At-Home Treatment of Acne
Many of the over-the-counter acne medications on the market today rely on
similar chemical-based keratolytic agents (substances that act to unclog pores)
such as benzoyl peroxide or salicylic acid. Benzoyl peroxide, resorcinol,
salicylic acid, and sulfur are the most common topical OTC medicines used to
treat acne. Each can be purchased over the counter, and each works differently.
Benzoyl peroxide is best at killing bacteria and may reduce oil production.
Resorcinol, salicylic acid, and sulfur help break down blackheads and
whiteheads. Salicylic acid also helps cut down the shedding of cells lining the
follicles of the oil glands. Topical OTC medications are available in many
forms, such as gel, lotion, cream, soap, or pad. Patients must keep in mind that
it can take 8 weeks or more before they notice their skin looks and feels
better.
There are problems with over the counter acne medications. In some
patients, OTC acne medicines may cause side effects such as skin irritation,
burning, or redness. Benzoyl peroxide can cause skin irritation and drying.
Salicylic acid is also an irritant and can cause erythema and peeling. When
properly used, these products may contribute to a hygiene regimen that will
reduce the incidence and severity of acne in some individuals; however,
over-the-counter acne medications do little to impact the blemishes that
inevitably occur. The problems with traditional at home treatment of acne has
led many people to seek prescription medications.
Prescription Acne
Medicines
Systemic Treatments/Topical Preparations
A variety of prescription medicine methods are used to prevent and treat
acne: pill, topical, and injectables. Topical therapies such as Retin-A account
for roughly half of the US prescription
acne medicine market. Systemic therapies such as Isotretinoin (commonly called
Accutane) make up the other half of this market (Micrologix BioTech 2003). In
general, mild to moderate acne cases are treated with topical medications, with
more severe acne cases being treated with systemic or a combination of topical
and systemic therapies. Antibiotics taken by mouth such as tetracycline,
doxycycline, minocycline or erythromycin are often prescribed for moderate to
severe cases, especially when there is a significant amount of acne on the back
or chest. Antibiotic treatment is used to kill the bacteria P. acnes that cause
acne flares. Prescription oral and topical medicines are sometimes
combined.
Problems exist with most of these
acne treatment options. Accutane has been linked to serious side effects.
Antibiotics are not as useful as they once were as P. acnes has developed
resistance to them. Antibiotic resistance in P. acnes strains has been reported
worldwide, and the incidence of antibiotic resistant P. acnes has increased
dramatically from 20% in 1978 to 60% in 1996 (Guttman; Micrologix Biotech 2002).
In addition, the use of antibiotics has also been linked to serious side
effects.
Recently Introduced Prescription
Acne Therapies
Doctors sometimes use other
procedures in addition to drug therapy to treat acne. For example, the doctor
physically remove the patient's comedones during office visits. Some doctors
inject cortisone directly into lesions to help reduce the size and pain of
inflamed cysts and nodules.
Recently,
prescription acne therapies have been introduced to the dermatology community
involving either ultraviolet light or laser light. While these therapies are
making some inroads to the acne treatment market, they are also receiving
publicity for the novelty of their approaches. Such therapies not only require
medical supervision, but they involve potentially harmful radiation, substantial
investment in equipment and very high treatment costs. Finally, none of these
therapies have been shown to be as effective at treating blemishes as Zeno Acne Clearing
