When will I see results and how long will they last?

Dermal filler injection results are immediate. The results from the RHA® Collection of fillers can typically last up to 15 months in wrinkles and folds and 1 year in lipstick lines. The RHA® Collection is widely studied. The clinical effectiveness and safety of RHA® 2, RHA® 3, and RHA® 4 were shown in two 15-month studies for wrinkles and folds. The clinical effectiveness and safety of RHA® 3 in the lips was shown in a 12-month study in which nearly 1/2 of participants had increased lip fullness at 1 year. The clinical effectiveness and safety of RHA Redensity™ were shown in a 12-month study for lipstick lines—in which 2/3 of participants still had lipstick-line improvement at 12 months.
