N-STEAROYL-DIHYDROSPHINGOSINE

Description

N-Stearoyl-dihydrosphingosine is a synthetic ceramide that plays a crucial role in maintaining skin barrier function and hydration. This lipid molecule mimics naturally occurring ceramides found in the skin's stratum corneum, the outermost layer of the epidermis. By incorporating N-stearoyl-dihydrosphingosine into skincare formulations, products can help replenish and support the skin's protective barrier.

This ingredient is particularly beneficial for individuals with dry, sensitive, or compromised skin. It helps to reduce transepidermal water loss (TEWL), thereby improving skin hydration and elasticity. N-stearoyl-dihydrosphingosine also aids in protecting the skin from environmental stressors and irritants by strengthening the barrier function.

In skincare formulations, N-stearoyl-dihydrosphingosine is often combined with other ceramides, fatty acids, and cholesterol to create a balanced lipid profile that closely resembles the skin's natural composition. This ingredient is typically used in concentrations ranging from 0.1% to 2% in leave-on products such as moisturizers, serums, and barrier repair creams. Its inclusion in skincare products can contribute to improved skin texture, reduced inflammation, and enhanced overall skin health.
