Which skin type is prone to hypokeratosis?

Hypokeratosis is a condition characterized by a thinner stratum corneum, which is the outermost layer of the skin. This condition is more often associated with individuals who have darker skin types, as these skin types naturally produce more melanin, which provides some protection against environmental factors and influences skin thickness.

When considering skin types classified by the Fitzpatrick scale, Type 5 (V) and Type 6 (VI) represent darker skin tones that are indeed more predisposed to conditions like hypokeratosis. These skin types can have an increased propensity for hypopigmentation, leading to a reduction in keratin production, which can result in the skin appearing thinner or less protected.

Conversely, lighter skin types such as Type 1 (I) and Type 2 (II) generally have a thicker stratum corneum, offering more resilience against factors that can cause hypokeratosis. Type 3 (III) sits in between but still does not exhibit the same higher prevalence of hypokeratosis as Types 5 and 6 due to less melanin production and a more robust keratin layer compared to darker skin types.

Hence, the understanding of skin types and their characteristics is crucial for recognizing conditions
