Blemishes are discolored marks or areas of skin. They appear in various colors and may be flat or raised. There are many different types of blemishes, each with a different causative factor. The treatment of each type of blemish differs a little. This article takes a detailed look at different forms of blemishes, their causes, treatments with medicines and home remedies, prevention and FAQs.
Common types of blemishes include uneven skin tone, acne, birthmarks, scars, age spots.
Pustules, pimples, whiteheads and blackheads can also be called categories of blemishes caused by clogged pores.
Blemishes have an unsightly appearance and can affect any area of the body but mostly appear on face, neck and shoulders.
Appearance of those discolored marks on skin can be attributed to factors such as hormonal irregularities, improper skin care, genetics, sun exposure and aging.
Here is a detailed description of different forms of blemishes:
Acne is one the most common conditions that cause blemishes. Acne can cause raised pustules or pimples and flat whiteheads and blackheads (1). When a hair follicle gets blocked due to excessive secretion of sebum by skin glands and dirt and bacteria, there is a breakout of acne.
In most people, there is breakout of acne at the onset of puberty due to hormonal changes.
Persistent acne may result in blemishes.
This is what acne looks like:
Skin care products such as medicated creams and lotions and cleansers can reduce secretion of sebum, alleviate inflammation, and unclog pores in case of mild or moderate acne.
People with severe acne may require prescription of acne medication to control hormonal imbalance.
Scarring is another major cause of blemishes. Scars are caused by excessive collagen accumulation after an injury (2).
They range widely in size, texture, and color.
Even though most scars resolve on their own, chemical peels, skin oils, products containing vitamin C and dermabrasion can help the skin heal quickly (3). Keloid scars are an exception; they continue to expand even after the skin has healed, and don’t respond well to therapy.
Cryosurgery and corticosteroid injections have proved helpful in this regard (4).
Blemishes are flat patches of discolored patches that are present at birth or appear when a person is very young. These kinds of blemishes are called birthmarks (5).
They vary greatly in size and are usually brown or black.
Moles are brown or black and port wine stains and stork bites are red.
They are mostly benign and arecaused by hyper pigmentation in one area of skin or by blood vessels being located too close to the skin. As they are generally just a cosmetic problem, they can easily be treated with laser therapy or steroids.
Some common types of birthmarks include (5):
An uneven skin tone with blotches over the face is also a type of blemish. It is caused by over production of melanin pigment (hyper pigmentation). As melanin secretion depends on hormones, sun exposure and skin injury, an excess of any of these things can cause uneven skin tone.
Treatment depends on the type of discoloration and the causative factor. Uneven skin tone is usually treated by topical creams, exfoliation, and medication to regulate hormones (6).
"Liver spots" (solar lentiginosis) are also known as lentigos.
These sun-induced pigmented lesions are brownish flat spots on the skin.
They have nothing to do with liver function. They are, in fact, signs of aging (7).
The hyper pigmentation may be triggered by over exposure to sun or exposure to ultraviolet light or other unknown causes. They are most visible on the hands and face and tend to increase in size and darken over time.
The severity and extent of liver spots are determined by sun exposure, skin type, and age.
Liver spots are mostly benign, but can easily be confused with lentigo maligna, which is an early sign of skin cancer.
Many people do not opt for a treatment of liver spots because they are an inevitable result of aging, although in some individual their appearance causes a lot of distress.
Treatment options may include the following:
Blemishes due to purpura appear when small capillaries break and blood leaks under the skin (8). In older people, purpura occurs due to the fragility of blood vessels. The blood vessels appear as red purplish flat patches. When these patches are smaller than 3 mm, they are called petechiae. When they are larger than 3 mm, they are known as ecchymoses. Patients usually have a rash at first, which eventually changes to brownish color or purplish red color. Even there is no fixed treatment for purpura, patients are advised to prevent any kind of trauma to the skin, such as forceful rubbing of the skin, which may harm the blood vessels. Emollient creams that soften the skin are also helpful in this regard. Some doctors also recommend the use of vitamin C supplements.
This skin condition is commonly observed in older adults (9). Its cause is yet to be determined. They are most conspicuous in the neck, head or trunk and may in size from 0.2 - 3 cm. Their shape is well defined and they appear to be glued onto the skin. Their appearance varies greatly:
Seborrheic keratoses are sometimes confused with melanoma when these blemishes have an irregular border. They are always benign. A skin specialist can tell the difference between the two, even though dermatologists warn that melanomas may be present under these benign blemishes and go unnoticed without careful inspection.
Mostly, seborrheic keratoses have a well-defined appearance, whereas melanomas usually have a smooth surface that differs in shape, height, size and color density. In some people, keratoses may cause discomfort and itching.
Seborrheic keratoses can be removed by surgery or by freezing. Vitamin D3 ointment is also known to be effective.
