Almost all cases of acne can be effectively treated. The goal of treatment is to promote the healing of existing acne lesions, stopping new lesions from forming, and preventing the formation of acne scars.
Acne treatment aims to control one or more of the underlying causes of acne. For instance, topical retinoids unclog sebaceous glands and keep pores open, while antibiotics are used to fight the P. acnes bacteria. Isotretinoin (Accutane) and hormonal agents, such as birth control pills, are used to reduce sebum (oil) production.
Your doctor will recommend an acne treatment plan based on these factors:
Whatever your treatment plan, it is important that you give it enough time to work.
This may mean waiting 6 to 8 weeks to see results. While the older acne lesions are healing, the medication is hard at work keeping new lesions from forming.
Staying on your medication is the most important step to getting acne under control.
Many people will first attempt to treat their acne with an over-the-counter acne medication. Many brands of acne treatment share the same active ingredients. For instance, benzoyl peroxide is the active ingredient of both ProActiv™ and Clearasil™.
However, even some cases of mild acne may require prescription-strength medications for effective treatment. If no improvement is seen after 6 to 8 weeks of using a non-prescription medication, see your doctor about starting other medications. Relying on an ineffective treatment simply means enduring acne for weeks longer than necessary and increases the chances of developing permanent acne scars.
Benzoyl peroxide was one of the first medications found to be effective in treating mild acne and has been used safely for decades. It is found in many over-the-counter formulas, as well as in combination with prescription medications. Benzoyl peroxide is available in different concentrations. Its primary side effect is dry skin and higher concentrations are more likely to irritate the skin.
Benzoyl peroxide may be used in combination with other prescription acne medications. For instance, your doctor may recommend that benzoyl peroxide be used along with an oral or topical antibiotic.
These medications have some mild ability to break down whiteheads and blackheads and are found in many non-prescription acne medications. Like benzoyl peroxide, salicylic acid must be used continuously. Once these medications are stopped, acne lesions are likely to reappear.
Over-the-counter products labeled "herbal," "organic" or "natural" are marketed as acne treatments but their effectiveness has rarely been tested in clinical trials. The value of these alternative acne treatments is not known.
Topical retinoids are among the most effective and commonly used prescription acne medications. Topical retinoids are unique in their ability to unclog swollen pores. They may be used alone for mild acne or combined with other medications for moderate to severe acne.
Different topical retinoids are found in a variety of branded acne medications, include:
Antibiotics applied to the skin, such as clindamycin and erythromycin, kill the P. acnes bacteria that leads to inflammation.
Antibiotics, such as tetracycline, doxycycline, and minocycline, may be prescribed for oral use. This allows the medication to reach bacteria in the deep layers of the dermis. They are also prescribed for their ability to reduce skin inflammation.
Dapsone is a medication that that may be applied to the skin to reduce the inflammation of acne.
For women who experience hormonally triggered acne, birth control pills may be prescribed to reduce sebum production.
Isotretinoin remains the most effective treatment for severe acne or acne that does not respond to other treatments. Isotretinoin treats all causes of acne: excess sebum, clogged pores, bacterial overgrowth, and inflammation. Most patients take the medicine for periods of 15 to 20 weeks that may be repeated if necessary. Treatment requires monthly office visits, monthly lab tests, and strict contraception. It is critical that women of childbearing age do not get pregnant while taking isotretinoin because of the serious risk of birth defects. The iPledge program was developed to reduce the likelihood of birth defects and other side effects.
Some drugs used for other medical conditions are known to reduce androgen levels, such as spironolactone (Aldactone). These may be used in some cases of acne.
Many of these acne medications have side effects, such as burning, redness, and irritation. With some medicines, such as topical retinoids, these side effects usually decrease or go away after the medicine is used for a period of time. Tell your doctor if side effects are severe or don't go away.
While the older acne lesions are healing, the medication is hard at work keeping new acne lesions from forming. Staying on your acne medication is the most important step to getting acne under control.
For persistent acne lesions that are inflamed or unresponsive to medications, some doctors recommend additional methods, including extraction, photodynamic therapy (PDT), or corticosteroid injections.
It is important to talk to your doctor about the best acne treatment for you.
Ongoing use of your acne medicine may be required for several months, even after the initial acne lesions cleared up, to keep acne under control.
