High Inj. – injection solution for skin rejuvenation based on unstabilized hyaluronic acid (HA). High Inj. contains high quality HA from a Japanese manufacturer (Shiseido). HA injections restore the skin’s moisture level, promoting deep and long-lasting hydration while smoothing superficial wrinkles. High Inj. also evens out skin tone and reduces scars, age spots and post-acne blemishes. A more pronounced brightening effect can be achieved with the joint administration of High Inj. with vitamin C.
