Korean Skin Boosters Compared: Rejuran, Juvelook, Hylo-Wave, GOURI, Re2O and Cellredm (2026)

A skin booster is an injectable placed in or just under the skin to improve skin quality: hydration, texture, firmness, tone, and in some cases mild volume. It is different from a filler, which is mainly used to shape and add volume in a specific spot.

For choosing, I find it helpful to sort boosters into three rough groups:

• Repair and calming: boosters such as Rejuran (PN, polynucleotide) that support the skin’s recovery. Well suited to thin, tired, sensitive skin.
• Collagen-stimulating: boosters such as Juvelook (PDLLA) and GOURI (liquid PCL) that prompt your skin to build collagen over weeks. Better for texture, pores, scars, mild hollowness and firmness.
• Newer structure-focused boosters: Re2O is an ECM-type booster, based on the extracellular matrix that supports skin cells. I explain why this matters in my video on why some skin boosters don’t seem to work.

Hylo-Wave and Cellredm sit across these groups, which is why I describe them by what I use them for below.

Booster	What I mainly use it for	How results come
Rejuran (Healer, HB, Eye)	Thin, sensitive or tired skin; fine uneven texture; crepey under-eyes (Eye)	Gradual over weeks; best as a series
Juvelook Skin / Juvelook Volume	Pores, acne scars, uneven texture (Skin); mild hollows (Volume)	Collagen builds over about 1 to 3 months
Hylo-Wave	Skin quality plus soft volume, including the tear trough and areas that look hollow	Some change early, more over the following weeks
GOURI	Overall firmness and mild sagging across the face, without a filled look	Gradual collagen-type change over weeks
Re2O	Texture and skin density, often in thin or aging skin	Gradual
Cellredm	Whole-face texture, pores and tone; often paired with Juvelook Skin or Sylfirm X	Gradual

The “how results come” column is a general pattern, not a promise. Your skin thickness, age and sun damage change the timeline.

“My skin is thin, sensitive and easily red”

Start with Rejuran. It is the booster I reach for when skin needs to recover before anything stronger. See our Rejuran Healer page for details.

“My pores are large and I have acne scars”

Juvelook Skin is usually a better fit, often combined with Sylfirm X or with Cellredm for the whole face. Read more on the Juvelook page.

“My face looks hollow and tired, especially under the eyes or below the cheekbones”

Hylo-Wave, Juvelook Volume or GOURI. For a “peanut-shaped” face where the cheeks look sunken under the cheekbones, I explain the approach in this video on hollow cheeks.

“My skin feels loose, but I’m not ready for strong lifting”

GOURI is one option, sometimes called “liquid lifting”. It is worth knowing its limits, which I cover in my honest answer on liquid lifting.

“I want everything”

Most people have one main concern and one or two smaller ones. I treat the main one first. Stacking four boosters in one visit is more expensive and rarely necessary.

• Clear sagging along the jawline or jowls. Boosters improve skin quality; they do not replace lifting. Energy-based lifting such as Ultherapy PRIME, Onda or XERF may suit you better.
• Pigmentation such as melasma or sun spots. That is usually a laser and skin-care question first.
• Active acne or infection in the area. We calm that down before injecting.
• Pregnancy or breastfeeding. We wait.
• A known allergy to an ingredient, such as fish products for Rejuran. Tell me in the consultation.

I would rather tell you to skip a booster than sell you one that won’t do what you hope.

1. WhatsApp consultation before you travel: send makeup-free photos in daylight and your main concern. You get my opinion and an estimate.
2. Arrival at 121 Dosan-daero near Sinsa Station. Consultation is on the 3rd floor.
3. EVE MUSE 3D skin analysis to map texture, pores, pigment and redness.
4. Consultation with me to choose the booster, dose and injection areas.
5. Numbing cream, about 30 to 40 minutes.
6. Injection in a private room, usually 15 to 30 minutes depending on the booster and area. Multiple small injections are common for boosters; some are placed with a cannula.
7. Aftercare instructions and follow-up after you leave.

What changes the price: the dose your skin needs, the area (full face, under-eyes, neck), whether you need one booster or a combination, and the number of sessions. A cheap per-cc price means little if the dose is low.

Patients usually report that skin looks less tired and makeup sits better within a few weeks, with collagen-type boosters continuing to change over one to three months. Results vary, and boosters are gradual by nature.

• Day 0: small bumps at injection points (most visible with Rejuran and Juvelook), redness, possible bruising.
• Days 1 to 3: bumps settle for most people. Light makeup is usually fine from the next day.
• Up to about a week: bruises fade. Under-eye treatments can swell a little more.
• First week: no alcohol, smoking, sauna or strong massage on the treated area. Sunscreen daily.

Risks include bruising, swelling, infection, and with collagen-stimulating boosters, small lumps if placed or prepared incorrectly. Correct dilution and depth matter, which is one reason the doctor’s experience matters.

• Book your booster on day 1 or 2 of your trip, and allow about 2 hours at the clinic.
• Most people can fly the next day. Pack SPF 50.
• If you also plan lifting or laser, tell us in advance; we plan the order on the same visit.

When comparing clinics, ask to see the sealed box or vial before opening and check the authenticity label or QR code where there is one. Ask how many cc or vials you are getting, and who injects. You can read about my background on Dr. Ha Chang-ik’s profile.
