Rejuran HB is the hydration-focused member of the Rejuran family, and it is one of the treatments international patients ask for when the goal is dewy, well-hydrated skin rather than a change in shape. It pairs Rejuran’s repair with an added boost of moisture.
This guide explains what Rejuran HB is, how it differs from the original, and who it suits. It is written for international patients, and our English-speaking coordinators can help you plan before you travel.
What Rejuran HB Is
Rejuran HB (the “Hydro Booster”) combines polynucleotides, the salmon-derived repair molecules at the heart of every Rejuran, with hyaluronic acid, the skin’s natural moisture-binder. The polynucleotides support repair and skin resilience while the hyaluronic acid draws in and holds water, so the treatment addresses both the quality and the hydration of the skin in one.
How It Works
Delivered through fine micro-injections, Rejuran HB works on two fronts. The polynucleotides encourage the skin to repair and strengthen its barrier over the following weeks, while the hyaluronic acid provides more immediate deep skin hydration and a smoother, plumper surface. The result many patients notice is a healthier, more luminous look (often described as glow) alongside better resilience.
What Rejuran HB Helps With
Rejuran HB suits dry, dull, dehydrated skin, early fine lines, and a compromised or tired-looking barrier. It is a good fit when the main concern is a lack of moisture and glow rather than volume or lifting. As a deep skin hydration treatment, it is popular before events and for skin that feels depleted.
Rejuran HB and Rejuran Healer
The original Rejuran, sometimes called Healer, focuses on repair and skin quality; Rejuran HB adds hyaluronic acid for a stronger hydration and glow effect. Which suits you depends on your skin (repair-led or hydration-led) and the two are part of the same family. Our guide to Rejuran and the skin boosters overview explain the range.
What a Session Is Like, and What to Expect
A session involves a series of small injections after a numbing cream and is usually quick. Small bumps or mild redness at the injection points are normal afterwards and generally settle within a day or two. Rejuran HB is typically a short course, with results developing gradually and best held with maintenance every several months. Like all boosters, the effect is not permanent.
