I have good skin for a 53-year-old, and in the past, have had Botox around eyes and forehead, and filler in nasolabial folds. With the downturn in the economy I am on a tight budget, so I'm trying to determine the best course of action without wasting money. Which facial skin tightening treatment should I have? I have used Prevage (prescription) before and am now trying Olay Regenerist. Which do you think is more effective?
