NAC and saw palmetto questions

Im 23 years old and getting very tired of the shaving routine, especially now that I am dating and my partner notices the stubble (very embarrasing) I've tried facial creams, but my face breaks out horribly, I've waxed and plucked but its painful and the regrowth is evident before its time to re-wax. I stumbled on this site and saw information on NAC and saw palmetto. If anyone could give me more information on either of these that would be great... especially if they work. My concern is long term health effects and also their interaction with birth control pills, which i take to regulate my cycle. Like I said any info would be great! thanks Tweet
