Before modern skincare products filled store shelves, many Dayak women were already caring for their skin with a traditional treatment known as Kasai Bisa.

Kasai Bisa, often referred to as the Dayak women’s face mask, is a local heritage product that remains widely used by women in Central Kalimantan. It is traditionally believed to brighten and nourish the skin from the outside while helping to prevent common skin problems such as redness and acne. In areas such as Kahayan Tengah, Dayak women have long applied Kasai Bisa as protection against direct sunlight while working in the fields. A few grains are dissolved in a small amount of water, ground until smooth, and then evenly applied to the face.

Kasai Bisa comes in several types, each with its own ingredients and purposes. One of the most common varieties is made from rice. This type is relatively easy to prepare at home and is often sold in traditional markets across Kalimantan. Based on an interview with Mrs. Turisia (57), a Dayak woman, Kasai Bisa has been produced for generations and is used for personal, family, and even community needs.

The production process is simple, as the ingredients are easy to find. Many families grow the necessary spices in their own gardens, and additional ingredients are readily available in traditional markets. The main components usually consist of finely ground rice mixed with natural spices and herbs such as turmeric, kencur, and aromatic leaves typical of Dayak tradition. All ingredients are processed manually and naturally, without chemical additives, making Kasai Bisa suitable for various skin types, including sensitive skin. The knowledge of preparing Kasai Bisa has been passed down from one generation to the next, making it a symbol of ancestral wisdom within Dayak culture.

Kasai Bisa can be applied directly to the face or body. It is commonly used before bathing or before attending traditional ceremonies. After being left on the skin for several minutes until dry, it is rinsed off thoroughly. Regular use is believed to cleanse the skin, maintain freshness, and remove dead skin cells. The natural ingredients are also thought to brighten the skin gently without damaging its outer layer.

As a traditional wet powder unique to the Dayak people, Kasai Bisa is made by soaking rice in clean water until soft, then grinding it together with turmeric or other traditional spices to form a thick paste. Once applied and allowed to dry briefly, it is washed away, leaving the skin feeling clean and refreshed.

In Dayak culture, Kasai Bisa is not only associated with beauty but also carries symbolic meaning. It is often used before traditional ceremonies, weddings, or certain rituals as part of physical and spiritual preparation. This reflects the Dayak understanding of beauty—not merely as outward appearance, but as an expression of cleanliness, simplicity, and respect for tradition.

Kasai Bisa is more than a traditional cosmetic product. It represents the cultural identity and local wisdom of the Dayak people. Preserving its use and the knowledge behind it means helping to safeguard an important part of Indonesia’s cultural heritage for future generations.
