It's been my experience that 20 minutes doesn't really produce results so I'd love to know what the 60 minute upgrade costs? Thanks!

Hi Nicole, 20 minutes works for some people but in our experience for the deepest whitenings you definitely want to be exposed to peroxide and the laser system for longer sessions. We like to offer our Groupon clients a special discount savings. The upgrade is only $40 per additional 20 minute session. Between the Groupon price of $49 and if you upgrade to a 60 minute session you would be only spending $129 on a 60 minute session that is valued at $300 so it is an exceptional offer!!! Hope this answer helps.
