The granular cells are named after the keratohyalin granules that they contain, giving them a "granular" appearance. The cells in the outermost horny layer change in a number of ways. A number of organelles including nucleus disappear and the cells are filled with fibrous protein named keratin. The divided basal cells therefore move in sequence to the surface of the epidermis and their form changes as described through a continuous and complex process to produce the biologically and chemically resistant horny layer.
Additionally, there are other causal factors including genetic factors, food, overwork and stress. 2. Development and formation of acne As described in the previous section on the causes of acne, overactive secretion of sebum coupled with hyperkeratosis causes the hair pores to become narrowed and blocked, resulting in the early first stage of acne called a comedo (Fig. 12b,c). Subsequently, the comedo damages and effects the surrounding tissues resulting in inflammation of the tissues surrounding the opening of the sebaceous gland (Fig.
When the large pustule subsequently heals, granulation often occurs and a scar remains. 3.
