Plot hole: Miranda Wilson states that after the accident on the movie set left her face disfigured, she hid in the catacombs by the bridge and almost died from her condition until Quentin Beck found her after he was released from prison. Beck is the one that caused the accident in the first place, so even if he only spent a month in prison, Miranda Wilson would have died from starvation or malnutrition - if not infection from her untreated facial disfigurement - long before Beck could have been released from prison and found her.
Answer: I believe it was just a way to try and show the suit is "oily" or reflective. It also helps define the character's features since otherwise, he'd just be a flat black color. It's similar to how the black suit Spidey had blue outlines. (I don't know why they chose a pink/red color... maybe because red is associated with power/fire/war, so it's a more "evil" color?)
