Water Glow Injection (Mulgwang) explained

Mulgwang means "water glow" in Korean. It is a skin booster treatment that injects non-crosslinked or lightly crosslinked hyaluronic acid into the upper skin. It improves hydration and fine texture rather than adding volume.

How Water Glow Injection (Mulgwang) works

Hyaluronic acid holds water in the dermis. The doctor uses a multi-needle injector or a fine needle to place many small drops across the face. Some clinics add vitamins, PN or a small amount of toxin to the mix. The skin looks plumper and more reflective as the injections settle.
