Which ethnic group is known to have a higher proportion of sebaceous glands and ages at a slower rate?

The ethnic group known to have a higher proportion of sebaceous glands, which can contribute to skin oiliness, and is often cited as aging at a slower rate is the African Caribbean group. This can be attributed to several factors including genetic and hormonal influences that affect skin characteristics.

Individuals from this background tend to have thicker dermis and epidermis layers, more active sebaceous glands, and a higher presence of melanin in the skin, which can provide some protection against the signs of aging such as wrinkles and fine lines caused by sun exposure. The enhanced oil production from the sebaceous glands may also contribute to a more youthful appearance, as natural oils help maintain skin moisture and elasticity.

In comparison, the other ethnic groups, while they may have unique skin characteristics, do not generally exhibit the same combination of sebaceous gland density and aging characteristics.
