Friction is thought to play a role in their development, although the exact cause is not fully understood. Skin tags are also associated with factors such as increasing age, pregnancy, and metabolic conditions, including insulin resistance.
However, having skin tags does not automatically mean someone has diabetes or another metabolic disorder. If many new skin tags appear, particularly alongside other health concerns, discussing them with a healthcare professional may be worthwhile.
Skin tags are not caused simply by sleeping on a particular side or failing to wash properly. If one becomes irritated by clothing or jewelry, a clinician can advise whether removal is appropriate.
Do not cut skin tags off with scissors or tie them tightly at home. What appears to be a skin tag may be another type of growth, and attempting removal can cause bleeding, infection, and scarring.
Warts: Growths associated with a virus
Warts are caused by certain types of human papillomavirus. They can appear as rough, firm, or occasionally smooth raised growths, depending on their location and type.
Common warts often occur on the hands and fingers, while other varieties may appear on the feet or elsewhere on the body. Some warts occur in groups, which can make the affected area look more extensive.
Unlike ordinary skin tags, warts can spread through direct contact or contaminated surfaces, depending on the type and circumstances. Picking or scratching them may also contribute to spreading the virus to nearby skin.
A wart may resemble other benign growths, and not every raised lesion is a wart. If you are uncertain about a bump, especially one that bleeds or changes, have it assessed before attempting treatment.
Over-the-counter wart treatments are not suitable for every location. Products intended for ordinary hand or foot warts should not be applied to the face, genitals, or other sensitive areas without appropriate medical advice.
Seborrheic keratoses: Common benign growths
Seborrheic keratoses are common noncancerous skin growths that become more frequent with age. They may look waxy, rough, scaly, or as though they are sitting on top of the skin.
Their color ranges from light tan to brown or nearly black. Some are flat, while others become quite raised.
They may appear on the chest, back, face, or other areas of the body. Multiple lesions can develop over time, and their appearance sometimes causes concern because they resemble other skin conditions.
Although seborrheic keratoses are usually benign, an unfamiliar or changing lesion should not automatically be assumed to belong to this category. A clinician can assess whether it has the characteristic appearance or needs further investigation.
Keloids: When scar tissue grows beyond the original injury
Keloids are raised scars that extend beyond the boundaries of the original wound. They can develop after cuts, burns, surgery, acne, piercings, or other skin injuries.
Unlike many small benign growths, keloids involve an exaggerated scar-forming response. They may continue growing beyond the original injury and can cause itching, tenderness, or discomfort.
Keloids may be pink, reddish, brown, or darker than the surrounding skin. Some people are more prone to developing them because of genetic and individual factors.
Sleeping on a particular surface does not ordinarily cause a keloid to develop from otherwise healthy skin. However, pressure or friction may irritate an existing scar.
Treatment options vary and may include silicone-based products, corticosteroid injections, or other approaches recommended by a dermatologist. Treatment can be challenging, and some keloids return after removal.
Cysts and other lumps beneath the skin
Some skin lumps originate beneath the surface rather than growing outward from it. Epidermoid cysts, for example, can appear as rounded lumps under the skin and may remain stable for a long time.
A cyst can become inflamed, swollen, tender, or infected. It may sometimes release material through a small opening, but squeezing it can worsen inflammation and increase the risk of complications.
Other lumps may arise from fatty tissue, connective tissue, or different structures within the skin. Their causes and treatment requirements vary.
A new lump that feels deep, grows rapidly, becomes painful, or appears fixed to surrounding tissue deserves medical assessment. The same is true of a lump associated with fever, spreading redness, or drainage.
Why similar-looking bumps may need different treatments
Two lesions that appear almost identical in a photograph may require completely different care. A skin tag, wart, cyst, and scar do not share the same underlying cause, so treating them as though they were interchangeable can be ineffective or harmful.
A dermatologist may consider the patient's age, medical history, medications, family history, and the timeline of the growths. A visual examination may be sufficient, but a biopsy or other test can sometimes be necessary.
The safest approach is to avoid diagnosing yourself from a dramatic photograph or online description.
The key lesson: multiple raised bumps do not automatically indicate a serious disease, but their appearance alone cannot establish that they are harmless. Identifying the cause is the first step toward choosing the right treatment.
Chapter 3: Can Poor Sleep, Friction, or Hygiene Make Skin Bumps Worse?
Sleep gives the body time to recover from daily demands, and the skin continues to perform important maintenance functions during the night. Yet headlines suggesting that sleeping in a certain way causes dramatic skin growths can create unnecessary fear.
The relationship between sleep, skin health, and raised lesions is more complicated. Some nighttime conditions can aggravate existing skin problems, while many growths develop for reasons unrelated to bedding or personal hygiene.
Understanding the difference can help you care for your skin without blaming yourself for changes that may have little to do with your habits.
