The dermo-epidermal junction (DEJ) is a vital structure connecting the epidermis and dermis, ensuring skin integrity and facilitating nutrient exchange, oxygen, and signaling molecules between these two layers. As skin ages, the DEJ flattens and weakens, leading to wrinkles, reduced elasticity, and slower repair processes due to the breakdown of proteins like collagen and laminins. Maintaining the DEJ is key to youthful skin and can be supported through skincare ingredients.

Through the development of ex vivo normal or JDE-altered human skin models, the Syntivia team assesses the protective and restorative effects of the ingredients.
