Acne can be a very distressing ordeal that a lot of you may already have had to encounter. Some people say it’s a rite of passage; a journey we all have to take as we go into puberty and will subside as we grow older.

But what if the acne doesn’t go away? Some of us have acne longer than we’d hope for, following us well into adulthood. A study in Singapore revealed that 41% of adults treated at the National Skin Centre had dealt with acne since their adolescent years and that majority of them suffered from adult-onset acne. [1]

Fret not! With advancements in technology, modern medicine has a plethora of ways to deal with various acne conditions. Let aesthetic doctor, Dr. Lim Luping, walk you through all you need to know about acne removal treatments such as the types of medication, in-clinic procedures costs and many more.

Learning about acne and acne removal treatments can help give you a better idea of how to deal with even the most severe outbreaks.

What is Acne?

Acne is a chronic or long term skin condition affecting the hair follicle and sebaceous gland, which are both part of the pilosebaceous units in the skin. The sebaceous gland naturally opens into a hair follicle to secrete sebum — a combination of complex oils that help protect the skin from dehydration, bacteria, and other important functions.

Acne occurs when the hair follicles become clogged up with oil and dead skin cells. They present on the skin as comedones or inflamed red and angry bumps with or without pointing pus.

What are the common types of Acne?

Acne conditions can be divided into two broad categories:

  • Non-inflammatory acne
  • Inflammatory acne

Non-Inflammatory Acne

Closed Comedones — usually <0.5mm and skin-coloured bumps.

Open Comedones — <0.5mm, skin-coloured bump with a black pore opening

Inflammatory Acne

Inflammatory acne occurs when bacteria C Acnes infect the comedones resulting in inflammation, redness, and swelling.

Inflammatory acne can be further classified into 4 other groups based on their appearance and diameter.

  • Papules
    These are between 0.5mm to 0.5cm red, swollen, firm bumps which may be tender.

  • Pustules
    These are between 0.5mm to 0.5cm red, swollen, and tender bumps with a white or yellow pus tip, pointing and ready to burst.

  • Nodules
    These are over 0.5 cm red, firm, and tender bumps.

  • Cysts
    These are over 0.5 cm bumps filled with pus ready to discharge, red and painful. Occurs when blockage and inflammation occurs deep in the hair follicle

Common sites of acne are the face, forehead, chin, chest, upper back, and shoulders as these areas have the most oil glands.

Severe Acne

What causes Acne?

Acne is caused by a series of issues that affect the pilosebaceous units in the skin. What is directly impacting the acne formation is based on a list of physiological events at the skin, namely:

Main causes of Acne

  • Excessive sebum production — Sebaceous glands produce too much sebum or oil compounds which accumulate at the hair follicles.

  • Improper exfoliation — The dead cells of the hair follicles do not exfoliate properly due to inadequate vitamin A in the follicles, thus plugging them with dead cells, sebum, and other debris.

  • Bacterial growth — A rise in C. Acnes bacterial activity within the clogged follicles, then possibly bringing inflammation in the form of acne outbreaks.

Looking deeper, there are some underlying factors within your own body that could be the root of or further worsen your acne outbreaks.

Underlying Factors Contributing to Acne

  • Genetics — If one or both parents have had acne conditions, then it increases the chance of their children having acne.

  • Pubertal years — Acne occurs mostly between 12 and 30 years old. In fact, 80-85% of people with acne fall into this age group, where there is an increase in androgens, or male hormones, in the body.

  • Hormonal changes in midlife — Hormonal changes can result in acne especially in women when the balance between the estrogens and androgens is disrupted.

  • Stress — Stress can aggravate acne as well due to the resultant hormonal imbalances.

  • Medications — Certain antidepressants, steroids, and lithium may worsen your acne conditions.

  • Medical conditions — Some medical conditions may result in an overproduction of androgens such as polycystic ovarian disease syndrome (PCOS).

How is Acne diagnosed?

As with any medical condition, a diagnosis involves a physical examination of the exhibited symptoms and taking note of the patient’s medical history.

The physical examination for an acne diagnosis will cover the areas of the body which contain the most oil glands such as the face, jawline, shoulder, neck, chest, and back.

The doctor will take note of the different types of lesions or acne formations which can possibly be a combination of comedones, papules, and pustules.

How is Acne treated?

Acne treatment is administered based on the severity and types of lesions that we observed during the examination.

General treatment options for acne include topical and oral medication. An exhaustive list of the possible treatment options are as follows:

Treatments that can be administered at home

  • Topical medication — Such as acne creams, gels, lotions, and washes. However, proper application of medication should be advised or they may irritate the skin and aggravate the condition further.

