Skin boosters and Rejuran treatments in Korea are popular injectable dermatology procedures designed to improve skin hydration, texture, and overall skin quality. Both treatments are commonly offered at Korean dermatology clinics and are widely used to achieve brighter, smoother, and healthier-looking skin.
Although they are often grouped together, skin boosters and Rejuran work differently. Skin boosters mainly focus on deep hydration and glow, while Rejuran focuses on skin regeneration and repair at the cellular level.
Why Compare Skin Boosters and Rejuran?
- Both treatments improve skin quality and texture
- Popular injectable treatments at dermatology clinics in Korea
- Non-surgical procedures with minimal downtime
- Used for achieving hydrated and radiant skin
- Often included in customized skin rejuvenation programs
What Are Skin Boosters?
Skin boosters are injectable treatments that deliver hydrating substances directly into the skin. Most skin boosters contain hyaluronic acid (HA), a molecule that attracts and retains water, helping the skin appear smoother, plumper, and more radiant.
Skin boosters work by injecting small microdroplets into the skin, which improves hydration and surface texture.
Skin boosters are commonly used to treat:
- Dry or dehydrated skin
- Dull complexion
- Fine superficial lines
- Uneven skin texture
- Enlarged pores
Results from skin boosters often appear relatively quickly because the treatment primarily focuses on hydration and glow.
What Is Rejuran Treatment?
Rejuran is a regenerative skin treatment developed in Korea that uses polynucleotides (PN) derived from salmon DNA. These molecules stimulate skin repair and help regenerate damaged skin cells.
Unlike typical skin boosters, Rejuran focuses on improving the skin’s structure and healing capacity rather than simply hydrating it.
Rejuran treatments are commonly used to improve:
- Skin regeneration and repair
- Fine lines and wrinkles
- Acne scars and damaged skin
- Skin elasticity and texture
- Sensitive or irritated skin
Results usually appear gradually as the skin undergoes regeneration and collagen stimulation.

Key Differences Between Skin Boosters and Rejuran
Skin boosters mainly focus on deep hydration and immediate skin glow, while Rejuran focuses on skin repair and regeneration.
Skin boosters typically produce faster visible results because they hydrate the skin directly. Rejuran treatments work more gradually by stimulating skin healing and collagen production, which can improve skin quality over time.
Skin boosters are often recommended for patients with dry or dull skin, while Rejuran is commonly recommended for those with damaged, sensitive, or aging skin.
