Guide to Acne and Acne Treatment

Acne (clinically known as acne vulgaris) is the most common skin condition that affects 5.6 million Canadians with more than 80% of the cases occurring between the ages of 12 and 24. Acne occurs when pores become clogged with dead skin cells and oil from the skin.

Acne occurs not only on the face but can occur on the body – most notably the back, chest, and shoulders. Acne comes and goes when we are teenagers due to hormonal changes. However, some people suffer from persistent acne and acne scars which can lead to anxiety, lowered self-esteem, and depression.

There is no one-size-fits-all solution for fighting acne which often leads to worsened symptoms, confusion, and frustration. Despite being one of the most common skin conditions in the world, relatively little is known about its cause. However, promising research over the years has provided us good knowledge on how to approach and treat acne. Continue reading to learn more!

What is Acne?

Acne psilosebaceous unit

Acne is an inflammatory disorder of the psilosebaceous unit which is made up of sebaceous glands, hair follicle, and hair.

Naturally occurring hormones called androgens signal sebaceous glands to produce oil called sebum that coats the skin and hair in protective oil to keep them moisturized and healthy. When there is too little sebum production, dryness and irritation on the skin may result. When there is too much sebum production, an overly oily appearance on the skin may occur which increases the risk of acne. Acne forms when the affected hair follicles become clogged with sebum and dead skin cells from the skin.

Swelling and infection occurs when bacteria called Propionibacterium acnes (P. acnes) induce an inflammatory response from the body resulting in acne.  There are many types of acne and in the next section we’ll explore the different types of acne and severity of each type.  

Types of Acne

Acne is a broad term that includes blackheads, whiteheads, papules, pustules, nodules, cysts etc. While the definitions on the severity grades of acne vary, most acne can be categorised into three main categories of: mild, moderate, and severe.

Blackheads and whiteheads are both mild forms of acne. Blackheads (also known as open comedones) form when pores become clogged and remain open. The debris in the open pore reacts with the air and becomes oxidized.  This causes the appearance of black dots on the pore surface. Whiteheads (also known as closed comedones) are clogged pores that are closed or have a narrow opening so it does not oxidize with the air, causing the acne to appear white.

Moderate forms of acne involve papules and pustules. Papules are advanced forms of whiteheads that are red or pink bumps with a swollen appearance. When bacteria become trapped in the pores along with oil and dead skin cells, this causes white blood cells to enter the hair follicle, creating inflammation. Pustules are very similar to papules except that they are filled with pus (white blood cells, dead skin cells, and bacteria) and are painful to the touch. Pustules look like white/yellowish bumps surrounded by a red ring.  

Lastly, severe forms of acne are in the form of nodules and cysts. Nodules occur when an infection occurs deep within the skin which causes the pore to become red and swollen. Nodules feel like hard knots under the skin and can last a long time – even months. Cysts are similar to nodules but are filled with pus and look similar to boils. The deep infection in both nodules and cysts makes them hard to clear with over-the-counter (OTC) products, often requiring consultation with a dermatologist.

There are many types of acne but how do they occur in the first place? Next, we discuss some commonly known causes of acne.

What Causes Acne?

As previously mentioned, over-production of sebum can cause acne. However, there are other factors that contribute to the formation of acne. Some factors are not in our control but some can be prevented or controlled through lifestyle changes.

Uncontrollable causes of Acne:

  1. One cause of acne that cannot be controlled is largely due to natural hormonal changes. This is most evident in teenagers when they are undergoing puberty and the occurrence of acne is much higher than adults. You can learn more about teenage acne by clicking here. However, hormonal triggers causing acne is not exclusive to teenagers and many adults are similarly affected.
  2. In addition, taking certain medications can induce the formation of acne. Medications can cause hormone levels to fluctuate thus leading to breakouts. Unfortunately, some medications cannot be avoided for specific individuals due to other health complications.
  3. Lastly, another cause of acne that cannot be controlled is due to genetic reasons. Acne tends to run in families as those who have first-degree relatives with adult acne tend to be more likely to develop acne themselves.
What you can do to control acne

Controllable causes of Acne:

