SKIN LIPIDS
Description
Skin lipids are essential components of the skin's protective barrier, playing a crucial role in maintaining skin health and function. These naturally occurring fats and oils form a complex mixture that includes ceramides, cholesterol, and free fatty acids. Together, they create a waterproof seal that prevents excessive moisture loss and protects against environmental stressors.
Ceramides, the most abundant lipids in the stratum corneum, are vital for maintaining skin hydration and preventing irritation. Cholesterol contributes to the skin's flexibility and permeability, while free fatty acids help regulate pH levels and possess antimicrobial properties.
The composition of skin lipids varies among individuals and can be influenced by factors such as age, diet, and environmental conditions. Imbalances or deficiencies in skin lipids can lead to various dermatological issues, including dryness, sensitivity, and impaired barrier function.
In skincare formulations, synthetic or plant-derived lipids are often used to supplement and support the skin's natural lipid barrier. These ingredients can help improve skin hydration, reduce inflammation, and enhance overall skin health when incorporated into moisturizers, serums, and other topical products.
