How to relieve from acne
"Occasional
pimples need no treatment, but in serious cases you and your healthcare
provider can determine the right treatment."
Topical treatments
Topical retinoids
These are chemicals derived from the vitamin A molecule and include tretinoin, adapelene and retinol. They’re best used in the early stages of acne and are the best topical treatments for blackheads and whiteheads. The “original” retinoids (e.g. tretinoin) are very effective, but they tend to be more irritating to the skin and therefore can’t be used by everyone. Adapelene and retinol tend to be less irritating.
These products are best used at night and
should be introduced to the skin slowly to build up a tolerance. A good idea is
to use them at night on a Monday, Wednesday and Friday for at least two weeks.
Then, assuming that they’re well tolerated, you can start using them every
night.
Tretinoin and adapelene require a
prescription from a doctor, whereas topical retinols don’t. It’s generally
recommended that these products aren’t used during pregnancy or breastfeeding,
as no adequate, well-controlled human studies have proven that they’re safe. It’s essential to use a high-factor,
broad-spectrum sunscreen on a daily basis while using topical retinoids, as
they may make your skin more sensitive to the sun.
Azelaic acid
Azelaic acid (Skinoren) helps to unblock
pores, and has anti-bacterial as well as anti-inflammatory effects. It’s
available in a cream as well as a gel, and is generally well tolerated.
People with acne and darker skin often
develop dark spots at the site of the previous pimple – a condition called
post-inflammatory hyperpigmentation (PIH). It’s been shown that azelaic acid
can lighten this pigmentation. Azelaic acid is safe to use during
pregnancy and lactation.
Cleansers, moisturisers and
sunscreens
Most people with acne have oily skin, so
it’s best to cleanse the skin with a mild, foaming cleanser. However, some people (with a background
history of eczema) may have more sensitive skin. If this is the case, it would
be best to use a cream-based cleanser. It’s fine to use a mild toner such as a
Micellar water to remove make-up. Note, however, that harsh, abrasive scrubs
tend to irritate the skin and aggravate acne.
All moisturisers and sunscreens should be
of a light-weight formulation, oil-free and non-comedogenic (doesn’t block
pores). Look for "dry touch" sunscreens.
Benzoyl peroxide
This is a very useful agent that kills off the Propiobacterium acnes bacteria that cause the red bumps and pustules typical of acne.The great advantage of benzoyl peroxide is that it tends to prevent bacterial resistance to antibiotics. It may be used on its own or in combination with topical retinoids or topical antibiotics such as clindamycin.
It’s available in various concentrations, but a popular choice is a 5% benzoyl peroxide gel (Benzac AC 5 Gel), used in the morning as a spot treatment and applied to red bumps and pustules.
The only side effect is that it can bleach clothing and linen. For this reason, it’s important to wash it off your fingers after use. If you use it on your body at night, it’s best to wear an old T-shirt to prevent bleaching your sleepwear or linen. Most dermatologists consider benzoyl peroxide safe for use during pregnancy and lactation.
Salicylic acid
Salicylic acid is available in many
anti-acne products and helps to unblock pores. It’s available in various
concentrations and is generally well tolerated.
If salicylic acid is used in a lower concentration (2%), and as a spot treatment only, it’s safe to use during pregnancy.
If salicylic acid is used in a lower concentration (2%), and as a spot treatment only, it’s safe to use during pregnancy.
Topical antibiotics help to reduce an
overgrowth of bacteria. Unfortunately, there’s increasing bacterial resistance
to antibiotics, especially topical erythromycin. This is often why the
antibiotic is combined with benzoyl peroxide. A useful combination is
clindamycin with benzoyl peroxide (Clindoxyl Gel).
The topical antibiotics are generally deemed to be safe in pregnancy and lactation, especially if used as a spot treatment.

Systemic treatments
The next step in the treatment of acne (i.e.
when acne becomes more inflamed with multiple red bumps and pustules) is
systemic treatment (oral medication).
Hormonal treatment
All acne is hormonally linked. For this reason,
hormonal treatment is especially useful in women who want contraception and
also suffer from acne.
Most ordinary, combination-type oral
contraceptives are effective in the treatment of milder forms of acne. In
slightly more severe forms, it’s useful to combine an oestrogen with an
anti-androgen, i.e. a medication that blocks the action of the male hormone
testosterone on the skin (Diane 35). Unfortunately, a small percentage of women
may put on weight with this hormonal pill.
