Retin A can help but it's very drying. You asked about laser treatment. My sister recently got laser done for her acne/blemishes and Alhumdolillah it has turned out well for her. The dermatologist told her that she wont be breaking out in a long time and the next time that she MIGHT have a serious breakout would be if she becomes pregnant in the future, as pregnacny causes hormons fluctuations.
She paid 100 for the first laser session and that 180 for the second and final session. She said it didn't hurt at all and that the laser just feels warm.
The dermatologist also got rid of some light facial hair with the laser for her. And my sis told me that laser shrinks the oil glands so that you break out less in the future.
I'm currenly using Obagi products for my acne because they contain hydroquinone, which helps to fade spots. If things don't get better, I might look into laser treatment as well. The only thing that concerns me is that just like you I also break out when I get my period, so it's probably hormonal acne and I'll have ask the dermatologist if laser can prevent PMS related breakouts effectively.
If you're looking for a treatment that will provide long term results, then it's best to consult a dermatologist who can assess your skin and recommend the best options for effective treatment.
