Effects of cosmetics containing purified honeybee (Apis
mellifera L.) venom on acne vulgaris
J Integr Med, 2013 Sep;11(5):320-6
OBJECTIVE:
Acne vulgaris is a chronic dermatologic problem with
multiple factors involved in its pathogenesis. Alternative solutions to acne
treatment were instigated by antibiotic resistance despite of its extensive
use. Purified bee venom (PBV) has been proposed as a promising candidate for
that purpose. The present study was designed to confirm the antibacterial effect
of PBV and access the efficacy of cosmetics containing PBV in subjects with
acne vulgaris.
METHODS:
The skin bacterium Propionibacterium acnes was incubated
with PBV at various concentrations and bacterial growth was evaluated using the
colony forming unit (CFU) assay. The mechanism of PBV employed in killing P.
acnes was examined by scanning electron microscopy (SEM) and transmission
electron microscopy (TEM). In addition, a total of 12 subjects were randomized
in a double-blind, controlled trial to receive either cosmetics containing PBV
or cosmetics without PBV for two weeks. Evaluations included lesion counts and
skin microorganism.
RESULTS:
PBV exhibited antimicrobial activity in a
concentration-dependent manner, reducing the number of P. acnes CFU by
approximately 6 logs at a concentration of 0.5 mg. When PBV concentration was
higher than 1.0 mg, no P. acnes colonies were spotted on an agar. TEM and SEM
of untreated P. acnes illustrated the normal pleomorphic structure, whereas the
PBV-treated bacterium lost the integrity of surface architecture. Significant
difference (P=0.027) in the grading levels based on numbers of lesion counts
for inflammatory and noninflammatory was observed in favour of the PBV group
compared with the control group. In terms of average decrement of skin
microorganism, subjects receiving cosmetics containing PBV experienced a
significant 57.5% decrease of adenosine triphosphate levels, whereas
participants receiving cosmetics without PBV experienced a nonsignificant decrease
of 4.7%.
CONCLUSION:
These results show that the in vitro actions of
antimicrobial activity of PBV were translated in vivo. Cosmetics containing PBV
provided a certain degree of efficacy in terms of lesion counts and skin
microorganism concentration compared with cosmetics without PBV in subjects
with acne vulgaris. PBV may be a good candidate compound for developing
therapeutic drug for the treatment of acne vulgaris.