The majority of cases of skin discoloration are a result of trauma, injury, and inflammatory disorders (10). Discolored skin patches also appear due to the difference in melanin levels across different parts of the body. Melanin is the pigment that gives skin its color and protects it from harmful sunrays. If there is over production in any area of skin, that patch of skin becomes discolored.
There are many possible reasons behind blemishes caused by discolored skin patches. These may be minor problems or serious medical conditions.
Skin cancer can alter the skin’s texture and color and cause blemishes. Skin cancer develops when the structure of skin cells is damaged due to long- term exposure to sun or harmful chemicals. There is an uncontrolled multiplication of skin cells. There are many types of skin cancer and all require medical attention. Mostly, discolored skin patches and blemishes aren’t a symptom of skin cancer. But still, you should consult your doctor and ask him to examine any irregular moles or other abnormal changes in the skin.
There are many different factors that contribute towards the appearance of blemishes. Most commonly they are caused by irregular hormonal activity. Raised levels of some hormones such as estrogen can over stimulate the skin sebaceous glands, causing them to secrete extra amounts of sebum. A mixture of sebum, dirt, germs and dead cells clogs up skin pores and causes development of blemishes such as pimples, pustules, blackheads, and whiteheads. There are other causative factors too besides hormonal imbalance.
Some of the most common factors that cause blemishes are:
As we age, our body goes through many changes and unfortunately, not all of them are good.
As the health of certain organs is adversely affected, the skin also undergoes changes. Visible symptoms of aging may be evident as discoloration or appearance of dark spots on the skin. A lot of people observe darkening of different areas of skin.
Too much exposure to harsh sun rays can cause over production of melanin and discoloration of the skin. The ultraviolet rays present in sunlight can inflict a considerable amount of damage on the skin, which could lead to tanning and darkening of the skin and development of blemishes.
If skin is not cleansed properly after using cosmetics, they can block skin pores and cause acne and blackheads.
Exposure of skin to harmful chemicals, especially when they are present in the environment around us, can cause significant damage to skin. These chemicals can also cause discoloration of the skin and uneven skin tone. It is not only the chemicals in the environment that cause blemishes, but also chemicals present in makeup products, aerosols, cleaning materials, etc.
Genetics also plays a part in causing blemishes. Individuals having parents prone to this skin problem have a higher tendency of developing blemishes on the skin.
Some skin specialists say that food items such as chocolate could also lead to acne and blemishes on the skin.
There are no clinical studies at present to prove this claim though.
In most cases, a blemish is a symptom itself of an allergy, immune disorder or serious medical condition.
Some common symptoms associated with blemishes include:
All these symptoms may not appear in case of a blemish. Only some people experience all these symptoms, most individuals have uneven skin tone, scarring or acne marks.
Even though it is impossible to prevent some forms of blemishes such as birthmarks and effects of aging, the risks of acquiring other types of blemishes such as pimples and pustules can be significantly lowered through vigilant skin care. Applying sun block and avoiding exposure to sunlight and harmful chemicals can help prevent blemishes and uneven skin tone (11). Staying hydrated can help maintain the health of the skin. Washing your face properly on a daily basis with a cleanser that is suitable for your skin type is also important, as is applying a good moisturizer. Besides this, using breathable bandages, proper wound care, and anti-scarring cream can all decrease the chances of developing blemishes.
Prevention is better than cure
The best way to get rid of blemishes is prevention. If you want to stay blemish free for as long as possible to ensure that they not appear in the first place. Start treating blackheads, pimples, pustules and whiteheads as soon as they appear. Do not pop zits or pimples or try to extract whiteheads or blackheads forcefully.
Day to day skin care
Maintain skin hygiene and wash your face daily with a cleanser suitable for your skin type which is good for cleaning up excess sebum, dirt, and oil. Avoid use of harsh skin products or cleansing agents as they irritate the skin even more.
Avoid too much of sun exposure
Sun rays aggravate acne and cause blemishes and dark spots. To shield your skin from damage from the sun, apply a good amount of sun block with at least SPF 15 on exposed parts of your skin before you step out into the harsh sunlight.
Gently rub calamine lotion onto your face or wherever blemishes have appeared on your skin (12). Calamine lotion helps in drying up excess oil and sebum from the skin and thus effectively removes blemishes. Apply calamine lotion regularly on a daily basis.
Take a chunk of ice and wrap it in a clean towel or cloth. Apply the wrapped ice on the skin blemishes for a few minutes. This process will soothe the skin blemishes and decrease inflammation. Use this remedy as soon as a blemish is visible to get rid of inflammation and redness.
Increase intake of fluids and make sure that you drink enough water to stay adequately hydrated throughout the day.
