C16 Ceramide (d18:1/16:0) is widely used in skincare and cosmetic products due to its ability to strengthen the skin barrier and retain moisture. It helps repair damaged skin, reduces dryness, and improves skin elasticity, making it a key ingredient in anti-aging formulations. Additionally, it is utilized in dermatological treatments to address conditions like eczema and psoriasis by restoring the skin’s natural lipid balance. Its role in cellular signaling also makes it valuable in research focused on understanding apoptosis and cellular stress responses.
