| How
to treat breakouts. Considerations and topical treatments
There is no single best mode of treatment
for all acne lesions. Treatment is determined by many factors, including
the type of lesions present, duration of disease, past and present
response to various treatments, tendency for scarring and development
of acne spots. Current medical condition and medications especially
oral contraceptives, corticosteroids and antibiotics may affect
its treatment . Psychological factors may have great impact on the
way treating breakouts is pursued. Also patient's overall hygiene,
facial care, hair grooming and cosmetics must be considered. There
are two important points that acne patients should be aware of.
First, six to eight weeks of therapy may be required before improvement
is noted. Second, body lesions including back, chest and shoulder
lesions respond more slowly to various treatments than do those
on the face.
A rational approach to treat blemishes
could be to selectively target the treatment to factors involved
in development of acne and its pathogenesis. These approaches provide
a guidline for different treatments. First, prevention of comedones.
Second, reduction of sebum production. Third, preventing rupture
of comedones. Fourth, resolution of inflammation in acne lesions.
Fifth, preventing and correcting acne scars.
It is important to note that severe
form of acne must be consulted with a physician. Best treatments
for mild forms of acne such as comedones (white heads and black
heads), small pustules and scattered papules are topical desquamating
agents such as benzoyl peroxide. Among leading over-the-counter
treatments, benzoyl peroxide could be counted. Its antibacterial
efficacy is noteworthy with rapid suppression of Porpionibacterium
acnes. This suppressive effect is much faster compare with that
of antibiotics. In contrast to antibiotics, resident organisms do
not become resistant to this agent. This anti acne agent also demonstrates
anti-inflammatory effect due to a reduction of oxygen free radicals.
Its comedolytic effect is comparatively slight in contrast to other
topical agents used for acne. Contact allergy is quite rare with
it.
Comedolytic treatments suchas salicylic
acid, which could be used as alternative or adjunct to benzoyl peroxide.
This combination therapy maybe a treatment of choice for moderate
forms of acne. Salicylic acid comedolytic activity justifies its
therapeutic value in acne. Salicylic acid is also moderately effective
in destructing P.acnes. Application of alpha hydroxy acids may resolve
the comedones and prevent more severe acne.
Tretinoin (topical form of isotretinoin)is
among topical treatments especially when other forms of treatment
has failed. Tretinoin is prescribed drug and an skin irritant particularly
in liquid form. Cold climates and exposure to sunlight may cause
marked irritation. Retin-A (tretinoin) has an antikeratinization
effect and prevents comedone formation. Retin-A differs from benzoyl
peroxide and topical antibiotics in having no or a controversial
effect on P.acnes and causing no reduction in surface free fatty
acids. Tretinoin effectiveness against micorcomedones compare with
other treatments for acne provides a rationale for its use in most
forms of the disorder. This agent is particularly helpful in reduction
of non-inflammed lesions and comedones thereby indirectly reduces
the number of inflammed acne. This drug is a powerful exfoliant
and can cause tenderness, redness and scaling.
Treating blemishes with azelaic acid
is indicated in mild forms of acne such as acne comedonica. Sebum
production is not affected by this agent. At high concentration,
azelaic acid is bactericidal. However, the degree of bacterial suppression
is considerable less than with benzoyl peroxide. Azelaic acid has
also an anti-inflammatory effect to some degree by decreasing production
of reactive oxygen species. Mild sides effects such as redness and
scaling is associated with use of the drug.
One of the oldest treatments in history
of acne is sulfur. For a long time sulfur was the most common ingredient
in anti acne formulations. Sulfur while banishes inflammatory lesions,
simultaneously it incites formation of the comedones from which
new acne starts.
