps quickly soothe redness, dryness, and discomfort while supporting the skin’s natural recovery ability. It is especially suitable during vulnerable periods such as redness, peeling, or after procedures like chemical peeling, laser, or acne treatment.

Outstanding ingredient formula of Bioessence Mask Pre

The mask formula focuses on actives that hydrate, reduce inflammatory responses, and reinforce the skin barrier. As a result, the skin is not only soothed immediately but also supported in rebuilding the epidermal structure, improving elasticity, and maintaining physiological moisture balance.

Suitable When the Skin Experiences:

  • Sensitivity, easy irritation, redness, or stinging.
  • Dryness, dehydration, and loss of elasticity.
  • Weakness caused by the environment or after peeling, laser, or treatment procedures.
    Skin that needs fast recovery and stronger barrier support.

Outstanding Effects of Bioessence Mask Pre:

  • Helps quickly soothe redness, irritation, and dryness.
  • Supports recovery and strengthens the skin barrier.
  • Deeply hydrates and improves dehydration.
  • Leaves the skin soft, smooth, and comfortable after use.
  • Helps improve elasticity and maintain skin balance.

Recovery Active Formula Combined with Biological Mask-Sheet Technology in Bioessence Mask Pre

The Bioessence Mask Pre formula is built around actives that soothe and restore sensitive skin.

The key ingredient is Madecassoside, a bioactive compound extracted from Centella Asiatica. It helps reduce inflammatory reactions, soothe irritation quickly, and support epidermal recovery. This active is combined with hydrating ingredients such as Panthenol (Vitamin B5) and Sodium Hyaluronate to maintain physiological moisture and strengthen the skin’s natural protection.

In addition, Palmitoyl Tripeptide-5 supports collagen production, improves elasticity, and helps the skin maintain a firmer structure. Antioxidant actives such as a stable Vitamin C derivative and Roman Chamomile extract contribute to soothing, tone improvement, and protection from environmental stress.

Biological mask-sheet technology of Bioessence Mask Pre

The product’s difference lies in its biological mask sheet made from Centella fiber combined with Lyocell. The sheet can hold essence up to 950%, helping nutrients spread evenly across the skin surface. Its soft, thin, face-hugging material improves absorption while creating a relaxing and comfortable masking experience.


How to Use Bioessence Mask Pre

To optimize soothing and recovery results, use Bioessence Mask Pre with the following steps:

Step 1: Cleanse the skin with facial cleanser and balance it with toner.
Step 2: Take the mask out of the package, unfold gently, apply to the face, and adjust it to fit closely.
Step 3: Relax for 15–20 minutes so the essence can absorb into the skin.
Step 4: Remove the mask and gently massage the remaining essence until fully absorbed.

Use 2–3 times per week or whenever the skin needs quick soothing and recovery.


Conclusion

The launch of Bioessence Mask Pre continues to complete the skincare and recovery solution system that Keyshu is building. If Cicamax Refine Serum serves as the foundational recovery step in a routine, Bioessence Mask Pre provides complementary support for fast soothing and intensive hydration for irritated or weakened skin.

By combining biological recovery actives with biological mask-sheet technology, the product helps reinforce the skin barrier and support a long-term balanced skin state. This is also Keyshu’s long-term direction: developing safe, scientific skincare solutions that suit Vietnamese skin characteristics and promote healthy skin from within.