  • Oral medication — Such as oral supplements, antibiotics, contraceptives or isotretinoin

Treatments that are administered in-clinic

  • Acne Removal energy devices — Such as Acne Clear Laser treatment, Intense Pulsed Light (IPL) treatment, Light-emitting diode (LED) treatment and fractional radiofrequency treatment

  • Therapy treatments — Ultrasonic extraction, Plasma treatment, Acne hydra peel, Chemical peels

Depending on the severity of acne, different treatments can be recommended. Usually, a combination of treatments can result in a synergistic effect and faster control of the condition.

The most effective treatment route will be able to target the main causes of acne by reducing sebum overproduction, normalising the hyperkeratinization of the cells to improve skin exfoliation, reduce bacterial growth on the skin and hair follicles and prevent inflammation.

We can work to resolve the acne condition, minimise scarring as the acne heals, manage skin globally to prevent new acne from developing, and prevent future scarring.

Acne removal treatment

What do I do for Acne Removal if over the counter creams do not work?

Generally, counter creams would work if your acne is mild. Mild acne means that there are less than 5 small acne bumps and should resolve quickly within the week without scarring. Mild acne usually occurs only once in a few months.

Aside from that, anyone who has acne cyclically or persistently requires medical help.

For instance, premenstrual acne would be most effectively treated by oral contraceptives to overcome the heightened androgen levels. If your acne condition is made up of a combination of papules and pustules, oral antibiotics and topical treatments should be sufficient for acne removal.

Beyond that, if the above treatments prove ineffective, you may need to progress to in-clinic options which could involve laser treatments, extractions, chemical peels, and oral isotretinoin.

What are the complications of Untreated Acne?

Untreated acne can lead to a range of different problems that can have a lasting effect on the patient.

  • Scarring — Untreated acne can lead to scars that are potentially permanent such as ice pick scars, box scars, rolling scars, or atrophic scars.

  • Blemishes —**There could also be darkened spots due to hyperpigmentation or post-inflammatory redness that can take a long time to fade


  • **Psychological issues — With these long-term changes to your appearance, it may result in reduced self-confidence and self-esteem. In some cases, people may deal with depression with the potential impact it has on their social life.

Acne removal treatment is recommended if you have:

  • cyclical acne
  • continually-active acne
  • aggravated acne

Depending on how big the lesions are, the continual production of acne will possibly result in large or small scarring.

Even though effective treatments for acne scars are available, if the scars are too deep, the complexion cannot revert completely to the pre-acne smoothness, scarless and poreless condition. Acne scar treatments also tend to be more costly.

It is advised to seek professional medical advice if your acne condition seems to be persistent despite self-administered treatment, to prevent permanent damage to your skin.

What are the specific Topical Prescription Medications for Acne Removal?

Topical medication such as salicylic acid, lactic acid, and glycolic acid can improve the exfoliation of dead cells so that the sebaceous glands are not clogged up. Their drying properties help to reduce oil production as well.

Benzoyl peroxide has antibacterial properties [2] which can be combined with topical antibiotics to reduce the antibiotic resistance effect.

Topical medication also includes Retinoids, Tretinoin, Differin and Epiduo which can come in different strengths and mediums such as gel, lotion, or creams. They reduce the overproduction of dead cells and prevent the clogging of the hair follicles. This leads to a reduction in comedone formation.

These topical medications are applied over the active acne areas and other acne-prone areas of the skin. With regular use in low doses, they can reduce fine lines and improve the texture of the skin too.

Topical antibiotics such as Erythromycin and Clindamycin work to reduce bacterial growth on the face to prevent any inflammation of comedones.

There are also new supplement formulations available from doctors’ clinics that include combinations with vitamin B3, zinc, green tea (epigallocatechin) antioxidants, triethyl citrate, ethyl lanolate, GT peptide, and honokiol.

These have a combined effect in:

  • reducing sebum production
  • normalising keratinisation of the skin
  • conferring anti-microbial properties
  • helping with inflammation symptoms and improving the skin healing process.

What are some side effects of using medication for Acne Removal?

Some topical medications such as acid-based products like alpha hydroxy acid (AHA), beta hydroxy acid (BHA), tretinoin, and salicylic acid have a drying effect and can cause irritation if they are not used properly. This is especially so for people with sensitive skin which can result in redness and irritation after usage.

Topical antibiotics, if overused beyond 6 months, may lead to antibiotic-resistant bacteria which make using further antibiotic treatments ineffective in dealing with acne.

Oral antibiotics may cause stomach upset with prolonged use, which can also cause antibiotic resistance.

In rare cases, using oral contraceptives may result in weight gain or depression.

Oral isotretinoin is unsuitable for females who are trying to or already are pregnant as it may affect the health of the fetus. Cholesterol levels may also be increased but the occurrence can be detected during the doctor’s pre-treatment examination to check your cholesterol levels in the first month.

  • skin irritation
  • redness
  • peeling
  • itching
  • stinging
