Diane 35 affects testosteron receptors in your skin.Ones with oily,acne prone skin have more of those receptors then ones with dry or normal skin.When testosteron bind to receptor,skin starts to produce sebum which becomes an acne.The pill blocks receptors therefore glands do not produce sebum because testosteron can't be bind.If you have a normal hormone levels (you probably have if you have regular menstruation cycle ) there are no side effects as nausea,weight gain, emotional affect as depression,mood swings, loss of libido.Those side effects come from higher level of estrogen in your body,plus more estrogen you take from the pill.
Diane 35 work perfectly for me,because my first problem are testosteron receptors (not hormon levels).No weight gain, l got rid of new acne in 3 weeks,shorter,less painfull and bloody periods and I have bigger boobs (praise the estrogen :D).
To girls with severe side effects I suggest test for hormone levels,and changing the therapy colsulting the dermatologist or gynecologist.
Btw Avѐne TriAcnaél cream for local use works great with Diane 35 acne therapy ;)
