Characteristics of Oily Skin
Oily skin is primarily characterized by increased sebum production, which leads to a shiny appearance, especially on the forehead and sides of the nose. This type of skin tends to have dilated pores and is often prone to blackheads.
Oily skin is typically thicker compared to other skin types, which allows it to stay youthful for longer, as it is less prone to sagging and fine lines. However, when wrinkles do appear, they tend to be deeper and harder to treat compared to the fine lines found in dry skin.
The pH level of oily skin is generally more alkaline, which, combined with the excess oil on the surface, creates an environment conducive to the growth of bacteria. As a result, oily skin is more susceptible to infections, particularly if a person has the habit of picking at blackheads or pimples.
