It is done in three to four sessions at two to four week intervals. It does not finish in one — the skin thickens and fine lines shallow as sessions add up, because it stimulates cells to produce for themselves and the response has to accumulate. After the course, the interval widens for maintenance.

Texture is felt smoothing from around the second session, and the change in thickness appears over one to two months after finishing three or four. It works on the skin repairing itself rather than laying moisture on the surface, so it takes time. HB includes hyaluronic acid, so early hydration comes first.

A water-glow injection fills with hyaluronic acid, so hydration is immediate and it disappears when absorbed. Rejuran uses a regenerative ingredient from salmon to let the skin recover itself, so change is slower but lasts. If you need glow now choose Aqua Injection; to change the skin’s condition itself, Rejuran.
