Treatment for acne depends on how severe it is. It can take several monthsof treatment before acne symptoms improve.
The various treatments for acne are outlined below. You can also read a summary of the pros and cons of the treatments for acne , allowing you to compare your treatment options.
If you just have a few blackheads, whiteheads and spots, you should be able to treat them successfully with over-the-counter gels or creams (topical treatments) that contain benzoyl peroxide.
See your GP if your acne is more widespread, as you probably need prescription medication.
For example, if:
Prescription medications that can be used to treat acne include:
If you have severe acne, your GP can refer you to an expert in treating skin conditions (dermatologist).
For example, if you have:
A combination of antibiotic tablets and topical treatments is usually the first treatment option for severe acne. If this doesn't work, a medication calledisotretinoin may be prescribed.
Hormonal therapies or the combined oral contraceptive pill can also be effective in women who have acne. However, the progestogen-only pill or contraceptive implant can sometimes make acne worse.
Many of these treatments can take two to three months before they start to work. It's important to be patient and persist with a recommended treatment, even if there's no immediate effect.
Benzoyl peroxide works as an antiseptic to reduce the number of bacteria on the surface of the skin. It also helps to reduce the number of whiteheads and blackheads, and has an anti-inflammatory effect.
Benzoyl peroxide is usually available as a cream or gel. It's used either once or twice a day. It should be applied 20 minutes after washing to all of the parts of your face affected by acne.
It should be used sparingly, as too much can irritate your skin. It also makes your face more sensitive to sunlight, so avoid too much sun and ultraviolet (UV) light, or wear sun cream.
Benzoyl peroxide can have a bleaching effect, so avoid getting it on your hair orclothes.
Common side effects of benzoyl peroxide include:
Side effects are usually mild and should pass once the treatment has finished.
Most people need a six-week course of treatment to clear most or all of their acne. You may be advised to continue treatment less frequently to prevent acne returning.
Topical retinoids work by removing dead skin cells from the surface of the skin (exfoliating) which helpsto prevent them building up within hair follicles.
Tretinoin and adapalene are topical retinoids used to treat acne. They're available in a gel or cream and are usually applied once a day before you go to bed.
Apply to all the parts of your face affected by acne 20 minutes after washing your face.
It's important to apply topical retinoids sparingly and avoid excessive exposure to sunlight and UV.
Topical retinoids aren't suitable for use during pregnancy, as there's a risk they might cause birth defects.
The most common side effects of topical retinoids are mild irritation and stinging of the skin.
A six-week course is usually required, but you may be advised to continue using the medication less frequently after this.
Topical antibiotics help kill the bacteria on the skin that can infect plugged hair follicles. They're available as a lotion or gel that is applied once or twice a day.
A six- to eight-week course is usually recommended. After this, treatment is usually stopped, as there's a risk that the bacteria on your face could become resistant to the antibiotics. This could make your acne worse and cause additional infections.
Side effects are uncommon, but can include:
Azelaic acid is often used as an alternative treatment for acne if the side effects of benzoyl peroxide or topical retinoids are particularly irritating or painful.
Azelaic acid works by getting rid of dead skin and killing bacteria. It's availableas acream or gel and is usually applied twice a day (or once a day if your skin is particularly sensitive).
The medication doesn't make your skin sensitive to sunlight, so you don't have to avoid exposure to the sun.
You'll usually need to use azelaic acid for a month before your acne improves.
The side effects of azelaic acid are usually mild and include:
Antibiotic tablets (oral antibiotics) are usually used in combination with a topical treatment to treat more severe acne.
In most cases, a class of antibiotics called tetracyclines is prescribed, unless you're pregnant or breastfeeding.
Pregnant or breastfeeding women are usually advised to take an antibiotic called erythromycin, which is known to be safer to use.
It usually takes about six weeks before you notice an improvement in your acne.
Depending on how well you react to the treatment, a course of oral antibiotics can last four to six months.
Tetracyclines can make your skin sensitive to sunlight and UV light, and can also make the oral contraceptive pill less effective during the first few weeks of treatment.
You'll need to use an alternative method of contraception, such as condoms, during this time.
Hormonal therapies can often benefit women with acne, especially if the acne flares up around periods or is associated with hormonal conditions such as polycystic ovary syndrome.
