Description
Natural Essence, Unparalleled Cleansing: Agar Agar Foam Cleansing by SISEUNDEUSI
Traditional Korean Extraction Method for Maximum Benefit
SISEUNDEUSI sets itself apart by employing a unique extraction process. Natural ingredients are more effective when extracted correctly. We use the traditional Korean double boil method, ensuring each essence is deeply and richly extracted over 48 hours. This meticulous process guarantees the full potency of the ingredients.
Optimal Blend of Wild Herbs
We’ve perfected the blend of 20 types of wild and medicinal herbs through 30 years of extensive research. Our unique technology and know-how ensure the optimal ratio for maximum efficacy. These herbs are naturally dried, away from sunlight, to concentrate their active components. SISEUNDEUSI matures these herbs for three years, unlocking their full potential.
From Cultivation to Completion: A Seven-Year Journey
Our commitment to quality starts from the very beginning. We cultivate and directly manage about 20 types of wild and medicinal plants. This entire process, from cultivation to product completion, spans seven years, ensuring the highest quality for you and your family. The stages include:
- Cultivation of wild plants.
- Three-year maturation period.
- Traditional 48-hour double boil method.
- Essence extraction with agar.
- Final product completion.
Unique Utmut Agar Collection and Processing
Our agar agar, key to our cleanser, is sustainably collected by female divers off Jeju Island. The processing involves repeated freezing and thawing, resulting in a product made with the purest agar.
Certified Organic Ingredients
Our product proudly boasts the Longoon Tiles OTCO certification, completed under the supervision of the U.S. Department of Agriculture. This highlights our commitment to using only the finest ingredients. The key ingredient, American OTCO organic certified aloe vera, ensures a gentle yet effective cleansing experience. OTCO (Oregon Tilth Certified Organic) certification is a testament to our dedication to organic practices. It is awarded only to products that have been produced without the use of pesticides or synthetic fertilizers for a minimum of three years. This rigorous process guarantees the purity and quality of our ingredients, contributing to the overall effectiveness and safety of our cleansing foam.
Benefits of Agar Agar
Agar agar is excellent for breaking down oils and impurities while providing post-wash moisture. Our cleanser is:
- Collected by Jeju divers from natural sources.
- Slightly acidic, mimicking natural skin pH.
- Rich in phospholipids for strong cleaning power.
- Protective, preventing skin moisture loss.
Natural Formulation
If the cleanser hardens at the pump, it’s a sign of our commitment to avoiding chemical processing. The slipperiness post-wash is due to the protective mucilage from agar and kelp, not cleansing agents. It’s recommended to leave it on the skin.
Tested and Trusted
Our product has undergone public testing on a renowned beauty program, proving its ability to moisturize without causing dryness or tightness.
Gentle, Gel-type Foam Cleansing
Ideal for sensitive skin, our cleanser balances skin oil and moisture, soothes, and is suitable for all skin types, including dry and oily.

Unbeknownst to me, the SISEUNDEUSI Mildly Acidic Agar-Agar Weed Foam Cleansing became a treasure on my skincare journey! After years of wrestling with harsh products in bustling Brooklyn, stumbling upon this delicately formulated cleansing foam brought both serenity and nourishment to my once-overlooked skin. The intricate harmony derived from wild herbs merges gracefully with water-based aesthetics for a light but effective wash—just perfect for daily rituals! Although pricey compared to generic offerings here like Cetaphil or Neutrogena cleansers littering every drugstore aisle, its authenticity lies rooted in Korea’s lush herbal history that’s actually accessible even across oceans.
