Hyaluronic acid fillers were first introduced in Korea 20 years ago, when Restylane was approved in 1999. Today, the number of filler brands approved by the KFDA is over 150, and 20~30 brands are actively distributed in the market.
Among the many types of fillers, the most widely used is the Hyaluronic acid filler for its proven safety. Hyaluronic acid can be found naturally in eyes, bones and cartilage, but over 50% of HA in the body is found in the skin. This is why it has minimal side effects when injected in the skin, and if there is, it can easily be reserved using hyaluronidase to dissolve the hyaluronic acid.

In the early stages of its administration, fillers were primarily used for wrinkles around the eyes, between the eyebrows, and for nasolabial folds and marionette lines. In Korea, it was most widely used to get rid of nasolabial folds and marionette lines.

The next trend was using fillers to give volume to specific parts of the face. Areas like the cheek, lips and forehead, when given volume with fillers can give more defined facial features and help you look younger.

Then came the technique of injecting hyaluronic acid across the whole face, hence the hydro injection. As one gets older, the natural volume of HA in the body decreases, especially as one gets into his or her 40s. This causes your skin’s moisture retaining level to drop, which is why your face gets drier with age. On the face specifically, the drop in HA levels is more serious in the cheek area (called the U-zone) than the area (called the T-zone) where there are more sebaceous glands, the glands that make your skin oily. Hydro injection involves injecting Hyaluronic acid in minute amounts across a wide area of your skin, mainly this U-zone, to moisturize your skin and reduce light wrinkles.
