Fine wrinkling

Fine wrinkling refers to superficial, shallow cutaneous creases—typically defined as less than one millimeter in depth and width—that affect the integumentary system, most prominently on sun-exposed regions of the face and neck Clinically, these changes manifest as a loss of tensile strength, diminished structural elasticity, and fine epidermal crinkling, distinct from the deeper dermal folds characteristic of coarse rhytids

It develops primarily in adults experiencing chronological cutaneous senescence compounded by extrinsic photoaging from cumulative ultraviolet radiation Pathophysiologically, the condition is driven by epidermal thinning, decreased glycosaminoglycan synthesis, and progressive degradation and fragmentation of dermal collagen and elastic fibers