If you don't already use it, your GP may recommend the combined oral contraceptive pill , even if you're not sexually active. This combined pill can often help improve acne in women, but may take up to a year before the full benefits are seen.
Co-cyprindiol is a hormonal treatment that can be used for more severe acne that doesn't respond to antibiotics. It helps to reduce the production of sebum.
You'll probably have to use co-cyprindiol for two to six months before you notice a significant improvement in your acne.
There's a small risk that women taking co-cyprindiol may develop breast cancer in later life.
For example, out of a group of 10,000 women who haven't taken co-cyprindiol, you would expect 16 of them to develop breast cancer by the time they were 35. This figure rises to 17 or 18 for women who were treated with co-cyprindiol for at least five years in their early twenties.
There's also a very small chance of co-cyprindiol causing a blood clot . The risk is estimated to be around 1 in 2,500 in any given year.
It's not thought to be safe to take co-cyprindiol if you're pregnant or breastfeeding. Women may need to have a pregnancy test before treatment can begin.
Other side effects of co-cyprindiol include:
Isotretinoinhas a number of beneficial effects:
However, the drug can also cause a wide range of side effects. It's only recommended for severe cases of acne that haven't responded to other treatments.
Because of the risk of side effects, isotretinoin can only be prescribed by a specially trained GP or adermatologist.
Isotretinoin is taken as atablet. Most people take a four- to six-month course. Your acne may get worse during the first 7 to 10 days of treatment. However, this is normal and soon settles.
Common side effects of isotretinoin include:
Rarer side effects of isotretinoin include:
Because of the risk of these rarer side effects, you'll need a blood test before and during treatment.
Isotretinoin will damage an unborn baby. If you're a woman of childbearing age:
You'll be asked to sign a form confirming that you understand the risk of birth defects and are willing to use contraceptives to prevent this risk, even if you're not currently sexually active.
If you think you may have become pregnant when taking isotretinoin, contact your dermatologist immediately.
Isotretinoin is also not suitable if you're breastfeeding.
There have been reports of people experiencing mood changes while taking isotretinoin. There's no evidence that these mood changes were the result of the medication.
However, as a precaution, contact your doctor immediately if you feel depressed or anxious, have feelings of aggression or suicidal thoughts.
Several treatments for acne don't involve medication.
However, these treatments may not work and can't be routinely recommended.
Despite being one of the most wide spread skin conditions, acne is also one of the most poorly understood. There are many myths and misconceptions about it: "Acne is caused by a poor diet". "Acne is caused by having dirty skin and poor hygiene". "Squeezing blackheads, whiteheads and spots is the best way to get rid of acne"
Acne is a common skin condition that affects most people at some point. It causes spots, oily skin and sometimes skin that's hot or painful to touch. Acne is most common in girls from the ages of 14to 17, and in boys from the ages of 16to 19. Most people have acne on and off for several years before their symptoms start to improve as they get older.
Teenage acne is thought to be triggered by increased levels of a hormone called testosterone, which occurs during puberty. More than 80% of cases of adult acne occur in women. It's thought that many cases of adult acne arecaused by the changes in hormone levels that many women have at certain times.
Your GP will be able diagnosis acne by looking at your skin. This will involve examining your face, chest and back for the different types of spot. How many spots you have and how painful and inflamed they are will help determine how severe your acne is. This is important in planning your treatment.
Treatment for acne depends on how severe it is. It can take several months of treatment before acne symptoms improve. If you just have a few blackheads, whiteheads and spots, you should be able to treat them successfully with over-the-counter gels or creams (topical treatments) that contain benzoyl peroxide. See your GP if your acne is more widespread, as you probably need prescription medication.
Acne scarring can sometimes develop as a complication of acne. This is more common when the most serious types of spots burst and damage nearby skin. Once subscision has been completed, additional treatment, such as laser treatment and dermabrasion, can be used to further improve the appearance of the scar.
The self-help techniques that may be useful: Don't wash affected areas of skin more than twice a day. Frequent washing can irritate the skin and make symptoms worse. Wash the affected area with a mild soap or cleanser and lukewarm water. Very hot or cold water can make acne worse. Don't try to "clean out" blackheads or squeeze spots. This can make them worse and cause permanent scarring . Avoid using too much make-up and cosmetics.
