I can say it yes. Doxycycline can give much improvement
against acne. First, it kills the bacteria inside your body. Second, it dries
up swollen acne papules. And third, it will prevent P. Acnes Bacterium from
forming back.
However, Doxycycline can make your skin dry and sensitive to
the sun. So, you should use a non-comedogenic and non-greasy moisturizer to
keep your skin hydrated. In addition, a better sunscreen with high level of SPF
should be use to prevent sunburn.
You should also take into consideration that taking any
antibiotic like Doxycycline without your doctor’s prescription can be a life
threatening. Although Doxycycline can give you good results, it has side effects in rare cases.
