Search for “skin booster” and you’ll run into a wall of names that all sound similar: Juvelook, Vitaran, Rejuran, Gouri. Each one is described as an injectable that improves skin quality, but once you look closer, they sit in different ingredient groups and suit different skin concerns. This article breaks down what each name actually is, which ones Obliv Young Clinic offers, and how Gouri connects to Belluxi — a link most people searching for it don’t know about.
Quick summary
- Juvelook and Vitaran are real Obliv Young services, from two different ingredient groups (PDLLA+HA and PN)
- Rejuran is a name the market talks about often, but it is not currently offered at Obliv Young
- Gouri and Belluxi are made by the same manufacturer using the same active ingredient at the same concentration — Belluxi is what Obliv Young actually offers
- No single option is “best” for everyone — it depends on your specific skin concern
- Result timelines and pricing depend on an individual doctor’s assessment, not a fixed number
What sets a skin booster apart from filler
A skin booster works by supporting the skin’s own recovery process from within, rather than adding volume to a specific area the way filler does. Results tend to build gradually rather than appear instantly, and most skin boosters are planned as a short course rather than a single session.
Comparing the four names people search for
| Name | Main ingredient group | What it’s known for | Offered at Obliv Young? |
|---|---|---|---|
| Juvelook | PDLLA (Poly-D, L-Lactic Acid) + Hyaluronic Acid | Instant hydration from HA plus ongoing collagen stimulation from PDLLA | Yes |
| Vitaran | Polynucleotide (PN) | Supports the skin’s natural recovery process, targets dull or dehydrated skin and uneven texture | Yes |
| Rejuran | Often grouped as a regenerative injectable (PN-adjacent) | Commonly described in the market as repairing accumulated skin damage | No — mentioned here for context only |
| Gouri | Polycaprolactone (PCL), 210 mg/ml, made by DexLevo | A name many people recognize from the Korean market | No exact match — but Belluxi, made by the same manufacturer with the same ingredient, is |
Juvelook: what it actually does
Juvelook works in two phases. Hyaluronic acid hydrates the skin from the first session, giving an immediate, more radiant look. Over the following weeks, PDLLA stimulates fibroblast cells to keep producing new collagen and elastin. Results tend to build up gradually within 1–2 months and can last up to around 12 months, though this varies by individual. It tends to suit people dealing with dull, dehydrated skin or early fine lines who want both an immediate glow and a longer-term firming effect. Read more on the Juvelook service page.
Vitaran: how it’s different from Juvelook
Where Juvelook leans on an immediate hydration boost, Vitaran works more slowly from within. It belongs to the Polynucleotide (PN) group, which supports the skin’s own natural recovery process rather than adding hydration on top. Once injected, PN encourages fibroblast activity to help repair the skin. It tends to suit people dealing with skin that’s uneven in texture, enlarged pores, acne scarring, or dulled by long-term external damage — more of a repair-focused approach than an instant-glow one. It’s usually planned as a short course rather than a single visit, with the exact number of sessions decided after an individual skin assessment. Read more on the Vitaran service page.
Gouri — and why it’s actually about Belluxi
This is the part worth clearing up, because a lot of people search “Gouri” without realizing it connects to something Obliv Young already offers. Gouri is a Polycaprolactone (PCL) injectable at 210 mg/ml, manufactured by DexLevo in Korea. Belluxi, which Obliv Young does offer, is manufactured by the same company — DexLevo — using the same active ingredient at the same 210 mg concentration. In plain terms: same manufacturer, same ingredient, same concentration, different market name. To be precise, there’s no single source confirming the two are the exact same formulation down to the letter — what’s confirmed is the shared manufacturer and matching ingredient specs. If you were searching for Gouri specifically, Belluxi is the closest real option available in Thailand. Read more about Belluxi on its service page.
What about Rejuran?
Rejuran is a familiar name, often grouped with regenerative, PN-adjacent injectables and commonly described in the market as targeting accumulated skin damage. It is not currently part of Obliv Young’s service list. This article mentions it only to give a full picture of the market — not as something you can book here. If the PN mechanism is what you’re after, Vitaran is the closest service Obliv Young actually offers.

So which one should you choose?
- Dull, dehydrated skin, want a quick visible improvement — Juvelook, thanks to its HA component
- Skin that’s been damaged over time, slow to recover, uneven texture — Vitaran, thanks to the PN mechanism
- Interested in the PCL, long-term-structure category — Belluxi is the closest real match to Gouri available here
- Not sure what your skin actually needs — don’t guess. A doctor’s assessment is the safer starting point
Safety basics worth knowing
Skin boosters are generally considered a low-downtime treatment, though some people experience mild redness or swelling after injection. Suitability and side effects vary by individual skin condition and health history. If you’re pregnant, breastfeeding, have a blood clotting condition, have a history of allergic reactions, or are on certain medications, tell your doctor before deciding on any treatment. No treatment should start without a proper assessment first.
Frequently asked questions
Does Obliv Young offer Rejuran or Gouri?
Not under those names. Obliv Young’s main skin boosters are Juvelook and Vitaran. Rejuran and Gouri are covered in this article for market context only. If you’re interested in a similar mechanism, Vitaran (PN) or Belluxi (PCL, the closest match to Gouri) are the real options available.
Are Juvelook and Vitaran the same kind of treatment?
No. Juvelook is a PDLLA plus HA combination, while Vitaran belongs to the Polynucleotide (PN) group. The mechanisms and strengths differ, so it’s worth letting a doctor assess which fits your specific concern better.
Does a skin booster injection hurt?
Sensation varies by person. Most people describe mild tightness or brief discomfort, with some redness or swelling that usually settles within a few days, depending on the injection site and individual skin.
How many sessions before I see results?
A commonly seen approach in the market is a short course spaced a few weeks apart, but the right number for you depends on your skin condition and goals. Your doctor will plan this individually.
Who should talk to a doctor before trying a skin booster?
Anyone who is pregnant, breastfeeding, has an underlying health condition, has a history of allergic reactions, or is taking certain medications should disclose this to a doctor before deciding.
How much does a skin booster cost?
Pricing depends on the specific treatment, number of sessions, and the plan your doctor recommends for your skin. It’s best to consult the clinic directly for an accurate quote based on your own concerns.
