ARACHIDONIC ACID

Description

Arachidonic Acid (AA) is a polyunsaturated omega-6 fatty acid that plays a crucial role in skin health and function. Naturally present in cell membranes, AA is a key component in the production of eicosanoids, which are signaling molecules involved in inflammation and immune responses. In skincare formulations, AA is valued for its ability to support the skin barrier function and enhance moisture retention.

This essential fatty acid contributes to the skin's natural lipid barrier, helping to prevent transepidermal water loss and maintain skin hydration. AA also plays a role in cell signaling and regulation, influencing processes such as cell growth, differentiation, and wound healing. When applied topically, it can help improve skin elasticity and firmness.

However, AA's pro-inflammatory properties require careful consideration in formulations. While controlled inflammation can stimulate collagen production and skin renewal, excessive levels may exacerbate certain skin conditions. Skincare products containing AA are often formulated with complementary ingredients to balance its effects and maximize benefits. Proper concentration and delivery systems are crucial for optimal efficacy and skin tolerance.
