    TLDR Alpaca skin has glands, hair follicles, and different collagen types.
    This study analyzed the skin morphology of alpacas by examining biopsies stained with various techniques and assessing collagen types through immunohistochemistry. The findings revealed the presence of sebaceous and sweat glands, follicular groups with medullated fibers, and different types of collagen. Type I and IV collagen were found in the epidermis, dermis, glandular structures, and hair follicles, while Type III collagen was only present in the dermis.