  1. Cleansing your skin will clean off bacteria, built up dirt, and excess oil which will reduce the chance of breakouts. However, frequent cleansing or over-stripping the skin’s natural oils will cause your skin to panic and overproduce sebum, which ends up increasing the risk of breakouts.
  2. Another hygienic practice to prevent acne is frequently changing your pillowcases. Just as bacteria, dirt, and oil building on your skin over the day, these accumulate on your pillowcase and cause breakouts. If you are a severe acne sufferer you should change your pillowcase daily.
  3. Moreover, using the right ingredients and products on your skin will reduce your chance of acne. Some products are comedogenic which means that the ingredients clog pores. If you are prone to acne, use non-comedogenic products for your skin care.
  4. Eat low-glycemic foods and avoid high-glycemic foods as they are known to worsen acne. High-glycemic foods include sugary foods, soft drinks, white bread/rice, and potatoes. In some cases, cutting out dairy products showed a reduction in the occurrence of acne. 
  5. It can be hard to do but resist picking or popping acne.  This can cause more inflammation, risk of infection, and take longer for your acne to heal. It also increases the risk of acne scars so acne pore clearance should only be done by a clinician.

If you’ve tried these methods and your acne still doesn’t seem to be going away your acne requires more advanced treatment.  It is likely now time to seek professional help.

Acne and Acne Scars Treatment

Mild to Moderate Cases:

In most mild to moderate acne cases, topical treatment is a great start or sufficient for preventing and treating acne. There are many ingredients that are effective against acne but three ingredients are well-known and studied: Salicylic Acid, Benzoyl Peroxide, and Retinoid/Retinol. Each of these products has different purposes in treating acne so all three of these may be used in your treatment plan.

  1. Salicylic Acid is a type of beta-hydroxy acid (BHA) that exfoliates dead skin cells on the skin that are clogging pores. At the same time, Salicylic Acid improves skin texture and tone. You’ll usually find these acids in concentrations ranging between 0.5 – 2%.
  2. Benzoyl Peroxide works by penetrating deeper into the skin and kills the acne-causing bacteria in pores. It also helps remove excess oil on the skin, but is relatively more drying than Salicylic Acid. In cases where topical antibiotics are given to treat acne, Benzoyl Peroxide is a great addition to prevent antibiotic resistance.
  3. Retinoid/Retinol (Vitamin A) is best-known for their anti-aging properties but also unclogs pores and dissolves dead skin cells. It also prevents acne and acne scars from forming. Retinoids are stronger but must be prescribed whereas Retinols are OTC but slightly less potent. Retinoids/Retinols also possess anti-inflammatory benefits.

All three topical products may be used together but it’s best to consult a professional to create a safe skin care routine for you. Mixing these topical treatments in the wrong order or within the wrong skin care routine can cause irritation or worsen symptoms. Overusing the products can also cause irritation but is easily resolved with proper lotion and creams in most cases.

Moderate to Severe Cases:

For severe cases such as nodules and cysts, it is best-advised to visit a dermatologist. A dermatologist may prescribe stronger doses for topical applications or provide oral medications. Some cases might require a mix of treatment options used together to treat the concern. In other cases, invasive procedures such as making an incision on the skin and draining pus might be required.

Do not pop or prick your nodules and cysts as doing so will aggravate the acne and make symptoms worse. The healing process will take longer and highly increases the risk of acne scars. A professional can unclog your acne in a safer and less risky way.

Be patient with your skin care professional as approaching acne (regardless if it is mild or severe) is a complicated and long process. You’ll seldom see quick results as most topical treatments require at least 6-8 weeks before improvement is seen.

Treating Acne Scars:

While mild acne is relatively simple to treat in most cases, acne scars are another equally or bigger concern. Acne scars are reddish or brownish marks that remain after the active acne disappears. These scars last months or even years without proper treatment.

Once your acne is under control, it is advised to change your skin care routine to an acne/hyperpigmentation routine so that you can treat any resulting PIH (post-inflammatory hyperpigmentation) and scars resulting from your acne.  

In many cases, a chemical peel treatment can help improve the appearance of acne scars. For advance cases, laser treatment or microneedling are good options to consider.

Remember to consult a professional so that you don’t make the hyperpigmentation worse!

And in Closing...

Acne is a complicated skin disorder with a variety of treatment options available. It is advised to consult your skin care provider on the best treatment option for you. Remember to do your part in keeping up with good skin care habits and remember that treating acne and acne scars take time and commitment.
