| No. Having vaginal intercourse does not cure acne. Many people believe this myth, though, and many claim that it has happened to them. And there are good reasons that it may have seemed to.
As we know, acne is a common side effect of puberty. When all of the hormonal changes of puberty end, so does acne — for most people. The age at which the hormonal changes are complete varies, but this stage of maturity is usually reached by the time a young person turns 17 or 18. This is also when many people have their first intercourse.
Other misunderstood evidence for this myth concerns the pill and other combined hormone methods of birth control — the patch or the ring: Many young women use them when they start to have intercourse. Not only is it likely that they are mature enough for their acne to naturally go away, but combined hormone methods actually help clear up acne conditions.
These two coincidences have reinforced the myth that having sex is a cure for acne. But they're just coincidences. |
