CosmeticMD also lied when he/she said RVNC stopped claiming a 6 month duration. I don't believe they ever claimed 6 months, rather they stated lasting longer. The new Daxxify lite vs Daxxify version makes it clear RVNC is making it clear that you can choose a Daxxify dosage that provides longer lasting effects.
I think you’re both wrong. See the Daxxify website.
Long Lasting
DAXXIFY® may last up to twice as long as conventional frown line treatments for some.*
*Conventional frown line treatments last 3-4 months. At least 50% of patients in clinical studies had no or minor frown lines 6 months after treatment with DAXXIFY®. In other safety studies, between 5% and 17% of patients still had noticeable improvement 9 months later
