What Causes Acne? – Part 1 – Part 2

Although getting pimples on the face is hard to deal with, the condition also affects other parts of the body. For instance, you can get acne on the back and legs, as well as on your buttocks.

On the face, the jawline and the chin, as well as the nose are particularly susceptible to the condition. This is even more so for teens and young adults. Some of the causes of acne on these body parts include hormonal imbalances.

Hormones are responsible for stimulating the production of oil by the body. When there are shifts in how hormones work, there will be an increase in the bacteria trapped in the skin’s pores. This often leads to sore and painful cystic blemishes and pustules.

Understanding what causes pimples will improve your knowledge of the condition, as well as make it easier for you to know what to do to deal with them.

Why Do I Have Pimples on the Tongue?

Have you experienced pimples on your tongue? Find out why and what to do about them.

Painful acne on the tongue is often referred to as a lie bump. However, medics call these types of tongue pimples transient lingual papillitis. The acne will often look white or red – although the color will mostly depend on what caused the pimples to appear in the first place.

In most cases, you will find painful bumps on your tongue due to an inflammation or irritation of the fungiform papillae. This is the area on the tongue where the taste buds are located.

That said, tongue pimples are common both in adults and children, and are caused by:

A: Allergies

Pimples on the tongue might be caused by food allergies. Certain lip and mouth care products, medications, and food can cause an allergic reaction. The result might be that your immune system will respond by creating tongue acne.

B: Tongue Trauma or Injuries

On the other hand, accidental or deliberate tongue trauma or injuries might be responsible for the pimples you have on your tongue. These include tongue piercings, dental appliances like braces, eating tough or hard food, and biting your tongue.

Tongue injuries and trauma will irritate or bruise the tongue and cause painful bumps – particularly on the side or tip. As they start healing, these pimples will look white in color.

C: Oral Thrush

Otherwise referred to as Oral Candida, oral thrush is a fungal infection. It creates red pimples as a natural reaction when the taste buds get irritated. When you get oral thrush, you may develop red acne on the back, tip, and/or sides of the tongue.

D: STDs or Viral Infections

There are tons of viral infections that may cause white pimples on your tongue, as well as on the lips and other parts of your mouth. These infections include but are not limited to oral herpes, cold sores, and flue.

Pimples on the tongue caused by oral herpes usually ooze clear pus-like liquids. You may also get other symptoms related to the flue, including weakness, fatigue, dry coughs, sore throat, and fever.

E: Canker Sores

Otherwise referred to as mouth ulcers, canker sores are small lesions that tend to develop right on mouth tissue or at the base of your gums. They look like pimples and will make it difficult for you to eat or talk.

Some of the causes of tongue cankers include hormonal changes, viral infections, nutritional deficiencies, stress, and food allergies.

F: Oral Cancer

Oral cancer might cause stubborn and swollen but frequent tongue pimples. Other symptoms of oral cancer include difficulty chewing or swallowing, ear pain, dramatic weight loss, and unexplained numbness and bleeding in the mouth.

G: Kawasaki Disease

Scientifically referred to as mucocutaneous lymph node syndrome, Kawasaki disease tends to produce large and red bumps at the back of your tongue. Apart from the bumps, the disease might also affect the skin, the mouth’s mucous membranes, and lymph nodes.

Other symptoms of this disease include redness of the soles and palms, fever, joint pains, cracked lips, vomiting, diarrhea, abdominal pain, and bloodshot eyes.

H: Leukoplakia

Leukoplakia causes thick white pimples or patches on the tongue, as well as on the bottom of the mouth, and inside the cheeks. Smoking or chewing tobacco is one of the causes of this disease, and some of the patches might be an early sign/symptom of cancer.

Leukoplakia mostly affects people with weak immune systems due to such conditions as HIV/AIDS as well as taking certain medications.

