Hyperkeratosis

[Guide]

"Hyperkeratosis is thickening of the stratum corneum (the outermost layer of the epidermis), often associated with the presence of an abnormal quantity of keratin, and also usually accompanied by an increase in the granular layer. As the corneum layer normally varies greatly in thickness in different sites, some experience is needed to assess minor degrees of hyperkeratosis." Wikipedia

There is a thread at RF about this worth reading. 

While hyperkeratosis doesn't mimic rosacea, it can be a co-existing condition with rosacea. Keratosis pilaris is a rosacea mimic. 

Hyperkeratosis "can be treated with urea-containing creams, which dissolve the intercellular matrix of the cells of the stratum corneum, promoting desquamation of scaly skin, eventually resulting in softening of hyperkeratotic areas." Wikipedia
