Compared to certain other plants, peace lilies don't need to be pruned very frequently. However, if, for whatever reason, one or more of your lily's limbs or leaves become brown or wilted, you may want to prune the leaves to keep the plant from wasting energy on the dying appendage.
Accutane is a retinoid, and not related to anti-biotics so the side effects are different. However, the list of potential rare side effects of accutane is long and includes headaches, nausea, muscle pain and depression.
Accutane did not work for me. I was on it for eight months hoping it would clear my face but it didn't. It works for a large majority of people but i guess i was a rarity. dried the hell out of my skin and i had all those other symptoms that everyone has heard about.
