Everything You Need To Know About The Newest Filler, RHA

Filler is one of the most popular and sought out aesthetic treatments. With the ability to restore volume, contour the face, and plump lips, filler has earned its reputation as a jack-of-all-trades must-have treatment. 

Most dermal filler is made up primarily of hyaluronic acid (HA), a substance naturally found in the body that has the ability to store and retain moisture which gives skin a plump, hydrated look. As we age, our bodies lose hyaluronic acid: cells can no longer hold as much and collagen begins to deplete, leading to loss of skin elasticity. Filler —  which works by smoothing out wrinkles in the treated area or by literally filling in the skin to plump or shape —  can restore lost volume or add some extra in just one short appointment. 

While we offer multiple types of filler, one of our recent obsessions is RHA filler, a dynamic newcomer created by European doctors in 2015. 

RHA is notable because of its pure ingredient list with few chemical modifications. This allows for gentle results that adapt to the natural movement of your face for results that look, feel and blend like your own skin. Not only that, RHA also has the ability to treat a range of skin types, ages, and conditions — proving its prowess in the filler field. 

One of the distinguishing features of RHA is that it isn’t one-size-fits-all. There are three different RHA formulas titled 2,3,4 that are tailored to your precise needs. 

RHA Level 2

The lightest of the bunch, RHA 2 is ideal for superficial smoothing, addressing cheek lines, smile lines, and best suited for those seeking lip augmentation. To the untrained eye, RHA 2 is closest in makeup to other brand name fillers on the market. 

RHA Level 3

RHA 3 is for mid-to-deep injection. It can be used to treat more severe and dynamic facial folds and wrinkles including the corners of the mouth and nasolabial folds. (A dynamic fold or wrinkle is an area on the face where a lot of movement occurs.)

RHA Level 4 

RHA 4 is the first and only FDA-approved HA filler that addresses dynamic deep folds and wrinkles. RHA 4 has the ability to correct severe dynamic facial wrinkles and folds, particularly hard-to-treat nasolabial folds and the lower face.
