RHA Redensity

RHA Redensity has a light consistency that is perfect for smoothing out fine lipstick lines around the mouth.


RHA 2 is used on perioral lines around the mouth as well as to build volume in the lips, delivering pliable, natural-feeling enhancement.


RHA 3 is ideal for filling in moderate nasolabial folds and the lines and creases that form around the corners of the mouth.


The thicker consistency of RHA 4 helps to fill in deeper folds and creases, such as nasolabial folds and marionette lines extending vertically from the corners of the lips downward.

How does the RHA Collection work?

RHA Collection dermal fillers are designed to mimic natural hyaluronic acid within the skin. When injected, RHA Collection fillers not only add volume to the treatment area but also supplement the body’s existing hyaluronic acid RHA fillers are less chemically modified than traditional dermal fillers and thus allow for more natural movement of the product during animation and expression.

Benefits of RHA Collection Dermal Fillers

RHA Collection fillers are carefully manufactured to include fewer chemical modifications, allowing the hyaluronic acid component of each RHA formula to retain its purest state possible. RHA Collection fillers are unique in their ability to increase volume, treat static fine lines and wrinkles, and reduce the appearance of dynamic wrinkles and folds at once.

This special combination of characteristics also allows RHA Collection filler results to achieve more natural-looking results. RHA Collection fillers are exclusively available at the finest plastic surgery practices in the world. Tri Valley Plastic Surgery is Oakland's premier RHA Collection provider due to its well-founded reputation for excellence in patient care and procedure results.

What to Expect

When you arrive at Tri Valley Plastic Surgery for your exclusive treatment with the RHA Collection Oakland and Bay Area patient's skin will be cleansed and prepped for injection. A topical anesthetic may be used to reduce discomfort during the treatment (though the pain level associated with RHA filler injections is considered very minimal). Your RHA Collection dermal filler formula will be injected into all treatment areas per the treatment plan you and your injector have specified. Treatments with the RHA Collection typically take 30 minutes to an hour.



There is no downtime needed. Following RHA Collection dermal fillers Oakland patients may return to their regular activities immediately. Some patients may experience some mild swelling or bruising, though these issues typically resolve within one week.


While an increase in volume will be immediately visible in treatment areas, it typically takes two to four weeks for the filler to fully settle. In Oakland RHA Collection fillers are some of the longest-lasting dermal fillers, allowing for as much as 18 months before another treatment is needed.

What should I do and not do after my RHA injections?

After your RHA filler treatment, it is important to avoid heavy pressure on the treatment area. Intense heat (including hot tubs, saunas, tanning, and sunbathing) should be avoided as well. Exercise and alcohol consumption should be avoided for 24 hours after treatment.

What are the side effects of RHA fillers?

Injection site reactions may occur as a result of RHA filler injections and may include swelling, redness, itching, bruising, or infection. Swelling and bruising may be minimized with firm pressure and the application of ice packs before and/or after treatment. Infection is rare and easily treatable with antibiotics. Allergic reactions may also occur. Very rarely, the obstruction or compression of a blood vessel may lead to skin necrosis, but the risk can be minimized with proper technique.

No, RHA fillers are not permanent. However, they are among the longest-lasting dermal fillers on the market, filling in lipstick lines for up to a year and smoothing out dynamic wrinkles and creases for up to 15 months.
