Sebaceous glands secrete an oily substance called sebum. This helps protect the skin from the outside environment. Due to an overgrowth of oil-producing cells, sebum can become trapped inside the gland, causing it to swell and form a bump under the skin. This is known as sebaceous hyperplasia.
It's caused when your sebaceous oil glands produce too much oil, which can be trapped under your skin and cause bumps. The good news is, there are many treatment options available for sebaceous hyperplasia.
What Do They Look Like? Usually you can spot a blackhead easy enough, sebum plugs are a little trickier but if you grab a magnifying glass you can see them no problem. You will notice that although they may look like little black dots from a distance, they are actually more of a white or yellow color.

Refined carbohydrates like sugar, refined flour, white bread, bakery products, desserts are quickly digested and absorbed into the bloodstream, resulting in a spike in insulin levels. High insulin levels increase the level of androgens, which stimulates excessive sebum production, oily skin and acne.

High-dose red light photodynamic therapy (PDT) offers highly effective and durable treatment for acne by selectively destroying the sebaceous gland.
What Does Sebum Buildup Look Like? Sebum buildup appears as white or yellowish oily residue on the scalp. It sometimes produces flakes on the scalp and may be mistaken for dandruff, scalp eczema, or psoriasis.
Vitamin D is a fat-soluble vitamin that works alongside our sebaceous glands to regulate sebum production. Vitamin D helps our bodies protect against insulin resistance which can lead to oily skin as insulin stimulates the overproduction of sebum.
In elderly men, sebum levels remain essentially unchanged from those of younger adults until the age of 80. In women, sebaceous secretion decreases gradually after menopause and shows no significant change after the 7th decade.
Sebum melts at 30°C, and hot water washes away the protective barrier, especially on the shoulders, upper arms and back, where the impact of the shower jet is strongest. Physical exercise may have provided an additional source of irritation.
Diets higher in protein and fiber and lower in saturated fats and refined carbohydrates work well for oily and acne-prone skin. To reduce sebum production, try a Paleolithic diet (rich in fruits, veggies, nuts, and lean meats) or a Mediterranean-style diet (rich in fruits, veggies, fish, olive oil, and legumes).
The stress hormone cortisol leads to an overproduction of sebum (oil) in your skin glands, which causes acne breakouts.
Sebum production is under the control of sex hormones (androgens). The most active androgens are testosterone, 5-testosterone (DHT) and 5-androstene-317diol. These hormones and others are made by the sex glands (ovary in females, testis in males) and by the adrenal gland.
They occur when the pore's walls break down, causing a bigger pimple to form. Pustules are typically white and, unlike papules, they contain pus. A person may find that a pustule is tender to the touch.
Sebum plugs result from hormones and increased stress levels. Sebum plugs usually develop on the face, including the forehead, chin and nose. They look more like pimples and have a “head.” In fact, sebum plugs appear before zits and can turn into pimples.
