Hydro-injection·Salmon Injection·Vitamin Injection: Types and Effects of Skin Beauty Injection Procedures

Hydro-injection, Salmon Injection (Rejuran), and Vitamin Injection are representative aesthetic injection procedures performed in dermatology clinics to improve various skin concerns such as skin hydration, elasticity enhancement, and whitening. Each procedure differs in the injected components and expected effects, so it is important to consult with a specialist and choose according to your skin condition and goals.

Hydro-injection: A Solution for Moist and Elastic Skin

Hydro-injection primarily involves directly injecting hyaluronic acid into the dermal layer of the skin to increase internal skin moisture and improve the overall skin environment. Hyaluronic acid has the ability to attract hundreds of times its own weight in water, making it highly effective for skin hydration and also helping to enhance skin elasticity.

  • Key Ingredient: Non-crosslinked Hyaluronic Acid
  • Expected Effects: Improved skin hydration, fine wrinkle reduction, skin texture improvement, enhanced skin elasticity
  • Treatment Cycle: Generally, 3 sessions are recommended at 2-4 week intervals, and for maintenance, a session every 3-6 months can be considered. This may vary depending on individual skin condition and duration of effect.

Temporary redness, swelling, or injection marks may appear after the procedure, but most disappear naturally over time. For those sensitive to pain, the procedure is performed after applying an anesthetic cream.

Salmon Injection (Rejuran): Activating Skin Regeneration Capabilities

Rejuran, commonly known as Salmon Injection, is a procedure that involves injecting polynucleotide (PN) extracted from salmon to improve the internal skin environment and activate its self-regenerative capabilities. PN is known to promote skin cell regeneration and induce collagen production, which can help improve skin elasticity and density.

  • Key Ingredient: Polynucleotide (PN)
  • Expected Effects: Strengthened skin barrier, improved skin elasticity and density, fine wrinkle reduction, oil-water balance regulation, improved skin tone
  • Treatment Cycle: Generally, 3-4 sessions are recommended at 2-3 week intervals, and subsequent periodic treatments can be considered for maintenance.

Rejuran treatment focuses on making the skin healthy from within, so consistent treatments can positively impact overall skin health improvement. After the procedure, temporary embossing or redness may appear but usually improves within a few days.

Vitamin Injection: Skin Whitening and Antioxidant Effects

Vitamin Injection is a procedure that primarily uses high-dose Vitamin C as its main component, either injected directly into the skin or administered intravenously. Vitamin C, through its powerful antioxidant action, can inhibit melanin pigment production and promote collagen synthesis, thereby helping with skin whitening, improvement of hyperpigmentation, and enhancement of skin elasticity.

  • Key Ingredient: Vitamin C (Ascorbic Acid) and various vitamin complexes
  • Expected Effects: Skin whitening, improvement of hyperpigmentation (melasma, blemishes), antioxidant action, skin tone equalization, collagen production promotion
  • Treatment Cycle: Varies depending on skin condition and goals, but generally, treatments are often received consistently at weekly intervals.

Vitamin Injection can contribute not only to skin whitening but also to overall skin health and immune system enhancement. However, when high-dose vitamins are injected, side effects such as gastrointestinal disorders or kidney stones may occur depending on the individual, so it is essential to consult with a medical professional before deciding on the procedure.

Guide to Choosing the Right Injection Procedure for You

Various aesthetic injection procedures such as Hydro-injection, Salmon Injection, and Vitamin Injection each have clear advantages and expected effects. Therefore, it is important to choose the appropriate procedure according to your skin concerns and goals.

  • If you have dry, dull skin and are concerned about fine wrinkles: You can focus on replenishing skin moisture and improving elasticity through Hydro-injection.
  • If your skin barrier is weak, elasticity is reduced, and you desire fundamental skin regeneration: Salmon Injection (Rejuran) can help enhance the skin's regenerative power.
  • If you are concerned about dull skin tone and hyperpigmentation (melasma, blemishes): You can expect whitening effects and antioxidant action through Vitamin Injection.

In some cases, multiple procedures can be combined or performed in conjunction to achieve greater synergistic effects. However, all procedures have individual variations and the possibility of side effects, so it is crucial to consult thoroughly with an experienced dermatologist to establish the most suitable treatment plan for your skin type and health condition.
