Rejuran HB: The Gentle Skin Booster That Does More Than Just Hydrate
Introduction
Salmon sperm facial is a viral treatment currently. You probably saw it on social media, got intrigued and stumbled upon our blog. So what is this Salmon Sperm?
Well, its scientific name is called polynucleotides and one of the brands that contain polynucleotides is Rejuran.
Rejuran itself have 4 types – Rejuran Healer ( black box) , Rejuran I ( white box) , Rejuran scar ( blue box) and Rejuran HB ( red box)
What Is Rejuran HB?
Rejuran HB is part of the Rejuran family, a range of injectable skin boosters made with polynucleotides (PN) from salmon DNA.
Rejuran HB is a type of skin booster injection from PharmaResearch Products, and it’s part of the Rejuran family. H stands for ‘hydration’ and B stands for Brightening.
So compared to classic Rejuran, it’s designed to focus more on moisture + glow.
What’s inside Rejuran HB?
It combines two main components:
- Polynucleotides (PN)
- Hyaluronic Acid (HA)
The functions of Polynucleotides are as such:
1. Tissue Repair & Cell Regeneration
PN are DNA fragments (commonly derived from salmon) that are highly biocompatible with human skin. Once injected, they act as biological signals that:
- Stimulate fibroblasts (cells responsible for collagen production)
- Promote cell turnover and repair
- Help restore damaged skin structure
2. Collagen Stimulation
PN activates fibroblasts to produce:
- Collagen
- Elastin
This gradually improves:
- Skin firmness
- Elasticity
- Fine lines and wrinkles
3. Anti-Inflammatory Effect
PN has been shown to:
- Reduce inflammation
- Support wound healing
4. Improved Skin Environment
PN helps improve the extracellular matrix (ECM)—the “scaffolding” of the skin:
- Enhances skin strength and resilience
- Improves overall skin quality and texture
Hyaluronic acid is no stranger in the aesthetic and skincare world. It has been well known to be a humectant and is able to draw in water into the skin. It also improves the skin barrier by reducing TEWL ( transepidermal water loss) and makes the skin feel smoother.
How Is Rejuran HB Different from Other Rejuran Types?
The Rejuran range consists of different formulations designed to target specific skin concerns, although all of them work using polynucleotides (PN) to repair and rejuvenate the skin at a cellular level.
Rejuran Healer is the original and most well-known version. It focuses on overall skin regeneration, improving skin texture, elasticity, fine lines, and acne scars. It is typically used across the whole face for patients who want general anti-aging and skin healing benefits.
Rejuran I (Eye) is specially formulated for the delicate under-eye area. It has a lower viscosity, making it suitable for thin skin, and helps improve fine lines, dark circles, and skin laxity around the eyes without causing excessive swelling.
Rejuran S (Scar) is a more concentrated and thicker formulation designed specifically for acne scars and deeper skin damage. It is injected more focally into scarred areas to promote stronger tissue repair and collagen remodeling.
Rejuran HB (Hydration + Brightening) combines polynucleotides with hyaluronic acid, making it ideal for patients seeking improved skin hydration, radiance, and a healthy glow. Compared to Rejuran Healer, it is lighter and more focused on enhancing skin moisture and brightness rather than intensive repair.
In summary, while all Rejuran types work on skin healing, Healer is for overall rejuvenation, I targets the eye area, S is for acne scars, and HB is best for hydration and glow.
What Are the Benefits of Rejuran HB?
Rejuran HB is a next-generation skin booster that combines polynucleotides (PN) with hyaluronic acid (HA), offering both skin repair and deep hydration in a single treatment.
One of the key benefits of Rejuran HB is its ability to improve overall skin quality from within. The polynucleotides work to repair damaged skin, stimulate collagen production, and reduce inflammation, making the skin healthier, stronger, and more resilient over time. At the same time, hyaluronic acid delivers intense hydration, helping the skin appear plumper, smoother, and more radiant.
This dual action makes Rejuran HB especially effective for patients with dull, dry, or tired-looking skin, as it restores moisture while enhancing natural glow. Many patients notice improvements in skin texture, fine lines, and elasticity, resulting in a softer and more youthful appearance.
Another advantage of Rejuran HB is that it provides natural-looking results with minimal downtime. Compared to more intensive skin repair treatments, it is lighter and more comfortable, making it suitable even for first-time patients or those seeking maintenance treatments.
Overall, Rejuran HB is ideal for individuals looking to achieve hydrated, glowing, and healthier skin, rather than dramatic volumizing effects making it a popular choice for those pursuing a natural “glass skin” look.
Who Is Rejuran HB Best For?
-
- People with dry, dehydrated, or dull skin who want both repair and hydration
- Those with sensitive skin who find other treatments too irritating
- First-timers who are nervous about injection discomfort
- Anyone looking for a gentler entry point into the Rejuran family
- People who want to improve overall skin quality without targeting a specific scar or eye area concern