Leukoplakia Defined

Leukoplakia is a whitish plaque or patch that cannot be pathologically or clinically characterized as any other disease; it is not associated with any chemical or physical causative agent apart from tobacco use

I: Hairy Black Tongue

When yeast and bacteria build up on the tongue, they may cause hairy black tongue. The condition often comes with yellow, white, or black discolorations. Other symptoms may include a hairy appearance on your tongue, a gagging or tickling sensation inside the mouth, a metallic taste in your mouth, and bad breath.

J: Oral Lichen Planus

Oral lichen planus is a common inflammatory condition that tends to affect the mouth’s mucous membranes. It also creates red and white patches on the tongue. The lesions may also occur inside the cheeks, on the lips’ inner tissues, and on the gums.

Some of the causes of oral lichen planus include allergies to dental products, mouth injuries, infections, and certain medications.

Why Do I Have Pimples on My Chin?

Find out the truth about why you have pimples on your chin and how to be rid of their annoyance.

Chin acne often appears in the form of big painful pimples that keep popping up repeatedly. These pimples can multiply all along the jawline.

Some of the causes of these types of pimples include:

A: Poor Diet

For starters, chin acne might be caused by food allergies or a poor diet.

If you are allergic to certain foods and you do not balance your diet, you may suffer from these spots on the chin.  This will happen because the pimples are linked to small intestine disturbances, particularly those caused by an unhealthy diet or food allergies.

B: Hormonal Imbalance

Your chin pimples may also be as a result of hormonal imbalance, particularly during puberty, pregnancy, menstrual cycles, and menopause. For instance, you might be susceptible to these breakouts right before you get your period and the acne will disappear at the end of your menstrual flow.

C: Polycystic Ovarian Syndrome

Polycystic Ovarian Syndrome causes an imbalance in sex hormones – and an increase in the levels of androgen. This may cause your ovulation to stop and lead to the appearance of extra hair on the body and face as well as pimples.

D: Poor Lymphatic Drainage

Poor lymphatic drainage means that your body is unable to eliminate toxic substances, which collect and cause pimples to appear on your chin.

E: Stress

Pimples on the chin tend to worsen with stress and anxiety. This might be because of the existence of stress receptors on sebum-producing cells.  Therefore, if you feel stress, you may increase your risk of developing acne on the chin, which can range from the severe to the mild depending on how anxious you feel.

F: Makeup

Glosses, lip balms, and oily lipsticks may contain ingredients that will promote the growth of acne on your chin.

G: Poor Personal Hygiene

If you don’t pay attention to your personal hygiene, the chances are quite high that you will get pimples on your chin. This may happen when you:

How to Improve your Personal Hygiene

Never do the following:

  • Touch your chin or face with dirty hands
  • Touch your neck and chin with dirty mobile phones
  • Use dirty musical instruments, such as mouth organs, the tuba, and flutes
  • Use substandard and oily makeup products
H: Miscellaneous

Other things that may cause pimples to appear on your chin include:

  • A poor diet, particularly one with foods that are low on the glycemic index or those that cause inflammation
  • Boils
  • Cellulitis
  • Contact dermatitis
  • Diseases like perioral dermatitis, actinic keratosis, melanoma, moles, boils, cold sores, insect bites, abscess, facial ringworms, warts, discoid lupus erythematosus, and rosacea
  • Excessive sweating
  • Folliculitis
  • Smoking
  • Stopping using birth control pills

From poor diet and stress to makeup and hormonal imbalance, there are many reasons why you may get pimples/acne on your chin. Check each of these causes and you may be able to treat or even prevent these breakouts.

Why Do I Have Pimples on the Neck?

Neck pimples are annoying, embarrassing and painful. Find out why they exist and what you can do about them starting today.

Acne occurs when the pores of the skin are clogged with the P. acne bacteria, sebum (oil), and dead skin cells. It may appear on the neck due to the following reasons:

A: Hormonal Issues

Androgen hormones tend to increase when you reach puberty. These hormones may stimulate the enlarging of the sebaceous glands and the production of more sebum. This will cause the skin pores to clog with sebum and lead to pimples on your neck.

