A sebaceous gland or oil gland [1] ... After birth, activity of the glands decreases until there is almost no activity during ages two–six years, ...
Vernix is produced during a distinct phase of the epidermal development. [2] Around the 21st week of gestation, periderm cells are being shed and replaced with stratum corneum; these shedding mix with secretions of sebum by the sebaceous glands to form vernix, which gradually covers the body in an anteroposterior and dorsoventral pattern.
The condition is named for an overgrowth of sebaceous glands, a relatively uncommon hamartoma, in the area of the nevus. NSJ is first described by Josef Jadassohn in 1895. [5] Skin growths such as benign tumors and basal cell carcinoma can arise in sebaceous nevi, usually after puberty. Rarely, sebaceous nevi can give rise to sebaceous ...
Histologically, vellus hair follicle growth with perifollicular fibrous thickening occasionally encircled by a cellular stroma is the hallmark of hair follicle nevus. Smooth muscle fibers and eccrine and sebaceous glands are at times visible. [2]
They are sebaceous glands, which secrete sebum oil that is a free fatty acid onto the skin that lubricates the nipple when breastfeeding, protects the skin, and provides some air tightness between the infant's mouth and the nipple.

[1] Humans have three types of sweat glands: eccrine sweat glands, apocrine sweat glands and sebaceous glands. Eccrine sweat glands are present from birth ...
