Non-Surgical · Comparison
A repair signal or added hydration: two different jobs
Apgujeong, Gangnam, Seoul | Board-certified plastic surgeon, Dr. Jonghwan Choi
Product chosen after examination by one plastic surgeon · KHIDI-registered
The difference
The short answer
Both are injected into the skin, and they do different jobs. Rejuran is a polynucleotide booster, placed as a repair signal that the skin responds to over the following weeks. A water glow injection, in the usual sense of the phrase, delivers hyaluronic acid for hydration that is felt sooner and fades gradually. On Rewind's rate sheet, the hydration vials are SkinVive and ByRyzn.
Skin booster names the whole category and Rejuran is one product within it, so this page compares Rejuran with the hydrating part of the menu.
The phrase water glow travels loosely. It is used for hydrating injections in general, and on Rewind's own menu it also appears inside the whitening package as a water-glow PDRN item. The first task at consultation is therefore to pin down which product a quote actually names, since two injections sold under similar words can contain quite different materials.
Hyaluronic acid is the skin's main water-holding molecule. A 2012 review of its role in skin ageing calls it the key molecule in skin moisture because of its unique capacity to retain water. Polynucleotide acts on a different axis, as a signal for repair, and that difference is what decides which of the two a doctor reaches for first.
Four differences
The menu treats these as separate tools. Each answers its own complaint, on its own timescale.
Mechanism
Both products are placed in the dermis. What happens after that is where they separate.
A hydrating booster adds a water-holding molecule to the dermis, so the skin feels plumper and reflects more light while it lasts. The effect fades as the body breaks the material down.
In a 2015 case series in which five Korean women received polynucleotide injections, the authors described the material as improving tissue regeneration beyond filling space. Reported changes included pores and skin thickness in the younger patients, and tone and wrinkles in the older ones.
A 2015 paper on intradermal hyaluronic acid for fine lines describes crepey skin as a dermal sign of age-related volume loss. Very superficial lines can therefore be approached with either material, and the choice depends on what else the skin needs.
Rewind's booster guidance gives a band of one to three months up to more than a year, depending on the product and the condition of the skin. Maintenance is planned for both.

Sequence
There is no fixed rule, and Rewind does not publish one. The order follows the main complaint and, for visitors to Seoul, the length of the stay.
Skin that feels tight and dry through the day often starts with hydration, the quicker change a patient can feel. Rejuran can follow if thinness or crepe remains once the skin is holding water again.
If the problem is fragile, fine-lined skin, particularly below the eye where Rejuran i is used, the polynucleotide line may come first and hydration later, or not at all.
Running two booster classes together makes it impossible to tell which one worked or which one caused a reaction. Outside the sets defined on the rate sheet, one product is completed and reviewed before the next is added.

Either appointment begins with the consultation, where the product is named and the zone agreed. If you arrive with a product name from an advertisement, bring it along; the doctor will tell you whether it matches the complaint. Both are injected in the clinic's own treatment rooms on the fourth and fifth floors of the Richro Building in Apgujeong, Gangnam, open by appointment on Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and Saturday from 10:00 to 16:00.
After the injection, both can leave small marks that settle. Rejuran's own sheet adds two to three days away from pressure, heat and alcohol, which matters if the two are planned for a single trip.
Pricing
The five items below sit on the same rate sheet. The two hydration vials are sold as sets that include a light botulinum toxin dose across the butterfly zone of the cheeks.
VAT is added to every listed rate at payment, and anaesthesia, where used, is already included. The water-glow PDRN item appears only inside a package, which is quoted at consultation.
Fit
Aftercare
The general booster instructions apply to both products. Rejuran has its own sheet on top of them.
Faint redness and stinging can follow either injection and mostly settle within a few days. Rejuran carries the possibility of an ingredient allergy. Infection and vascular occlusion are rare with skin injections and serious; blanching, dusky skin or rising pain need a call to the clinic the same day.
At Rewind, one board-certified plastic surgeon carries every case — from the first consultation to the final follow-up. Because a face is a story, and a story deserves a single author.

Scientific evidence
The first paper is a five-patient case series of polynucleotide injection; the second reviews hyaluronic acid as the water-holding molecule of the skin; the third discusses intradermal hyaluronic acid for fine lines. None was carried out at Rewind, and none compares Rejuran with a specific hydration vial.
