An enhance version of the Watershine HA Booster, also better known as 水光针/ 물광 주사, is the hottest trend in Korea to get glowing skin again. Hyaluronic Acid (HA) is essential in our body to bind, absorb and retain moisture. As we age, our bodies gradually lose HA and collagen, which is why our skin loses the smooth baby skin effect over time. An additional booster made from human stem cells provides additional anti-ageing effects.