Women with darker skin
should avoid excessive sun exposure and use a high-factor, broad-spectrum
sunscreen on a regular basis to prevent the formation of pigmentation or
melasma while on this hormonal treatment.
This type of hormonal treatment is just as
safe and effective as any other normal combination oral contraceptive pill.
It’s also very useful in women with a hormonal imbalance such as polycystic
ovarian syndrome (PCOS). These hormonal pills usually regulate the menstrual
cycle, improve acne, reduce excessive hair growth on the face, and reduce
thinning of the hair on the scalp.
Antibiotics
The most commonly prescribed antibiotics
are the tetracycline group. One of the safest and best tetracycline antibiotics
is lymecycline (Tetralysal). It’s very effective and has few side-effects.
Doxycycline (Cyclidox) is another commonly prescribed antibiotic, but it can
cause sensitivity to the sun and upset the gastrointestinal tract.
These antibiotics have an anti-bacterial as
well as an anti-inflammatory action on the acne. They should, however, not be
used for longer than four months. Tetracyclines should also not be used
during pregnancy or while breastfeeding.
Systemic isotretinoin
There’s essentially only
one drug that can put acne into remission: isotretinoin (Roaccutane), taken
orally. Isotretinoin is derived from vitamin A and works by means of three
mechanisms:
- It reduces sebum production.
- It has as an anti-inflammatory action. Nobody in this day and age should end up with permanent scarring from acne. Oral isotretinoin is the best treatment, especially for the more severe forms of acne. It’s also indicated where other treatments have failed.
- It makes the top layer of the skin, the stratum corneum, less sticky (thus helping to control blackheads).
Isotretinoin is however a powerful drug
that needs to be given under supervision, preferably by a healthcare
practitioner who is experienced in prescribing the medication. The treatment
generally lasts six to eight months. As it makes you more sensitive to the sun,
it’s often best to take it during the winter months in South Africa.
Isotretinoin may affect the liver and raise
blood cholesterol (although this is rare). For this reason, your doctor will do
blood tests before prescribing the medication. It’s essential to either abstain
from alcohol or to keep intake to an absolute minimum while on isotretinoin.
It’s also incredibly
important not to fall pregnant while taking the medication, as there have been
reports of abnormalities in the foetuses of women who took the drug. A
pregnancy test should be performed before commencing isotretinoin treatment,
and a fertile, sexually active woman must use very effective contraception
while on the medication.
Adjunctive treatments
- Every blackhead and whitehead will eventually become a pimple, so a deep cleanse with comedone extraction by a trained skin therapist is very useful to remove the whiteheads.
- Oral as well as topical vitamin A products help for open comedones (i.e. blackheads), but will not help for closed comedones or whiteheads.
- Various lasers, especially Intense Pulsed Light (IPL), can be useful for treating inflamed acne. The intense, pulsed light acts on the overgrowth of the bacteria in the hair follicle, so it has an anti-inflammatory as well as an anti-bacterial action. This is especially useful in persons reluctant to take antibiotics, those who are allergic to the tetracycline-type antibiotics, or in people who prefer not to take isotretinoin.
- Chemical peels containing glycolic acid or salicylic acid are also useful for the more comedonal acne.
- If a person has a few larger, deeper acne cysts, a very useful technique is to inject cortisone into the cysts. This will cause immediate shrinking of the cysts, but has to be done by an experienced doctor, preferably a dermatologist, as you don’t want to inject too much cortisone into the cyst.
- A fairly unique treatment for acne is the Acleara Acne Clearing System (Theraclear). This dual-action treatment combines IPL with a special vacuum action that deep cleanses the pores by extracting blackheads and whiteheads. The IPL is a broadband light that targets porphyrins (a metabolite produced by the P. acne bacteria). In this way, it helps destroy the bacteria, while reducing sebum production. It’s also very effective at reducing erythema (redness). This is a useful treatment in pregnant women who can’t take systemic antibiotics or isotretinoin. The treatment is available at various dermatological practices in South Africa.
Treatment of post-acne scarring
The more severe types of acne can
essentially produce two types of scarring:
Raised hypertrophic or
keloid scars
These tend to occur along the jawline or
upper trunk in men as well as women. They’re usually a complication of the more
severe forms of acne and often occur in people who tend to fiddle or pick the
acne lesions. In the early stages, a topical silicone gel (Kelocote Gel) may be
helpful. But for the more raised keloid scars, a combination of laser with
cortisone injections into the keloid scars is best. This will require a number
of treatments. But with proper treatment, you should be able to flatten the
scar.
