RHA Collection

The RHA® Collection is the first hyaluronic acid filler formulated to adapt to your facial movements. Created through a gentle manufacturing process that preserves the natural structure of hyaluronic acid, these fillers more closely mimic the hyaluronic acid found in your own skin—helping maintain moisture, volume, and support. Because natural hyaluronic acid decreases with age, the RHA® Collection is designed to replenish what’s lost while moving seamlessly with your expressions for a soft, natural look both at rest and in motion.

RHA® Collection Products:

• RHA® Redensity: Targets moderate to severe wrinkles around the lips and mouth
• RHA® 2: Treats moderate dynamic wrinkles and fine lines, especially around the mouth
• RHA® 3: Softens moderate to severe facial wrinkles and folds, including smile lines
• RHA® 4: Adds volume and definition to facial contours and treats deeper wrinkles and folds

Dynamic wrinkles form in areas that move repeatedly—like when you frown, squint, laugh, or talk. Traditional fillers can sometimes look stiff during movement, but the RHA® Collection is designed to stretch, flex, and recover naturally, giving you a more realistic, expressive result.
