in which layer of the dermis that has densely packed collagen are the blood vessels of the skin located?
reticular dermis
the papillary region is composed of loose areolar connective tissue. this is named for its fingerlike projections called "papillae", that extend toward the epidermis and contain either terminal networks of blood capillaries or tactile meissner's corpuscles.

the reticular dermis is the lower layer of the dermis, found under the papillary dermis, composed of dense irregular connective tissue featuring densely packed collagen fibers. it is the primary location of dermal elastic fibers.

any injury does not become a scar until the wound has completely healed; this can take many months, or years in the worst pathological cases, such as keloids. to begin to patch the damage, a clot is created; the clot is the beginning process that results in a provisional matrix. in the process, the first layer is a provisional matrix and is not scar. over time, the wounded body tissue then overexpresses collagen inside the provisional matrix to create a collagen matrix. this collagen overexpression continues and crosslinks the fiber arrangement inside the collagen matrix, making the collagen dense. this densely packed collagen, morphing into an inelastic whitish collagen scar wall, blocks off cell communication and regeneration; as a result, the new tissue generated will have a different texture and quality than the surrounding unwounded tissue. this prolonged collagen-producing process results in a fortuna scar.
