Objective To provide theoretical proofs for facial acne treatment by observing the influence of lavender essential oil and aqueous extract of aloe on main flora of facial acne(Propionibacterium acnes and Staphylococcus epidermidis) in vitro.Methods Serial dilution method was adopted to dilute lavender essential oil and aquedous extract of aloe.Paper disc method was performed to observe the effects of different concentrations of lavender essential oil and aquedous extract of aloe on facial flora.The effect of bacteriostasis was represented by the area of inhibition zone.Growth curve was plotted to detect the influence on bacteria growth.Results Lavender essential oil showed a stronger inhibitory activity against Propionibacterium acnes than Staphylococcus epidermidis(P0.05);Aloe vera and aloe arborescens mill did not seem to have inhibitory effect on Propionibacterium acnes(P0.05);Aloe vera had a weak inhibitory effect on Staphylococcus epidermidis(P0.05),while Aloe arborescens Mill showed a positive growth-promoting effect on Staphylococcus epidermidis.Conclusion The influences of lavender essential oil and aqueous extract of aloe on main flora of facial acne(Staphylococcus epidermidis and Propionibacterium acnes) are different.Application of lavender essential oil combined with aloe might help to improve facial acne symptoms through modulating facial microecological balance.
