What causes acne?

Acne is a common skin condition which leads to spots on the face, back and chest- it is most common in the teens and twenties, though some people also get it later in life.
Normal skin has “sebaceous glands” which produce natural oils.
During puberty, the skin produces more of these oils, which may cause blockage of the sebaceous glands.
The trapped oils in the glands allow bacteria (Propionibacterium acnes) to multiply. Dead skin cells may also build up in the pores.
This in turn results in an immune reaction, inflammation and infection in the skin.
Experts are not sure why some people get acne while others don’t, but there seem to be some factors involved, including: hormonal changes during puberty, PCOS (polycystic ovarian syndrome), other hormonal disorders, smoking, stress, exhaustion, using oily skin products, family history of acne.
Some medications may make acne worse, such as progesterone only contraceptives, steroid creams (used in eczema), anabolic steroids, Lithium and some antiepileptic medications.
It is not certain whether diet has any effect on acne, though some people find that cutting down on processed meats and refined carbohydrates may help. Others report that eliminating milk-based products helps, though there is no clear scientific evidence this is effective for most people. There is also no evidence about any benefits from vegan or vegetarian diets, or from taking probiotics.

Can acne lead to scars?

jforrester@qoctor.com.au — Sun, 22 Oct 2017 06:01:20 +0000

Acne is common, but only one in five people with acne get scarring. Scarring is caused when the affected skin pore swells and breaks down into the surrounding tissue. The skin responds to repair the area, by forming new fibrous tissue, “collagen”. Scars can form in different ways: if there is a loss of tissue in the area, this can leave an indentation, such as “ice pick scars”, “rolling scars” or “boxcar scars”. A raised scar can form where too much collagen is produced- these are also referred to as hypertrophic or keloid scars.

Regardless of the type of scar, there are treatments available if necessary, so if you are troubled by acne scars you can discuss your options with a GP or dermatologist.

If at any time your acne seems severe or uncontrolled, especially if you have large painful acne cysts, it’s important to speak to a doctor, as you may benefit from a referral to see a dermatologist to get stronger treatment, to prevent further lesions and scarring.

The online doctors at Qoctor can offer assessment for acne that is mild to moderate.

What are the various options for topical treatment of acne?

Every person is different. Some people can successfully manage their acne with over-the-counter creams and gels from the pharmacy. Others may need stronger prescription-only creams and gels. These treatments work in a variety of ways, and depending on the type of acne spots, certain ones may be more effective.

Non-inflammatory lesions:

Whiteheads or “closed comedones”– these are closed, oil-plugged pores.
Blackheads or “open comedones” -these are open plugged pores — the oil turns brown when it is exposed to air.

Inflammatory lesions:

Papules- these are small, sore red bumps
Pustules- these are also known as pimples, and are papules containing pus
Nodules- these are large, solid, painful lumps under the skin
Cysts- these are large, painful, pus-filled lumps under the surface of the skin

Benzoyl Peroxide and Salicylic Acid

The most commonly used over-the-counter cream is Benzoyl Peroxide- a big advantage of this product is that bacteria don’t get resistant to it over time. It can help a variety of the lesions described above, particularly if used with a retinoid cream/gel (see below). It’s also often used with antibiotic creams or pills to stop bacterial resistance developing. Salicylic acid is also present in quite a few over the counter creams, cleansers and face-washes- it breaks down comedones, and may be of some benefit.

Retinoids and Topical Antibiotics

Prescription-only topical treatments known as “retinoids” are used in mild to moderate acne- they can prevent the formation of comedones (blackheads and whiteheads). They may also helpful against inflammatory lesions such as papules and pustules. They may be recommended by themselves for non-inflammatory acne (comedones), but WITH antibiotics if there is inflammatory acne present (papules, pustules). They can be helpful also when oral treatments are being stopped, to try to maintain any improvements achieved. Topical antibiotic preparations are used for mild to moderate inflammatory or mixed acne, but it’s usually recommended they are used along with Benzoyl Peroxide to prevent antibiotic resistance.

Please note, all treatment and advice is issued subject to your consultation and the doctor’s assessment.

Is the contraceptive pill used to manage acne?

jforrester@qoctor.com.au — Sun, 22 Oct 2017 05:59:02 +0000

In some girls and women the pill (or COCP) can be used in the management of acne. The pill reduces the amount of “androgens” (male sex hormones) circulating in the body. Androgens are present in the female body, and may be associated with acne, as they cause the skin to produce more “sebum” (oils), particularly during puberty. The pill can address this. It is important to note that the “mini pill” or “progesterone only pill” does not reduce circulating androgens, thus does not appear to help acne in this way. Also, different brands and formulations of the COCP exist, and different ones may be more effective than others, in different individuals.

Some women find the pill doubly useful as a way to manage their contraception needs as well as their acne.

What can a dermatologist do for acne?

A dermatologist can assess your acne and may choose to prescribe many of the same treatments (creams, gels, antibiotics) that may be prescribed by a GP, but a dermatologist can also offer additional advice and management options for acne that is not well controlled. Dermatologists can prescribe Isotretinoin (Roaccutane), as well as other specialist treatments for acne scars. It is important to consider seeing a dermatologist if you have bad acne that is not responding to treatment, particularly if scars are occurring.
