Stratum Lucidum
The ridges in the skin at the tips of our fingers create unique patterns that form our fingerprints. These ridges are formed by the dermal papillae, which are small bumps in the top layer of the skin (epidermis).
The epidermis is highly keratinized, mostly dead, stratified squamous epithelium.
The dermal layer responsible for fingerprints is the papillary layer.stratum germinativum

The ridges on the surface of the skin, especially on the fingertips and toes, are caused by the dermal papillae—small, finger-like projections of the dermis (the inner layer of the skin) that push upward into the epidermis. These dermal papillae create unique patterns of friction ridges, which appear as the visible lines and whorls we see on the skin surface. 👉 These ridges are important because: They improve grip and traction on surfaces. They enhance sensitivity by increasing the skin’s ability to detect textures. They form the basis of fingerprints, which are unique to every individual.
The reticular layer is 80 percent of the dermis and is responsible for the tension lines in the skin. These lines are called Langer's lines and are important in surgical procedures to minimize scarring.
The upper layer of the dermis that forms dermal papillae is known as the papillary dermis. This layer is composed of loose connective tissue and contains small, finger-like projections called dermal papillae, which interdigitate with the epidermis. These structures enhance the surface area for exchange of nutrients and waste, and they contain capillaries, nerve endings, and sensory receptors, contributing to the skin's tactile functions.

The layer below the Epidermal layer is called the Dermal layer. It's a connective tissue made up of collagen and elastin.
The Papillary is the upper layer of the dermis that has ridges and valleys causing finger prints. It has receptors which communicate with the central nervous system, these include touch, pressure, hot, cold and pain receptors.
The dermal papillae are responsible for forming fingerprints. These are found in the upper layer of the dermis and create raised patterns on the skin's surface, resulting in unique fingerprint patterns for each person.
