For those whose face looks managed but whose hands show their age.
When fat on the back of the hand thins, the tendons and veins beneath stand out and the hand reads as older. Hyaluronic acid spread thinly across the whole back of the hand covers those lines and softens the surface. Because the hand moves constantly and is thin-skinned, an even spread matters more than volume, and it is a place where the touch of the practitioner shows.
One session lasts around twelve months. The hand grips and opens all day long, so how fast it absorbs varies considerably between people. Those who use their hands heavily may see it fade sooner, and since it is spread thinly in a shallow layer, the volume is small to begin with.
