Yes, RHA (Resilient Hyaluronic Acid) fillers are FDA approved for smoothing dynamic wrinkles and facial folds. The RHA Collection—developed by Revance Therapeutics—represents a newer category of hyaluronic acid fillers designed specifically to move with facial expressions rather than against them, making them particularly effective for dynamic wrinkles.
The RHA Collection Overview
The RHA Collection includes three products:
RHA 2: Designed for fine lines and superficial wrinkles
RHA 3: Formulated for moderate wrinkles and folds
RHA 4: Intended for deeper folds and volume restoration
Each product has a different cross-linking structure that allows it to flex and adapt to natural facial movement—a key differentiator from traditional, more rigid HA fillers.
FDA Approval Status
RHA 2, RHA 3, and RHA 4 all carry FDA approval for use in smoothing facial wrinkles and folds. This approval means they meet safety and efficacy standards for aesthetic use. However, as with all fillers, verify current labeling and approved indications with the manufacturer or your regulatory compliance team, as product information can be updated.
RHA fillers are FDA approved and designed to move with facial expressions, making them ideal for dynamic wrinkles.
Why Dynamic Wrinkles Matter for Your Practice
Many patients seek treatment specifically for dynamic wrinkles—lines that appear when smiling, frowning, or expressing emotion. Traditional fillers can sometimes look stiff or unnatural in these areas because they don't accommodate movement. RHA fillers' flexibility appeals to patients wanting natural-looking results, which can be a strong marketing angle for your practice.
Practical Considerations for Owners
Stock and pricing vary by distributor; confirm availability and cost with your supplier
Training and certification may be recommended before injecting a new product line
Patient education about the "movement-friendly" benefit can justify premium pricing
Consider adding RHA to your menu if you're seeing demand for dynamic wrinkle solutions
RHA fillers represent an evolution in HA technology, and their FDA approval makes them a legitimate option for expanding your treatment offerings.
