Description
Key aspects
- Ingredient: The key active ingredient is polynucleotides (PN), which are DNA fragments from salmon.
- Mechanism: PN stimulates the skin’s natural healing processes by triggering fibroblasts to produce collagen and elastin, improving tissue repair, and increasing blood flow.
- Benefits:
-
- Improved skin texture and elasticity
- Reduced appearance of fine lines, wrinkles, and pores
- Increased skin hydration and firmness
- Reduced scarring, including acne scars
- Improved dark circles around the eyes (especially with specialized formulas)
- Anti-inflammatory effects
- Application: Rejuran is delivered via multiple tiny injections into the skin, similar to other skin boosters. There are different formulations, some of which are mixed with hyaluronic acid.
- Treatment course: A common protocol is 3 to 6 treatments spaced about four weeks apart, followed by maintenance treatments every 6 months to a year.
- Results: Effects are gradual, appearing over time as the skin regenerates.
- Precautions: Not recommended for pregnant or breastfeeding individuals, those with high blood pressure, or people with certain medical conditions. It’s important to inform your doctor about recent cosmetic procedures.
Differentiate from other treatments
- Not a filler: Unlike traditional fillers that add volume, Rejuran focuses on skin regeneration.
- Different from biostimulators: While biostimulatory fillers also promote collagen, Rejuran’s polynucleotides are specifically the “building blocks” for new DNA, rather than just growth factors.
