Bee venom is on the rise as a new cosmetic ingredient, rejuvenating skin as an alternative to injections of Botox®, is now proven to stop the growth of acne. It's antibacterial and anti-inflammatory properties make it a promising new compound...
Effects of
cosmetics containing purified honeybee (Apis mellifera L.) venom on acne
vulgaris
J Integr Med, 2013, Sept.
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%.
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.
