To start with the conclusion, although both treatments fall into the same "hydration, texture, and glow" category, there is a clear difference in their injection depth. Rejuran HB is injected into the upper-to-mid and deep levels of the dermis* to stimulate cell regeneration and provide instant hydration. On the other hand, Belotero Revive is injected deeply into the subdermal layer* to deliver moisture, refine skin texture, and create a subtle volume. Repeated sessions on the same area yield different results — in particular, Revive works to slightly increase facial volume.

Dermis*: This is the skin layer right beneath the epidermis, rich in collagen and elastin. Most of your skin's thickness and elasticity depend on the condition of this layer.

Subdermal Layer*: This is the layer beneath the dermis containing fat and connective tissue. It defines the facial contours and volume. When a viscoelastic substance is placed here, it brings about a subtle increase in volume along with its moisturizing benefits.

The Biggest Divider Between the Two Treatments — Injection Depth

Rejuran HB is distributed from the upper-to-mid dermis down to the deep dermis. The PN (Polynucleotide)* component settles in the deep dermis to stimulate cell regeneration, while the combined Hyaluronic Acid (HA) and lidocaine work in the upper-to-mid dermis to provide hydration, glow, and pain relief. The key here is that the injection remains within the dermis and rarely reaches the subdermal layer.

PN*(Polynucleotide): A DNA fragment extracted from salmon testes. It penetrates skin cells to directly stimulate the regeneration of damaged cells and collagen synthesis. This is the core active ingredient in the Rejuran line.

Belotero Revive takes a different approach. The official guideline from Merz Aesthetics suggests injection into the mid-to-deep dermis, but the standard clinical technique in Korea is to inject down to the immediate subdermal layer using a thin 33G needle. It is formulated with lightly cross-linked HA and glycerol to lock in moisture for longer. Since glycerol plays a moisture-lock role, it provides longer-lasting hydration than simple HA skin boosters.

Even though they are in the same category (skin boosters for hydration and glow), the fact that one is an intradermal treatment and the other is a subdermal treatment is what defines their different results.

The Effects of Revive's Subdermal Injection on the Face

This is the most frequently overlooked detail when comparing these two procedures. Merz's official IFU (Instructions for Use) specifies a "subtle volume-filling effect" for Revive and warns of "potential unwanted volume changes in unintended areas."

The science behind it is simple. Unlike the dermis proper, the subdermal layer has more empty space, and once cross-linked HA settles there, it naturally takes up volume. A single session might show a subtle difference, but after a cumulative series of three sessions, the treated area can appear slightly plumper. Areas like the outer cheekbones, the center of the cheeks, and the jawline are highly susceptible to this effect. Even the consensus guidelines on PDLLA + HA regarding the depth-specific actions of HA fillers state that injecting HA into the subdermal layer brings about subtle volume-boosting effects in addition to hydration.

This is not a drawback, but rather a matter of choice.

If you are someone who easily feels conscious about your face looking bloated or puffy, you should carefully consider cumulative subdermal injections of Revive in the cheekbone and cheek areas. Your very first step should be to clearly decide in your consultation whether "you only want hydration, or if you are okay with a bit of volume as well."

Rejuran HB's True Value — Healing and Pain Relief

Rejuran HB differs from the standard Rejuran (Healer) in two key ways. First, the addition of Hyaluronic Acid delivers an immediate boost in hydration and glow. Second, it contains lidocaine, an anesthetic, which reduces treatment pain by about 50%. Standard Rejuran contains PN alone, making the injection process quite painful.

According to a prospective observational study on Polynucleotide injections for fine wrinkles around the eyes, PN stimulates fibroblasts to synthesize collagen while simultaneously triggering anti-inflammatory and regenerative signals. Rejuran HB builds on this with the immediate hydrating effects of HA.

Since Rejuran HB is a treatment that remains within the dermis, there is almost no change in facial volume. Although tiny bumps (embossing) may appear for 1 to 2 days immediately after the treatment, they soon subside. The core benefit of this treatment is "hydration and glow only, keeping your face its natural size."

However, there is one detail to keep in mind. Some clinical opinions suggest that while Rejuran HB reduces pain, its regenerative effect might be slightly milder than the original Rejuran Healer. This is because, within the same volume of injection, the PN concentration is shared with HA and lidocaine. If intense skin healing is your top priority, choose the standard Rejuran; if pain relief and immediate hydration are your priorities, HB is the way to go.

Which Treatment is Right for You?

Your choice depends entirely on your primary skin concern. Here is a quick summary:

• Immediate hydration + healthy glow + maintaining natural face size → Rejuran HB

• Long-lasting moisture + refined texture/tone + subtle volume is okay → Belotero Revive

• Intensive regeneration + soothing care → Standard Rejuran (Healer)

• Need defined, noticeable volume → PDLLA subdermal injection (like Juvelook Volume — a different category)

• Concerned about a puffy-looking face → Exercise caution with repeated Revive treatments

Even within the same category, results vary depending on injection depth and active ingredients. Our comparison of [Rejuran HB vs. Juvelook Subdermal Injection] touched on similar depth discussions, but while that article compared skin boosters with long-term collagen stimulators (PDLLA), this article compares hydration-focused skin boosters. Even when the keyword is "subdermal injection," the timeline of the expected results can be very different.

We recommend summarizing your main concerns in one or two lines before your consultation. If you are clear on whether "a lack of moisture is your main concern, skin texture is your top priority, or if you welcome a puffier, more volumized look or not," your provider can easily select the perfect treatment plan for you.

Frequently Asked Questions

Q. Will my face really look bigger after 3 sessions of Revive?

Rather than "bigger," "subtly plumper" is a more accurate expression. Merz's official guide explicitly notes a subtle volume-filling effect. If your treated areas are concentrated on the cheekbones or the center of the cheeks, you might feel those areas have become slightly filled out. If you wish to avoid any extra volume, let your provider know beforehand so they can adjust the injection depth to a shallower level or reduce the dosage.

Q. Can I receive Rejuran HB and Revive together?

Yes, if they are injected into different areas. For example, you can target the cheekbones with Rejuran HB (to avoid volume changes) while placing Revive on the center of the cheeks where the skin texture feels rough. We do not recommend receiving both treatments on the exact same area on the same day. Doing so makes it difficult to evaluate the efficacy and increases the risk of side effects.

Q. If their longevity is similar, how do they compare in price?

While the cost per session varies depending on the treatment area and dosage, Belotero Revive is generally slightly more expensive per session than Rejuran HB. Since both typically require a standard series of three sessions, the difference in total cost is not very significant. You should make your choice based purely on your primary skin goals.
