Healthy skin owes its smooth, bouncy appearance to a dense network of collagen and elastin in the dermis. After age 25, collagen production declines by roughly 1% per year, and elastin fibers progressively fragment. The American Academy of Dermatology identifies this structural decline, combined with ultraviolet exposure, as the primary driver of visible aging.
As these proteins thin, the skin loses its ability to snap back from expression. Repeated contractions of the forehead, brow, and mouth muscles etch dynamic lines that eventually settle into static wrinkles visible even at rest. Treatments like Exion Face and Body and Emface target this loss by stimulating neocollagenesis and toning underlying facial structure.
Barrier function and hydration also decline with age. As transepidermal water loss rises, the skin reflects less light, and fine dehydration lines become more prominent. This is why wrinkles often appear worse in dry weather or after a poor night's sleep.
