10 Causes of Light Red Or Pink Bumps On Skin
This list does not constitute medical advice and may not accurately represent what you have.
Non-specific dermatitis (skin inflammation)
Nonspecific dermatitis, or contact dermatitis, simply means inflammation of the skin from many different causes.
Most nonspecific dermatitis is caused by skin contact with a substance that provokes a reaction, which could be anything from plants to soap to jewelry to fabrics. Some may be due to an autoimmune condition, where the body's immune system attacks itself.
Risk factors include a family or personal history of allergies, asthma, or other condition which weakens the immune system; or constant contact with metals, plant life, or chemicals.
Symptoms commonly include red, swollen skin rash with itching, blistering, or oozing, which may become painful and infected.
Dermatitis itself is not contagious but can interfere with quality of life. A medical provider can help with managing the symptoms.
Diagnosis is made through patient history, physical examination, and sometimes skin biopsy and patch testing.
Treatment involves using protective measures if the substances cannot be avoided; making nutritional improvements to strengthen the immune system; using corticosteroid or other creams; and phototherapy.
Top Symptoms: red rash, itchy rash, painful rash
Symptoms that always occur with non-specific dermatitis (skin inflammation): red rash
Non-specific skin rash
Common causes of rash are contact dermatitis, sun damage, or allergic reaction. However, many rashes are a symptom of disease and should not be ignored.
Nonspecific rashes have widely varied symptoms:
- May be flat and smooth; slightly raised or with swollen welts; clean and dry; or blistered and oozing.
May spread widely over the body, or be confined to one site.
- May appear after eating certain foods; or after exposure to certain plants or to insect stings or bites.
Other symptoms may be present, including pain anywhere in the body; nausea; vomiting; fever; headache; or abdominal pain and upset.
Diagnosis is made through patient history and physical examination to determine the exact type, location, and history of the rash, along with any other symptoms that may be present.
Those symptoms will be investigated with blood tests or imaging. Skin swabs may be taken and tested. After the process has ruled out as many causes as possible, a course of treatment can be determined.

Irritant contact dermatitis
Irritant contact dermatitis means a skin reaction that is caused by directly touching an irritating substance, and not by an infectious agent such as a bacteria or virus.
Common causes are soap, bleach, cleaning agents, chemicals, and even water. Almost any substance can cause it with prolonged exposure. Contact dermatitis is not contagious.
Anyone who works with an irritating substance can contract the condition. Mechanics, beauticians, housekeepers, restaurant workers, and health care providers are all susceptible.
Symptoms include skin that feels swollen, stiff, and dry, and becomes cracked and blistered with painful open sores.
A medical provider can give the best advice on how to heal the skin and avoid further irritation. Self-treatment can make the problem worse if the wrong creams or ointments are used.
Diagnosis is made through patient history, to find out what substances the patient comes into contact with, and through physical examination of the damaged skin.
Treatment involves avoiding the irritating substance if possible. Otherwise, the person can use petroleum jelly on the hands underneath cotton and then rubber gloves.

Hives, or urticaria, are flat red welts that can appear anywhere on the skin and usually itch. Hives often occur as an allergic reaction to something eaten or something that has contacted the skin.

Psoriasis causes an overgrowth of surface skin cells, creating a red, scaly, itchy, and painful rash.
It is believed to be an autoimmune disorder that causes the body to attack its own healthy skin cells. It may be genetic in origin but triggered by anything that further strains the immune system, such as infections, skin injury, alcohol consumption, obesity, smoking, and stress.
Symptoms may come and go in cycles lasting weeks or months. They include red patches of thickened skin, sometimes with gray-white scales; dry, cracked, bleeding skin; stiff and swollen joints; and thickened, misshapen nails.
It is important to see a medical provider for care, because psoriasis can interfere with quality of life. It is associated with higher risk of arthritis, heart disease, diabetes, and other conditions.
Treatment involves different combinations of topical medications, oral medications, and phototherapy with natural or artificial light. Lifestyle changes such as improved diet, quitting smoking, and managing stress are very helpful in many cases.

Non-melanoma skin cancer (squamous cell carcinoma)
Squamous cells are the small, flat skin cells in the outer layer of the skin. Squamous cell carcinoma (SCC) a type of skin cancer that usually appears as a tiny, painless bump or patch. The most common spots for this cancer are the head (including scalp, lips, ears, and mouth), legs, and the backs of the hands and the arms.
Top Symptoms: rash on sun-exposed areas, rash with well-defined border, painful rash, light red or pink bump on skin, scaly rash

Symptoms that never occur with non-melanoma skin cancer (squamous cell carcinoma): fever

Non-specific insect bite
Insect bites are very common. The saliva given off during the bit can sometimes cause dangerous allergic reactions that affect your ability to breathe. However, the vast majority of insect bites have no adverse effects besides the inflammation where the bite occurred.
Pimples are also called comedones, spots, blemishes, or "zits." Medically, they are small skin eruptions filled with oil, dead skin cells, and bacteria.
Pimples often first start appearing at puberty, when hormones increase the production of oil in the skin and sometimes clog the pores.
Most susceptible are teenagers from about ages 13 to 17.
Symptoms include blocked pores that may appear flat and black on the surface, because the oil darkens when exposed to the air; blocked pores that appear white on the surface because they have closed over with dead skin cells; or swollen, yellow-white, pus-filled blisters surrounded by reddened skin.
Outbreaks of pimples on the skin can interfere with quality of life, making the person self-conscious about their appearance and causing pain and discomfort in the skin. A medical provider can help to manage the condition, sometimes through referral to a dermatologist.
Diagnosis is made through physical examination.
Treatment involves improving diet; keeping the skin, hair, washcloths, and towels very clean; and using over-the-counter acne remedies.
Top Symptoms: pink or red facial bump, small facial lump, painful facial bump, marble sized facial lump
Symptoms that always occur with pimple: pink or red facial bump