The issue is also common among pregnant women and those who use oral contraceptives regularly.

B: Stress

College students tend to experience acne flare-ups when exams approach or as they are underway. This may be due to an increase in stress.

C: Shaving

Making the wrong choice of shaving tools, cosmetics, and aftershave products may cause ingrown hairs to create itchy pimple-like bumps particularly on the front side of the neck. The pimples may also be caused by shaving before washing the hands or using equipment that is dirty.

D: Makeup and Cosmetics

Makeup and cosmetics also cause or worsen zits particularly on the neck. This is especially so if you use oily products that will clog your pores or if your makeup remains on for a longer time than it should.

E: Diet

Certain dietary factors, such as eating carbohydrate-rich foods and dairy products, may also trigger neck acne.

F: Others

Some of the other reasons why you may get pimples on the neck include, but are not limited to:

  • Failing to wash your neck properly and regularly, particularly after sweating
  • Using products that may block the sebum on your skin, including hair products, sunscreens, and moisturizers
  • Wearing equipment and clothing that rubs the neck
  • When long hair rubs against the neck

As long as you are able to keep the above causes in check, it shouldn’t be too hard for you to get rid of pimples on your neck. Of course, you can also count on other remedies to help along with the treatment/prevention.

Why Do I Have Pimples on the Chest and Back?

Understanding the reason for pimples on your chest and back as well as what to do about them.

Pimples do not just crop up on the face. They also occur on the back and face – especially among those who already suffer from facial acne. This is because the skin on the chest and back is thicker and it has larger pores, which is why this type of acne tends to be more severe.

Some of the other causes of pimples on the back and chest include:

A: Sweat

When you sweat from overexertion or exercising, the sweat may bead on the skin and mix with the toxins and oils on the surface of the skin. If you leave the sweat there, it will irritate and clog the pores, resulting in chest and back acne. Therefore, you should shower immediately after you sweat excessively to wash off the toxins and sweat.

B: Clothing

Wearing tight-fitting clothing, particularly that made of a material that will not allow the skin to breathe properly may irritate your skin and result in chest and back acne. The best way to deal with this problem is to get loose-fitting clothing in breathable fabric. You should also wash your skin thoroughly with mild soap to prevent these pimples.

C: Acne Mechanica

This is a type of acne that is mostly caused by irritations found on the chest and back. It occurs when something rubs against the skin – such as weightlifting machines and backpacks, as well as over-the-shoulder strap bags.

D: Sheets

Sheets and other materials that come into constant contact with the skin tend to absorb dirt and oils from your skin. These will build up over time and provide the ideal breeding ground for acne-causing bacteria. Wash your blankets, duvets, and sheets at least once every week to deal with this condition.


The chest and the back are body parts that are commonly affected by acne. Always ensure that you deal with the above causes of pimples to ensure that you do not have to deal with breakouts every few months.

Why Do I Have Pimples on My Thighs and Buttocks?

Though they are normally hidden parts of the body, pimples on your thighs or butt are uncomfortably annoying. Learn what to do should this happen to you.

Acne on the thighs and buttocks is caused by a variety of factors, including but not limited to hormones, gaining weight, and others. This area of the body is normally covered.  Therefore, it is not surprising that it is so susceptible to pimples.

Consider the following common causes of thigh and buttocks pimples:

A: Shaving

The small and itchy bumps on your thighs may be as a result of razor bumps and burns. Bad waxing bikinis and poor shaving techniques tend to cause bumps that are itchy and which can hurt when you walk.

B: Thighs Rubbing Together

This condition is also referred to as thigh chafing. It occurs when the skin on the thighs rubs together – particularly in people who have recently gained weight. It also happens while exercising, swimming, and running. The symptoms of the condition include flaky little bumps, red skin, irritation and burning sensations on the inner thighs, as well as dark inner thighs.

If you have boils, bumps, zits, or pimples on the inner thighs, they will be worsened by thigh chaffing and be bleeding, hurt a lot, and/or become red or pink.