Water will help to detoxify and cleanse your system. It will keep acne at bay by flushing out toxins. It will also give you a radiant and clear skin.
Eat a good diet
Make sure that you take a healthy, well- balanced diet. You should eat plenty of fresh fruits and green, leafy vegetables, which bring out a radiant glow on your face. A healthy diet will slow down aging process of skin and brighten your overall complexion and make blemishes appear less visible.
Opt for over the counter creams and lotions to treat blemishes and skin discoloration unrelated to acne. In cases like mild sunburn or moderate skin trauma, skin will return to normal once the injury heals. It is important to keep your skin moisturized while the skin heals. Some skin care products can also be used as a cosmetic cover - up to hide blemishes and marks.
Usually, blemishes disappear after a while but stubborn and persistent facial blemishes (such as the ones on chin or eyelids) caused by acne have to be treated with prescription medicine. Your dermatologist may prescribe an oral medicine, topical lotion, and cream or both to treat your blemishes (13, 14).
According to the American Academy of Dermatology, there is no quick cure for acne blemishes. You must be patient and continue with your treatment regimen. It will take at least four to six weeks before you will notice any improvement. Some acne medicines have been known to cause birth defects. If you are pregnant or plan to become pregnant, inform your doctor and take his advice before starting a treatment regimen.
In laser resurfacing, your dermatologist will remove the top layer of skin of your facial area to exfoliate your skin (15). This stimulates the cells under the top layer to secrete collagen, which gives your skin a radiant glow in addition and evens out your skin tone (15). According to a research conducted by the University of Michigan Health System, laser resurfacing is a good treatment course if blemishes are produced due to aging or sun damage (16). Duration of treatment depends on the severity of skin damage and how much time it takes to remove the discoloration of skin.
For severe blemishes and scars, doctors may recommend surgery. Blemishes that are rough, warty, flat, infected, or red or brown in color should be examined by a skin specialist immediately, as these are common danger signs of skin cancer. The Siteman Cancer Center in Washington Medicine School University cautions that skin cancer may develop in parts where other blemishes, such as pockmarks or burns, are already present. If your facial blemish displays any of the symptoms of skin cancer, your dermatologist may want to remove it as soon as possible through a surgical procedure.

They also absorb up excess sebum and oil, which significantly reduces chances of blemishes or pimples making an appearance. Just be careful to use a good moisturizer afterward as they may dry up your skin.
Three egg whites separated from yolks.
Wash your face properly with water and dry it. Separate the whites of eggs from the yolks. You can use as many as needed, but usually, two to three are adequate. Whip up the whites with a whisk until they become frothy, and allow them to sit for a few minutes. Apply the whisked egg whites on your face like a mask focusing on affected areas. Four layers are usually enough, but let the first one dry before adding another layer on top of it.

Afterward, apply a moisturizer suitable for your skin type.
Try some apple cider vinegar
Apple cider vinegar is an excellent choice for removing blemishes. It is bactericidal and eliminates acne causing germs (22). It also becomes alkaline and neutralizes pH of the skin, making it harder for bacteria to survive. A bonus point is that it’s an astringent and absorbs excess oil from skin.
Go light on its use though and don’t overdo it as it might dry up your skin. This could stimulate the sebaceous glands to produce extra sebum to compensate, thus triggering a breakout.
Things you will need are:
Wash your face with water and gently dry it. Keeping a proportion of 1 part vinegar to 3 parts water, dip cotton into vinegar and apply it directly to the marks or blemishes. Leave it on fro about twenty minutes. Repeat this process whenever you wash your face. Do use a moisturizer afterward if you feel like your skin has dried up too much.

Do not start taking any prescription medicine without consulting your dermatologist first as it may cause more harm than good.
Inform your doctor about your complete medical and drug history.
Avoid exposing skin to the sun after receiving laser therapy. The area being treated should not be exposed to sunlight. Ultraviolet rays irritate the area more and turn it red, so step out in sun after applying sun block of at least SPF 30 and cover affected area properly. The skin area after receiving skin laser takes some time to heal so handle it gently. Do not scratch, rub or prick it. If you get laser treatment of facial area, do not use harsh scrubs or cleansers and don’t shave.

How to differentiate between blemishes and melanoma?
If you are worried about your blemishes, have them examined by a skin specialist to check if they are benign or malignant. Consult a doctor immediately if you notice changes in size, color or shape of a birthmark or mole.
Blemishes usually disappear on their own so do not stress out as stress leads to further break outs. However, if they cause pain and discomfort contact a dermatologist.
Laser therapy, chemical peels, over the counter creams and lotions, etc. are used to treat blemishes.
Blemishes can be treated by using many home remedies as well such a lemon juice, turmeric powder, honey, apple cider vinegar, apples, etc. Home remedies are all natural and do not cause any side effects.
