Physical Procedures for Treating Acne
Dermatologists occasionally use procedures
to help clear acne. These methods, which are described below, should be
performed by a dermatologist or other health care practitioner. Trying
these at home can lead to infection, worsening of the acne and scarring.
Chemical Peels
Light chemical peels of glycolic acid and other chemical agents are used
by dermatologists to loosen blackheads and decrease acne
papules.
The Sun, Sun Lamps and
Tanning Booths
These should NOT be used to treat acne because none have proven
effective in treating acne and all expose the skin to harmful ultraviolet
(UV) light. Exposure to UV light increases the risk of developing melanoma
and other types of skin cancer. |
Comedo Extraction
Sometimes removing comedones proves beneficial. To extract whiteheads
and blackheads, dermatologists use a sterile pen-sized device. This
procedure should only be performed by a dermatologist or other medical
professional. Patients’ attempts to extract comedones and drain cysts by
squeezing or picking, can lead to worsening of the acne, scarring and
infection. Tissue injured by squeezing or picking can become infected by
staphylococci, streptococci and other bacteria.
Drainage and Surgical Extraction
Some large cysts do not respond to medication and may require drainage
and extraction. Drainage and extraction, which is also called “acne
surgery,” reduces the pain associated with these cysts and decreases the
likelihood of scarring. It should not be performed by patients.
Patients’ attempts to drain cysts or extract
comedones by squeezing or
picking, can lead to infection, worsening of the acne and scarring.
Dermatologists are trained in the proper technique and perform “acne
surgery” under sterile conditions.
Phototherapy (Laser and Light
Treatments)
Several laser and light treatments are available to treat acne. Some of
these laser and light treatments target only one factor that causes
acne—P. acnes. For many patients, this is not a comprehensive treatment
for resolving their acne. A dermatologist can determine if laser or
light treatment is appropriate for a patient.
Advantages to laser and light treatments
include not having to remember to apply or take any medication and the
ability to treat hard-to-reach areas, such as the back. However, laser
and light treatments can be quite expensive, and long-term effectiveness
has not been proven.
Over the last several years, laser
technology has also assumed an increasingly important role in the
treatment of acne scars.
Anyone considering laser or light therapy
should consult a dermatologist experienced in providing the therapy.
Don’t be afraid to ask questions about the physician’s experience and
qualifications.