Depressed or atrophic scar
These sometimes have the
appearance of sharp depressions, which dermatologists call “ice pick” scars.
These scars are more difficult to treat. Their appearance can be improved, but
they may not be completely cleared. Useful treatments include medical
micro-needling such as Dermapen, as well as fractional lasers.
Treatment of pigmentation
In people with darker skins and more severe
forms of acne, it’s very important to use a lightweight, dry-touch,
non-comedogenic, broad-spectrum sunscreen to prevent the formation of brown
marks at the site of the acne. This is called post-inflammatory
hyperpigmentation (PIH).
Although they’re not scars as such, these
brown marks can be very distressing. There are various treatment options
available to people with PIH, including topical retinol, kojic acid, arbutin,
azelaic acid and, in more severe forms, topical hydroquinone.
Complementary/alternative treatments
- Gluconolactone is a polyhydroxy acid derived from a naturally occurring yeast. This has been shown to help for acne, thanks to its anti-inflammatory effects.
- Topical tea tree oil has been shown to have anti-bacterial and anti-inflammatory effects. It has a fairly slow onset of action, and a small percentage of people develop an allergic reaction to the tea tree oil.
- A 2% lotion of green tea, applied topically, has also been shown to be useful in mild acne. Green tea has anti-bacterial and anti-inflammatory properties.
Many
of the above naturally occurring products are found in various concentrations
in cosmeceuticals. These are available over the counter without a prescription.
Acne treatments in pregnancy
Acne often improves during the first
trimester, but may worsen during the third trimester of pregnancy – a result of
an increase in maternal male hormone concentrations.
Dermatologists recommend cleansing the skin
with a gentle cleanser, and to avoid harsh scrubs. Cleansers containing low concentrations
of salicylic acid (2.0%) and glycolic acid are considered safe during
pregnancy.
Topical products that can be used safely as
a spot treatment, according to the American Academy of Dermatology, include
topical erythromycin, topical clindamycin, azelaic acid, 2% salicylic acid, and
5% benzoyl peroxide.
Even though the package inserts in many of
these anti-acne products state that their safety during pregnancy hasn’t been
established, they are deemed safe to use by authorities like the American
Academy of Dermatology and the Food and Drug Administration (FDA).
- Oral isotretinoin (Roaccutane)
- Oral hormonal treatments
- Oral tetracyclines
- Topical isotretinoin (Isotrex Gel)
- Topical retinoids, i.e. tretinoin, retinol, adapelene
Gentle chemical peels containing a low
concentration of glycolic acid are generally considered safe in pregnancy.
Glycolic acid is an FDA Pregnancy Category N drug, i.e. it hasn’t been rated by
the American Food and Drug Administration.
An excellent treatment for acne in
pregnancy and during breastfeeding is dual-action Acleara Acne Clearing System
(Theraclear). Read more about this treatment under the “Adjunctive treatments”
section above.
If you have a darker skin
type, or if you tend to pick at your acne lesions, you’ll be more prone to
post-inflammatory hyperpigmentation (PIH) in pregnancy. It’s therefore very
important to be meticulous about using a high-factor, broad-spectrum sunscreen
that doesn’t clog pores. Go for non-comedogenic, dry-touch formulations.
Practical steps for managing acne
- Acne is treatable. If in doubt, consult your healthcare practitioner.
- Check whether the medication you’re currently using could be making your acne worse.
- If you have a strong family history of severe acne, your acne might start at a younger age and go on for longer. Consult your GP or dermatologist as soon as possible.
- If you’re a woman, and you experience any symptoms or signs of a hormonal imbalance, you should consult your GP or gynaecologist as soon as possible.
- A tinted, dry-touch sunscreen will help to reduce the visibility of any imperfections on the skin.
- Use “dry-touch” sunscreens for a matt finish that controls oil and shine.
- Choose moisturisers, sunscreens and make-up that display the words “oil-free” or “non-comedogenic” on their labels.
- Avoid heavy make-up and don’t use rich, greasy skin products.
- Don’t over-cleanse and don’t use harsh scrubs or exfoliators.
- Use a mild, foaming cleanser that has been formulated for oily, acne-prone skin.
