Acne. OrthoTriCyclen and Yaz (drospirenone and ethinyl estradiol) are 2 brands that are indicated in acne. Bellara is not particularly useful in this regard.
Belara. I believe that you're referring to Belara which is not available in the States. The manufacturer states that it might have skin benefits: http://www. Belara.

Yes. Generally low estrogen bcp's are helpful for acne.
Multiple ways. Research shows that these pills can clear acne by slowing down overactive oil glands in the skin. Sometimes, bc pills are used along with a drug called spironolactone to treat acne in adult females. This medication lowers levels of the hormone androgen in the body. Androgen stimulates skin's oil glands. Additionally, the estrogen helps bind testosterone and decrease its effect on the skin/glands.
