Hi K.. I am 37 years old and have been suffering from severe adult cystic acne for quite a few years now. I have tried all of the products. My bathroom is filled with Proactiv, Murad, soy products, creams, lotions, medications.... I have visited the dermatologist WEEKLY to have Cortisone shots in my face, directly on the cyst. Yuck and Ow! I have taken every antibiotic out there with absolutely no results.
I was also on Accutane in my 20's, but I fell into the 5% of people who's acne came back. If your problem is hormonal all of the over the counter products out there will probably work for you for long. I know that at first Proactiv was wonderful and I was ecstatic. That lasted about two months and it lost it's magic for me. Same for Murad, Neutrogena...
My problem is definitely hormonal. Acne that is showing up around the chin and mouth is typically hormonal for a woman your age (according to my dermatologist and OBGYN). The only thing that worked wonders for me was going on the Pill. At first I tried Yaz because it actually is advertised as helping acne. It did not help and in fact made it worse so I switched to a different Pill called Levora. I am not saying that this Pill is the one for you. I think it is very individual, but if you haven't tried using the Pill to help cure your acne give it a shot and see what happens.
My doctore also prescribed Benzaclyn and Differen 0.3%. They are extremely strong topical lotions that really work great as well in combination with the Pill.
Try speaking to your dermatologist about this. I am actually shocked that they haven't recommended it or maybe they did already. All I know is that within a week to two weeks my severe acne cleared up completely. I recently was off the pill for a week and immediately my acne returned so I know for sure that the Pill is the way to go for me.
Good luck and feel free to contact me if you have any questions.
Peace,
J.