Pimples, warts, and sores are some of the signs of an STD on the genitals. In particular, if you have HPV, you may get genital warts and confuse them for acne-like bumps. They mostly appear as fleshy lumps or growths on the skin in between the thighs.

STDs also cause blisters that look like pimples on the inner thighs which tend to spread to other areas of the body and become itchy. If you pop, pick, or scratch these zits, they may spread, transmit to other areas of your body, or even start bleeding.

D: Hormonal Acne

Pimples and other skin breakouts are common during periods, pregnancy, and puberty. This is due to the hormonal change that occurs during these periods. This happens because the oil glands in the skin tend to become hyperactive and produce excess sebum or oil. The sebum then clogs the skin’s pores and causes a breakout of acne on the buttocks, inner legs, and thighs.

E: Keratosis Pilaris

In case you have scaly patches or pimples on the upper part of your inner thigh, it might be a sign of keratosis pilaris. This common skin condition tends to leave acne-like bumps and zits, as well as rough patches, on these body parts. It also common on the upper legs, buttocks, and arms.

Other symptoms of keratosis pilaris include:

  • Non-itchy bumps and pimples on the skin
  • Rough and dry skin that looks like patches
  • Small white spots resembling whiteheads
  • Turning pink or red when inflamed and irritated
  • White pimples on the thigh that worsen in winter due to low humidity
F: Sweat

Sweat bumps and pimples are likely to appear on the upper side of the inner thighs, in the groin area, and around the buttocks. Most people report these itchy zits particularly after exercising.

The sweat will cause bacteria to thrive fast. In turn, this will encourage such conditions as infected thigh and butt pimples, inflammation, and folliculitis, as well as fungal infections.

G: Heat Rash

Wearing tight jeans may also cause pimples to appear on the thighs and buttocks. If you wear skin-tight jeans, therefore, you should not be surprised when you get acne, pimples, blackheads, and rashes on these body parts.

This is because the clothing tends to irritate the hair follicles around the butt and thighs. This results in pimples appearing on the legs, bum, and even around the waist or stomach.

H: Weight Gain

Weight gain is another one of the major causes of acne on the buttocks and inner thigh region. When the thighs rub together, they will cause friction which can, in its turn, create bumps and roughen the skin. Over time, the skin will become dark and develop scars. These are particularly embarrassing when you have to wear a swimming outfit or bikini.

How to Tone Your Thighs Like a Boss

The following are some exercise tips that can help you prevent bumps by toning your thighs:

  1. Cossack squats
  2. Lower stance squats
  3. Plie squats
  4. Squatting while holding a ball in between the thighs
  5. Sumo squats

If you are able to keep your legs, thighs, and buttocks in good health, you should not have to worry about pimples appearing in these body parts. If you already have this type of acne, get natural remedies to help go away.

How do You Get Rid of Pimples? – Concluded

As a common skin disorder, acne affects people of all ages and socio-economic backgrounds. Every year, for instance, more than 50 million Americans have to deal with the condition in different body parts and degrees. The American Academy of Dermatology reports that acne happens to be the most common skin problem in the country.

Acne happens when the skin’s pores become blocked with bacteria, dead skin cells, and oil. The pores of the skin will open up to follicles under the epidermis. In these follicles are sebaceous glands and hairs. The glands produce sebum, the oil that keeps the skin soft and lubricated.

However, when factors such as hormonal changes cause these glands to produce sebum in excess, the oil gets pumped right through the follicle. In the process, it may pick up P. acne bacteria and dead skin cells on the way out.

When these substances get clumped together, they will form a plug. The plug will then press against the skin surface and your body will respond by accumulating white and red blood cells to combat any potential infection. This will cause redness and inflammation.

Overall, pimples tend to occur on the buttocks, arms, thighs, chest, tongue, face, neck, and back, as well as on many other areas of the skin. Therefore, you should understand what causes the pimples to appear to know what you should do to deal with them.
