Quick answer: In Rejuran vs Skinvive, the main difference is repair versus hydration. Rejuran uses polynucleotides (PN) to help damaged, thin or sensitive skin heal and regain elasticity. Skinvive uses hyaluronic acid microdroplets to hydrate the skin and improve smoothness and glow. Choose Rejuran for skin repair, and Skinvive for dewy, hydrated, smoother skin.

What is Rejuran?
Rejuran is a Korean skin booster made by PharmaResearch. It contains polynucleotides (PN), DNA fragments from salmon, injected in small amounts across the face. PN supports the skin's natural repair, which can improve elasticity, fine lines, pores, redness and the look of early acne scars. It is popular for thin, tired or sensitive skin and for recovery after lasers.
What is Skinvive?
Skinvive by Allergan Aesthetics is a hyaluronic acid (HA) microdroplet injectable. A very light HA gel with a small amount of lidocaine is placed in tiny amounts across the cheeks. HA holds water, so the skin looks more hydrated, smooth and glowing. In the United States, Skinvive is FDA-approved to improve cheek skin smoothness in adults. Results commonly last about six months.

Which is better for damaged or sensitive skin?
Rejuran is often the better choice when the skin is red, reactive, thin or recovering from acne or lasers. PN supports the healing process and can make the skin feel stronger and calmer. Many people use Rejuran as a regular treatment for skin health.
Which is better for hydration and glow?
Skinvive is often the better choice when your main concern is dryness, dullness or rough texture on the cheeks. The HA draws in water and gives a fresh, dewy look within days to weeks. It is a good option before an event or for people who want a quick glow.
Can you combine Rejuran and Skinvive?
Yes. Some doctors combine both in a plan: Rejuran for repair and elasticity, and Skinvive for hydration and smoothness. They may be done on different days or together, depending on your skin. Both also pair well with laser toning and lifting devices.
What is the downtime?
After Rejuran, small raised bumps appear and usually settle within a day or two. After Skinvive, you may see redness, small bumps, swelling or bruising for a few days. Most people return to normal plans the next day, and makeup is usually fine after 24 hours.
Is it safe?
Both are safe when injected by trained doctors with genuine products. Possible side effects include redness, swelling, bumps and bruising. Rare risks include infection or lumps. Tell your doctor about fish allergies before Rejuran and about lidocaine allergies before Skinvive.
