What Are Blemishes?

A blemish is any form of mark, spot, discolouration or defect that arises on the skin. They can appear on any part of the body but mainly occurs on the face, back, chest, upper arms or any body parts that have hair follicles or open pores.  Face blemishes are common among most people.

Most of the blemishes are harmless. Some people go for treatment because of cosmetic reasons.

What Are the Causes of Blemishes or What Causes Blemishes on Your Face?

Here are some of the reasons why blemishes occur.


Hereditary reasons can be one of the causes of blemishes. There are some inherited disorders and conditions that lead to the formation of blemishes such as birthmarks, Mongolian spots, hemangiomas and Fabry disease which involves gene mutation, leading to dark, red spots.

Excess Oil Production and Clogged Pores

The excessive secretion of oil from the sebaceous gland in the skin results in the formation of pimples. It then results in the accumulation of dirt and dead skin cells leading to clogging of pores. It happens mostly in people with oily skin. It also occurs in adolescence due to the influence of androgen hormones. 

Viral and Bacterial Infections

Certain viral infections such as cold sore and chicken pox leads to the formation of skin blisters which finally results in blemishes.

Bacterial infections such as impetigo results in scarring which will take some time to fade. 

Exposure to Sun

Frequent or prolonged exposure to direct sunlight damage your skin. When the ultraviolet rays fall on your skin, they trigger the production of melanin resulting in overactivity. Excessive secretion of melanin gives the skin a darker shade. Some of the pigments bind together to form a clump which appears as discoloured blotches on the skin. The scattered clusters of melanin will take the form of freckles, moles, melasma and age spots.

Hormonal Changes

Acne breakouts are often associated with hormonal changes and abnormally high levels of androgens in the body. The scars left behind by acne are one of the main causes of blemishes. Hormonal acne mainly affects females as they are high levels of androgen during their puberty and also during their monthly periods. There is a chance of improving or worsening the acne during pregnancy and menopause as they undergo hormonal changes during this time. 

Improper Diet

Your skin may be affected by what you consume. Excessive consumption of oily and dairy products can worsen acne. Whole milk and low skimmed milk when consumed excessively increase the risk of acne breakout. Cheese and yoghurt are unlikely to increase the risk of acne. 


A high level of stress can undermine your skin health and your overall well-being. People who lead stressful life are susceptible to various dermatological ailments, especially acne. Emotional stress has been the primary contributor to the development and aggregation of acne due to certain neurogenic changes in the skin.

Certain Medications

Administration of certain medications such as corticosteroids, androgenic steroids, lithium and antiseizure drugs may cause acne as their side effects lead to facial blemishes. 


Some foods such as peanuts, shellfish, eggs, milk and wheat may cause allergic skin reactions which may lead to acne breakouts and blemishes.

Improper Skincare Routine

The accumulation of dirt, pollution or dust throughout the day, can lead to blemishes if you lack a proper skincare routine daily. Heavy make-up without proper skin care can also precipitate acne and blemishes.

What Are the Types of Blemishes?

When a pore is clogged at the base of the skin, the hair follicle wall ruptures within the dermis and nodules are formed. Since the infection is so deep, the rupture takes place under the skin rather than at the surface. Nodules can also be filled with pus, but you will never see a whitehead as the infection is so deep.

The nodules are larger than papules and normally have a diameter of 1 to 2cm. The nodules will appear on the skin at any level. They might be flesh-toned or crimson in blue. 


When the swelling and inflammation of the nodule becomes so intense, it damages the healthy skin surrounding it and destroys the hair follicle known as a cyst. This type of blemish is the most painful of them and is extremely prone to scarring. 

Ingrown Hair

When you use the hair removal methods like tweezing, waxing or shaving, there occurs ingrown hairs. Some hairs that grow back into the skin and become stuck are known as keratinocytes. The keratinocytes result in the formation of a red bump.

Acne Scars

The acne scars are formed as a result of damage to the skin’s dermis layer. Anything that opens the skin such as a pimple or a cut will cause scarring.  


They are tiny skin lesions that come in different shapes and sizes. They have a diameter of 1 cm. Their colours range from pink to brown. 


Pustules are developed from papules. As the bacteria that cause blemish increases, white blood cells are sent to the blemish to fight off the infection. The after-effect is the formation of pus which is a whitish substance made of dead white blood cells. The pustules are topped with pockets of yellow or white pus and have a red and painful base. 

Skin Cancer

Some blemishes are shown by the body as an indication of skin cancer. There are several types of skin cancers like basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Skin cancers can range in colour and appearance. Some look like dark moles with irregular borders while others look like yellow scabs or raised red bumps. If people are aware of the warning signals of skin cancer they could detect it earlier.

Blackheads and whiteheads

They are also known as comedones. Blackheads are open comedones that form when a clog of sebum and dead skin cells enlarges and widens the pore. But whiteheads are closed comedones that are covered by the skin. They are reddened and sensitive with pus-filled tips.  Both types of comedones are non-inflammatory and they are never painful or swollen. But sometimes they lead to inflammatory blemishes.

Age Spots

As you become older, your skin will be more prone to the damage caused by the sun’s UV radiation. With increasing age, your skin’s regeneration power will also decrease and finally, there comes a stage when your skin will not be able to outgrow the sun damage, leading to the development of age spots.


The birthmarks appear shortly after birth or at the time of birth. They can be of different shapes, sizes and colours. They are broadly classified into

Pigmented: Caused by an overgrowth of melanin-producing cells in a specific area of the skin. They are typically black or brown.

Vascular: Occurs when there is an abnormal growth or malformation of blood vessels underneath the skin. They appear as purple, pink or red.

Moles and port wine stains are common birthmarks. It will last for a lifetime. Hemangiomas and salmon patches usually go away over time.


Melasma is a non-threatening yet cosmetically distressing skin condition that is characterised by the development of dark spots on the skin. It occurs due to sun exposure and certain hormonal changes that trigger melanin overproduction. Melasma is fairly prevalent during pregnancy. Women who consume oral contraceptives or hormonal replacement also suffer from melasma.


This condition is characterized by the development of discoloured spots or patches on your body, especially on your face. Several factors can lead to the clumping of melanocytes or melanin-producing cells and eventually it results in hyperpigmentation or intensely pigmented patches of the skin. It is essentially a post-inflammatory skin reaction due to injury, burns, acne or other causes.

Cold Sores

Cold sores are tiny, red, fluid-filled blisters. They typically appear on the lips and around the mouth. These are painful lesions that may develop on the chin, cheeks and nose. Usually, these cold sores are caused by the herpes simplex virus. They are viral and highly contagious. The discharge starts after a few days of forming and then crusts over.


Milia are tiny white bumps that appear in clusters around the nose, eyelids and cheeks. They appear most commonly in newborns. They are also seen in adults, but it is less common. It occurs as a result of skin trauma (burns, blisters) or skin conditions such as rosacea and dandruff. People often mistake them for blemishes. They are made up of a protein called keratin which can be managed by a skincare regime incorporating AHAs, BHAs and retinoids.
