Ceramides are lipid molecules that make up roughly 50% of the skin's barrier by composition [7]. They form the "mortar" between skin cells, creating a waterproof seal that prevents moisture loss and blocks environmental irritants. Research published in the International Journal of Cosmetic Science confirms that ceramides play a central role in skin barrier function and that their correct formulation is critical for effective skincare applications [8]. As we age, natural ceramide production declines, contributing to dryness, sensitivity, and visible signs of aging on the body [9].
Dewsy's Complete 5 Ceramides Complex includes Ceramide EOP for barrier repair, Ceramide AP for elasticity, Ceramide NP for moisture retention, and Ceramides NG and AG for barrier cohesion. Together, these five ceramides mirror the skin's natural lipid profile, which allows them to integrate seamlessly into the existing barrier structure rather than simply sitting on top of it. Studies show that topical ceramide application can measurably improve skin barrier function and hydration - a finding supported by research using Raman spectroscopy to track ceramide absorption into the stratum corneum [10].
The skin's lipid barrier works best when ceramides, cholesterol, and free fatty acids are present in balanced ratios. Landmark research has shown that the optimal ratio of these three lipid classes accelerates barrier recovery [11]. Dewsy's formulation is designed with this principle in mind, delivering a lipid profile that complements the skin's own composition.
