Retention hyperkeratosis refers to the accumulation of dead skin cells in the hair follicles, which can lead to clogged pores. This condition is particularly relevant in acne vulgaris, a skin condition characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, and sometimes cysts.

In acne vulgaris, the clogged follicles can become inflamed and infected, leading to the characteristic lesions associated with this condition. The hyperkeratinization process inhibits the normal shedding of dead skin cells, which further contributes to the blockage of the pores and the development of acne lesions.

While other skin conditions mentioned may involve hyperkeratosis to a degree, the direct link between retention hyperkeratosis and acne vulgaris is particularly strong, making it the most appropriate choice in this context. Rosacea, psoriasis, and allergic dermatitis have different underlying mechanisms and are not typically driven by the same process of retention hyperkeratosis in the same way that acne is.
