Dermal Fillers
What Are Dermal Fillers and How Do They Work?
Dermal fillers are injectable treatments that restore volume, smooth deeper lines, and enhance facial contours. At Solina, we use the RHA Collection of fillers — a line of resilient hyaluronic acid fillers specifically designed to adapt to your facial movements for results that look and feel completely natural, even in areas of high expression and motion.
Unlike traditional fillers, RHA fillers are engineered to mimic the natural hyaluronic acid found in your skin, allowing them to flex and move with your face rather than appearing stiff or static. Every treatment begins with a thorough consultation and facial assessment so we can understand your goals and build a plan that enhances your features while keeping everything balanced and proportional.
The RHA Collection — Fillers That Move With You
We offer the full RHA Collection, including RHA2, RHA3, RHA4, and Redensity, each designed for a specific type of concern and area of the face.
RHA2 is best suited for fine lines and superficial areas where a lighter touch is needed. RHA3 works well for moderate to deep lines and areas like the nasolabial folds. RHA4 is ideal for deeper volume loss and structural support in areas like the cheeks and jawline. Redensity is specifically formulated for the under-eye area, delivering subtle hydration and correction without the heaviness that some fillers can produce in that delicate zone.
Your provider will recommend the right product or combination of products based on your facial anatomy and what you are hoping to achieve. The goal is always natural-looking results that enhance what is already there — never overdone, never obvious.

Here is why so many clients choose RHA dermal fillers at Solina.

Does getting dermal fillers hurt?
Most clients find the treatment very manageable. A topical numbing cream is applied beforehand, and RHA fillers also contain lidocaine to keep discomfort minimal throughout the procedure.
How long do RHA fillers last?
RHA fillers typically last between 12 and 18 months, though individual results vary depending on the product used, the area treated, and your metabolism.
Is there any downtime after dermal fillers?
Most clients experience mild swelling or bruising that settles within a few days. You can return to normal activities right away, though we recommend avoiding strenuous exercise for 24 hours.
What is the difference between RHA2, RHA3, RHA4, and Redensity?
Each product in the RHA line is formulated for a different level of correction. RHA2 is for finer, more superficial concerns. RHA3 handles moderate lines and folds. RHA4 provides deeper volume and structure. Redensity is specifically designed for the delicate under-eye area.
