What is a possible effect of hyperkeratinisation on the skin?

The formation of comedones is a significant effect of hyperkeratinization on the skin. Hyperkeratinization occurs when there is an excessive buildup of keratin, a protein essential for skin structure, on the outer layer of the skin. This thickening can lead to clogged pores, as dead skin cells do not shed properly and accumulate. When these clogged pores become blocked with excess keratin and sebum, they can form comedones, which can present as blackheads or whiteheads.

In this context, understanding the impact of hyperkeratinization is crucial because it emphasizes the importance of proper exfoliation and skincare practices to manage skin conditions effectively and prevent acne formation. The other options are not accurate because increased moisture retention, reduced blood flow, and improved elasticity do not directly relate to the effects of hyperkeratinization. Rather, they describe different aspects of skin health and function that are not typically associated with this condition.
