Usnea Longissima/Aquilaria Agallocha Stem Extract is a unique blend derived from two distinct plants: Usnea longissima, commonly known as Old Man’s Beard, and Aquilaria agallocha, often referred to as Agarwood. Usnea longissima belongs to the Parmeliaceae family, while Aquilaria agallocha is part of the Thymelaeaceae family.
Historically, both Usnea longissima and Aquilaria agallocha have been valued for their medicinal and aromatic properties. Usnea longissima has been used in traditional medicine for its antimicrobial and anti-inflammatory properties, while Aquilaria agallocha has been prized for its fragrant resin, often used in incense and perfumes. The journey of these plants into the cosmetic industry is relatively recent, driven by the growing demand for natural and multifunctional ingredients.
The extraction process typically involves harvesting the whole Usnea longissima plant and the stems of Aquilaria agallocha. These plant materials are then subjected to a series of processes, including drying, grinding, and solvent extraction, to isolate the beneficial compounds. The resulting extract is rich in bioactive compounds such as usnic acid from Usnea and various sesquiterpenes from Aquilaria, which contribute to its humectant and skin conditioning properties.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Usnea Longissima/Aquilaria Agallocha Stem Extract:
One of the primary benefits of Usnea Longissima/Aquilaria Agallocha Stem Extract is its role as a humectant. In simple terms, a humectant is a substance that helps to retain moisture. When applied to the skin, this ingredient attracts water from the surrounding environment and binds it to the skin. This can be particularly beneficial for those with dry or dehydrated skin, as it helps to keep the skin hydrated, plump, and smooth. By maintaining moisture levels, it can also enhance the overall texture and appearance of the skin, making it look healthier and more radiant.
Another significant benefit of Usnea Longissima/Aquilaria Agallocha Stem Extract is its skin conditioning properties. Skin conditioning agents are ingredients that help to maintain the skin’s softness, smoothness, and overall health. This extract works by forming a protective barrier on the skin’s surface, which helps to lock in moisture and prevent the skin from becoming dry and rough. Additionally, it can soothe and calm irritated skin, making it a valuable ingredient for those with sensitive skin types. By improving the skin’s condition, it can contribute to a more youthful and vibrant appearance.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
