Fungal acne in singapore — this grossly underdiagnosed condition may be the reason why your acne treatments are not working

Understanding Acne

Acne is the most commonly diagnosed skin disorder in young adults. Although the problem can be more severe during our teenage years, it is not an adolescent only problem. In fact, recent studies have shown increase prevalence of adult acne, with up to 80% of acne cases persistent beyond puberty (1). The majority of those affected are ladies (82.1% in this study) but also possibly because ladies are more affected by their appearance.

Problems Acne Can Cause

Apart from the pain and irritation that happens during the active phase. Acne also results in:

  1. Skin blemishes in the form of persistent red or brown marks. These frequently need cosmetics to conceal and some cosmetics can exacerbate the problem.
  2. More severe lesions result in long term scarring because of the collagen destruction in the skin. Scarring is often difficult to conceal with cosmetics and was present in a majority (76.4%) of patients in one study (1).
  3. Psychological stress is common (52.8% in the same study) and one study (2) even highlights three psychological aspects in patients with acne:
    – Acne causes disturbances in self esteem, social phobias and depression
    – Stressful conditions tend to worsen the patient conditions
    – Primary mental illnesses such as anankastic disorders, OCD and psychoses focus the patient’s attention on scratching acne lesions, which secondarily deteriorates the skin condition, leading to a ‘vicious circle’.

What Causes Acne?

Adult acne has similar mechanisms as pubertal acne: oversecretion of sebum (oil), excessive production/shedding of skin cells blocking the pores, bacterial growth (propionibacterium acnes) and finally inflammation over affected areas.

In adulthood, the causes are frequently related to stress, hormone stimulation, cosmetic and inappropriate skincare use. Tropical weather was also found to be an exacerbating factor, believed to be due to oxidative damage of sunlight and sweating from the increased humidity.

Being multifactorial, I personally believe that every patient suffering from acne needs a personalised and detailed medical consult to detail the potential causes, aggravating factors as well as any loopholes in their skincare regime.

Since there are multiple steps in the mechanism for acne formation, it also makes sense that a combination of treatments is sometimes required for any improvement especially in cases which are more severe.

Prevention and Self-Care Measures

Prevention and self care are important parts of many medical treatments and acne care is no different. In fact, as your acne improves with medical treatment, proper care during and after can help prevent an unscheduled visit back to the doctor’s.

Use Proper Skincare


The type of facial wash is especially important in acne: a study conducted on the influence of cleansers on acne treatment showed that a suitably moisturising facial wash outperformed a pure soap and a benzyl peroxide wash (3).

Minimise Make Up


Minimise make up and use only non-comedogenic products. Never wear your make up to sleep and try to minimise the time it spends on your skin!

Moderate Stress Levels


Moderate your stress levels as these have shown to affect your hormone levels and in turn cause acne. Refer to the vicious cycle as described above.

Shower After Strenuous Activities


Shower after strenuous activities as oil and sweat on skin can lead to breakouts. Sunlight and excessive humidity can compound the problem too so use a good sunscreen and try to stay in cool and shaded environments as much as possible.

Avoid Touching Your Acne


Avoid rubbing and picking on the problem areas. Doing so can cause acne to spread and worsen existing lesions!

Different Treatments Available

  • Decreasing sebum levels: the use of oral and topical medications like retinoids and hormonal pills (for ladies) are an effective way for reducing oil gland secretions. Almost all laser treatments also shrink the size of these oil glands, which can be felt from the first treatment.
  • Normalising skin growth and shedding: this is usually achieved by topical retinoids (popular ones include Differin, Retacnyl) and oral options like Roaccutane. Salicylic acid (BHA), AHAs, Azelaic acid and Benzoyl peroxide (BPO) also possess mild comedolytic effects. These function clear out the pores, preventing the formation of new acne and allow the unplugged follicle better penetration by antibiotics. Medical peels like Araclear, certain resurfacing lasers and radiofrequency treatments such as the Venus Viva are also postulated to reset the skin growth cycle and normalise the growth and shedding of skin cells.
  • Killing the P. Acnes bacteria: antibiotics are the obvious choice for some forms of inflammatory acne and they are sometimes needed in oral and topical combinations. BPO has antibacterial effects on top of providing mild comedolysis. However, recent research show increasing antibiotic resistance in up to as many as 60% of acne patients (4). Thankfully, most laser and light treatments have shown to have good effects on eliminating this troublesome bacteria, something that they have not yet developed resistance for!
  • Reducing inflammation: the use of anti-inflammatory products such as salicylic acid, niacinamide and occasionally steroid injections are an effective approach to the most physically troublesome symptom of acne. Pulsed-dye lasers such as the Pro-Yellow laser have been shown by multiple research studies to reduce inflammation which can greatly reduce the number of inflammatory acne lesions. On top of this, the Pro-Yellow has also been found to be bactericidal, decrease oil secretion as well as stimulate dermal collagen production to even out scars. These features make it a powerful workhorse for treatment of acne and a convenient all-in-one treatment option.
"Treatments for acne target the different steps in its formation mechanism. It is important that a qualified physician understands these steps, the intricacies of each different product or treatment, and is well versed about the appropriate combination of use. Attempting to use these products without proper medical supervision can result in futile treatment, or sometimes even worsening of skin health."

Laser Treatments For Acne – Yay or Nay?

Oral and topical treatments are quite effective for acne but most of them take a few weeks to show its effects. Also, poor compliance to treatment, lack of long-lasting results and potential side effects from medications are common drawbacks to these treatments. As such, the use of laser and light treatments for acne has grown very popular recently because they effectively target multiple parts of the mechanism as shown above, do not need daily maintenance, has minimal side effects and predictable clinical efficacy.

Depending on your condition and your lifestyle, a combination of different laser and light treatments usually can speed up recovery from acne. My favourite part of laser treatments for acne is that it is almost always accompanied by other desirable effects such as skin rejuvenation, lightening of pigmentation and scar resurfacing. Consult your doctor early to find out how a combination of medical grade treatments can help you – early is better than late treatment otherwise much money and effort needs to be spent to treat its sequelae as well.
