Rejuran Skin Booster and HIFU: Addressing Skin Repair and Tissue Lifting
Quick summary: Rejuran Skin Booster (DEP) and HIFU are two treatments that work at different depths of the skin: one focused on supporting skin hydration and radiance, the other on lifting and tightening the underlying tissue. For patients whose concerns involve both skin quality and early structural laxity, a doctor may consider both as part of a structured care plan. A full clinical consultation is required before either treatment.

Two Treatments. Two Different Skin Problems.
As skin changes over time, it’s common to notice more than one concern at once. Skin may appear drier, rougher, or less radiant, while facial contours may become softer or less defined. Although these changes can occur together, they involve different layers of the skin and may require different clinical approaches.
If you’ve been researching skin rejuvenation options in Singapore, you’ve likely come across both Rejuran Skin Booster (DEP) and HIFU. They’re two of the more commonly discussed treatments at aesthetic clinics, and for a specific reason: each addresses a distinct concern differently.
Understanding how they work — and why some patients end up considering both — can help you ask better questions during your consultation.
What Rejuran Skin Booster Addresses
Rejuran Skin Booster (DEP) (a salmon-DNA-derived skin booster) is a Korean-developed cosmetic treatment built around PDRN (Polydeoxyribonucleotide) and amino acids, delivered topically through dermo-electroporation (DEP) — a non-injection method that uses gentle electrical pulses to help the formula penetrate the skin’s surface layers. PDRN is understood to support the skin’s own surface renewal processes and may help with hydration and radiance.
The amino acid component works alongside the PDRN and may help support hydration, which is why this skin booster is commonly considered for skin that has become dull, dehydrated, or fatigued from ageing or external factors.
Rejuran Skin Booster (DEP) is typically considered for:
- Skin dullness, dehydration, or loss of radiance
- Fine surface lines and uneven texture
- Skin that has lost its bounce or become fatigued over time
- Post-procedure skin that could use extra surface support
This DEP-delivered format works at the skin’s surface and outer layers. It doesn’t address tissue laxity or structural sagging, which involves a different, deeper layer of the face entirely.
What HIFU Addresses
HIFU (High-Intensity Focused Ultrasound) is a medical technology that delivers focused ultrasound energy deep beneath the skin’s surface, reaching deeper tissue layers beyond what topical treatments can access. At these depths, it’s designed to target the deeper SMAS layer (superficial musculoaponeurotic system — the deep support layer of the face), a similar tissue layer addressed in surgical facelift procedures, though HIFU itself is a non-surgical treatment and doesn’t replicate surgical-grade results.
The controlled heat from the ultrasound energy is designed to stimulate collagen response over time. This may produce a gradual tightening and lifting effect as the tissue remodels, with visible changes typically developing over time, though timelines vary between individuals.
HIFU is commonly considered for:
- Laxity along the jawline and lower face
- Heaviness at the brow or mid-face
- Softening of facial contours
- Loose skin at the neck or chin area
Suitability for HIFU depends on individual factors, including skin thickness, degree of laxity, tissue characteristics, and overall health.
Why These Two Treatments Are Sometimes Considered Together
Here is the key distinction that matters for this discussion:
- Rejuran Skin Booster (DEP) is designed to work at the skin surface level — addressing hydration, texture, and radiance.
- HIFU is designed to work at the structural tissue level — addressing lift, contour, and the deeper process of collagen remodelling over time.
Because they work at fundamentally different depths and target different problems, one doesn’t replace the other. A patient with only skin dullness and dehydration may find the skin booster relevant to their concern without needing HIFU. A patient with only tissue laxity may find HIFU more relevant. But skin ageing rarely presents as a single issue.
Many adults notice that multiple things have changed at once: skin quality has declined, and some structural laxity has set in. When both concerns are clinically present, a doctor may assess whether a care plan addressing both layers is appropriate and in what sequence.
What a Structured Plan Including Both Can Look Like
The two treatments are typically not performed on the same day. The sequencing and timing are determined by the doctor based on individual assessment.
Rejuran Skin Booster (DEP) sessions are generally spaced a few weeks apart, with improvement building gradually. HIFU results also develop over time, and the lifting and tightening effect from collagen remodelling may become more visible over the weeks and months following the procedure.
Because both treatments work gradually rather than producing immediate structural change, a realistic understanding of the treatment timeline — and of what each treatment can and cannot achieve — is an important part of any responsible consultation at ClearSK.
Combined Plan: Rejuran Skin Booster (DEP) + HIFU
| Rejuran Skin Booster (DEP) + HIFU | |
|---|---|
| Downtime | Minimal to none |
| Who it suits best | Those with concurrent surface-level concerns (dehydration, dullness, uneven texture) and early laxity along the jawline or mid-face |
| Pain level | Minimal for the skin booster; mild discomfort for HIFU, may be eased with numbing cream |
| Results-onset speed | Skin booster changes build across sessions; HIFU results develop over weeks to months |
| Longevity | Skin booster support may involve periodic follow-up; HIFU effects may last a period of months |
| Cost per month of result | Varies by number of sessions for each treatment; a personalised quote is provided at consultation |

How These Two Treatments Are Considered Together at ClearSK
When a clinical assessment identifies both skin quality decline and early tissue laxity, a doctor at ClearSK may structure a care plan that addresses each layer. Two approaches that commonly arise in this context are:
- Salmon-DNA-derived skin booster (DEP) + Korean HIFU: for patients presenting with concurrent surface-level concerns (dehydration, dullness, uneven texture) and early laxity along the jawline or midface. The topical skin booster addresses surface renewal; the focused ultrasound component addresses the deeper SMAS tissue layer.
- Surface-level renewal + focused ultrasound tissue remodelling: for patients managing both radiance/hydration concerns and structural tightening needs, where a clinician determines both are appropriate to consider.
Sequencing, session intervals, and the specific protocol depend on each individual’s assessment. Neither approach is a default recommendation — both require a clinical consultation to determine suitability.

Which Is Relevant for You?
- Mainly concerned about skin quality? If your concerns are dullness, dehydration, fine lines, or uneven texture, Rejuran Skin Booster (DEP) may be considered as part of a clinical discussion.
- Mainly concerned about facial support? If you’re noticing a softer jawline, early tissue laxity, or reduced facial definition, HIFU may be considered depending on your clinical assessment.
- Experiencing both? If both skin quality changes and early tissue laxity are present, a consultation can help determine whether a treatment plan addressing both concerns is appropriate.
