Rejuran Injections: 4 Benefits + Post-Treatment Precautions to Avoid Side Effects

Rejuran injections, also known as skin boosters, originated in Korea and have become a popular aesthetic treatment. When injected into the skin, they can immediately improve skin condition, repairing damaged cells, enhancing hydration, and boosting elasticity. The term Rejuran literally refers to these Korean skin booster injections, which deliver nutrients and moisturizing ingredients directly into the skin for visible rejuvenation effects. Here’s a detailed breakdown of 4 major benefits of Rejuran and important post-treatment precautions to minimize risk.

1. 4 Key Benefits of Rejuran Injections

1. Anti-Aging and Youthful Skin

• Reduce wrinkles and fine lines, improve sagging: Rejuran stimulates collagen and elastin production, significantly reducing wrinkles and fine lines, tightening the skin, and improving sagging for a youthful appearance.
• Enhance facial contours: Beyond surface improvements, Rejuran can enhance facial structure from deeper layers, creating a more defined, youthful contour and radiant skin.

2. Skin Regeneration and Repair

• Repair damaged skin: Rejuran accelerates healing of sun damage, acne scars, and other skin injuries, promoting collagen production and restoring damaged cells.
• Even skin tone and brighten: By stimulating cell turnover, it improves uneven skin tone, reduces dark circles and spots, and enhances overall radiance.
• Refine pores and improve texture: Collagen stimulation tightens tissue around pores, helping to shrink them and improve skin texture.

3. Scar Improvement

Rejuran promotes fibroblast activity, collagen, and elastin synthesis, and stimulates skin cell regeneration. This helps scars more closely resemble normal skin, improving texture, elasticity, and overall skin structure.

4. Hydration and Moisture Retention

Rejuran provides essential hydration, improving dry skin and enhancing barrier function. Its moisturizing effect makes skin look plump, supple, and resilient, while also offering anti-inflammatory benefits.
