The under-eye area is one of the most delicate parts of the face—thin skin, fine lines, shadows, and dehydration all contribute to a tired look. Two popular boosters used in Korea for under-eye rejuvenation are Rejuran I and Skinvive.
Both improve the under-eye area, but they work very differently.

Here’s a clear comparison to help you choose the right option based on your dark circles, skin thickness, hydration level, and overall goals.

What Is Rejuran I?

Rejuran I is a lightweight PN-based regenerative booster designed specifically for thin and sensitive skin, especially under the eyes.

What It Does

• Strengthens thin under-eye skin
• Improves elasticity and firmness
• Reduces fine lines and crepey texture
• Makes skin more resilient over time

Best For

• Thin, fragile under-eye skin
• Early wrinkles or crepey texture
• Dark circles caused by skin thinning
• People who don’t want volume or puffiness

Result Style

• Natural, subtle tightening
• Gradual brightening
• A smoother, firmer under-eye area

What Is Skinvive?

Skinvive is a hyaluronic acid micro-booster designed to deliver hydration and dewy smoothness just under the skin’s surface.

What It Does

• Hydrates under-eye skin
• Softens fine lines
• Provides light plumping
• Improves glow and texture

Best For

• Dry or dehydrated under-eyes
• Mild hollows or creases
• Tired, dull under-eye appearance
• Anyone wanting a quick “fresh” look

Result Style

• Soft, hydrated, brighter under-eyes
• Subtle plumping that reduces dryness and creases

Which Is Better for Dark Circles?

Choose Rejuran I if your dark circles come from:

• Thin skin
• Fine lines
• Crepey texture
• Skin weakness or early aging

Rejuran I strengthens the foundation of the skin and reduces the transparency that makes veins more visible.

Choose Skinvive if your dark circles come from:

• Dryness
• Surface texture issues
• Mild hollowing
• Lack of glow

Skinvive makes the under-eye look smoother, brighter, and better hydrated.

Which Looks More Natural?

Rejuran I → Most natural for long-term improvement; no volume added.
Skinvive → Natural when done lightly; adds slight plumping for a refreshed look.

Can You Combine Them?

Yes — and this is very common in Korean dermatology.

The Ideal Combination

• Rejuran I to strengthen thin skin and improve elasticity
• Skinvive for hydration and glow once the skin barrier is stronger

This creates:

• A smoother surface
• Brighter tone
• Less creasing
• More resilient under-eye skin

Final Verdict

Choose Rejuran I if you want:

• Stronger under-eye skin
• Less crepiness
• Better elasticity and long-term improvement
• Zero risk of puffiness

Choose Skinvive if you want:

• A hydrated, fresh under-eye look
• Immediate smoothness and glow
• Mild plumping without heavy filler

Choose Both if you want:

• Under-eye skin that is firm + hydrated + bright
• A natural but noticeable rejuvenation effect
