RHA® 4 Treatment
There comes a time when soft creams and serums are no longer enough to restore what age has quietly taken away—volume, structure, and definition. When you begin to see your features losing contour or deep lines starting to settle in, it can feel like your reflection no longer matches how strong and confident you feel inside. At PRICK’D Med Spa in St. Louis, MO, we offer RHA® 4, the most robust filler in the RHA® Collection, specifically designed to support and lift the deepest dynamic wrinkles and facial folds. Whether you’re looking to recontour your cheeks, define your jawline, or smooth out deep smile lines, RHA® 4 delivers resilient results that move with your face—so you look refreshed, expressive, and entirely natural. Book your consultation today and take the next step toward sculpted, youthful confidence.

How Does RHA® 4 Work?
RHA® 4 is a dynamic hyaluronic acid filler, expertly crafted to correct deeper lines and restore structure to areas of the face that experience constant movement. It’s perfect for lifting and contouring more severe facial wrinkles and folds while maintaining a natural, flexible finish. The formulation allows it to stretch and move with your expressions, making it especially effective for areas like the lower face, jawline, and cheeks.
At PRICK’D Med Spa, your treatment begins with a thorough consultation. Our aesthetic experts assess your facial anatomy, skin quality, and personal goals before creating a treatment plan tailored to you. During the procedure, RHA® 4 is injected into targeted areas using a fine needle or cannula. Most clients describe the experience as quick and tolerable.
You’ll see immediate volume restoration and lift, with continued improvement as the filler settles and hydrates the skin. Because of its resilient formula, RHA® 4 remains soft and mobile under the skin—never stiff or unnatural—making it ideal for high-movement areas that still need strong support.
RHA® 4 Pre & Post-Care Instructions
A smooth experience and long-lasting results can be achieved by following the correct pre- and post-treatment instructions.
Pre-Care Instructions:
- Avoid alcohol and blood-thinning medications such as aspirin, ibuprofen, or fish oil for 24 hours prior.
- Arrive with a clean, makeup-free face for the best treatment prep.
- Let your provider know about any recent dental work or active skin conditions near the treatment area.
Post-Care Instructions:
- Apply a cold compress if needed to reduce minor swelling or bruising.
- Treated areas should not be touched or massaged for 24 hours to settle the filler properly.
- Do not exercise vigorously or expose your face to intense heat (like saunas or steam rooms) for 24 to 48 hours.
- Sleep with your head elevated for the first night to minimize swelling.
- Apply broad-spectrum SPF daily to protect your skin and prolong results.
By following these steps, you’ll help your results look smooth and even and last longer.
