Rejuran vs Profhilo: Which Treatment Should You Choose?

Rejuran vs Profhilo: Which Treatment Should You Choose?

Rejuran and Profhilo are two popular injectable skin-rejuvenation treatments used to improve skin quality without creating the pronounced facial volume associated with traditional dermal fillers. Although both are often called “skin boosters,” they use different ingredients and work through different mechanisms.

Rejuran uses polynucleotides (PN), while Profhilo uses a high concentration of hyaluronic acid (HA). Rejuran is generally associated with skin regeneration, elasticity, and texture improvement, while Profhilo focuses strongly on hydration, firmness, and overall skin remodeling.

Neither treatment is universally better. The right choice depends on whether your main concern is skin texture and resilience or hydration, firmness, and early laxity.

What Is Rejuran?

Rejuran is a Korean injectable treatment based on polynucleotides (PN) derived from purified salmon DNA. It is designed primarily to improve the condition and quality of the skin rather than add conventional filler-like volume.

Rejuran may be considered for:

• Fine lines and early wrinkles
• Reduced skin elasticity
• Thin or fragile-looking skin
• Uneven texture
• Enlarged-looking pores
• Dull or tired-looking skin
• Certain acne-scar-related concerns
• Under-eye skin quality

The treatment is generally associated with gradual changes in skin quality. Rather than creating an immediate lifting or volumizing effect, the goal is to support a healthier, smoother, and more resilient appearance over time.

What Is Profhilo?

Profhilo is an injectable treatment containing a high concentration of hyaluronic acid formulated for skin bio-remodeling. Unlike conventional HA fillers, it is not primarily designed to sculpt facial contours or add significant localized volume.

Profhilo is commonly considered for:

• Dehydrated skin
• Loss of firmness
• Early skin laxity
• Fine lines
• Crepey-looking skin
• Reduced elasticity
• Dull or tired-looking skin
• Overall skin quality

Its highly concentrated HA formulation is designed to distribute through the tissue and support hydration and dermal remodeling.

Profhilo is also commonly used on areas beyond the face, including the neck, décolletage, and hands, depending on the treatment plan.

Rejuran vs Profhilo: Main Difference

The biggest difference is the active ingredient and treatment objective.

Rejuran

• Active ingredient: Polynucleotides
• Primary focus: Skin regeneration and quality
• Particularly relevant to: Texture, fine lines, elasticity, thin skin
• Treatment style: Multiple small injections
• Result: Gradual improvement in skin condition

Profhilo

• Active ingredient: Hyaluronic acid
• Primary focus: Hydration and dermal remodeling
• Particularly relevant to: Dryness, firmness, early laxity
• Treatment style: A small number of strategically placed injection points
• Result: Hydrated, smoother, firmer-looking skin

Both can improve overall skin appearance, but they are not simply two versions of the same treatment.

Which Is Better for Skin Texture?

If texture and overall skin quality are your main concerns, Rejuran may be the better fit.

Rejuran can be considered when you have:

• Rough or uneven texture
• Fine lines
• Thin-looking skin
• Reduced elasticity
• Enlarged-looking pores
• Skin that appears stressed or damaged
• General age-related deterioration in skin quality

Profhilo can also make the skin appear smoother because improved hydration can soften the appearance of fine surface irregularities. However, its primary strength is hydration and remodeling rather than targeted skin repair.

For deeper acne scars or significant textural irregularities, neither treatment should automatically be considered a standalone solution. Scar-specific procedures may be more appropriate depending on the type and depth of the scar.

Which Is Better for Hydration and Glow?

For patients primarily looking for deep hydration, radiance, and a refreshed appearance, Profhilo may have an advantage.

Profhilo may be particularly appealing when the skin looks:

• Dry
• Dull
• Dehydrated
• Tight
• Less supple
• Lacking its natural glow

Rejuran can also improve the appearance of hydrated and healthy skin, but its main focus is broader skin-quality improvement rather than delivering a primarily hydration-focused effect.

If your main goal is the popular “glass skin” appearance associated with smoother, dewier-looking skin, a hyaluronic-acid-based treatment such as Profhilo may be considered.

Which Is Better for Firmness and Skin Laxity?

If early loss of firmness is your main concern, Profhilo may be particularly suitable.

Its HA-based bio-remodeling approach is designed to support the skin's hydration and structural environment while encouraging collagen and elastin-related remodeling.

It may be considered for:

• Early facial laxity
• Reduced skin bounce
• Crepey skin
• Loss of firmness
• Mild changes in facial skin quality
• Neck skin concerns

Rejuran can also improve elasticity and skin resilience, but it is generally selected more for skin quality and regenerative support than for a noticeable lifting effect.

Neither treatment should be considered a replacement for a surgical facelift or a dedicated energy-based lifting treatment when significant laxity is present.

Rejuran vs Profhilo for Fine Lines and Wrinkles

Both treatments may help improve the appearance of fine lines, but the underlying cause of the lines matters.

Rejuran may be preferable when:

• Fine lines occur with thin or fragile skin.
• Overall skin quality has declined.
• Texture is uneven.
• Elasticity has decreased.
• You want gradual skin regeneration and quality improvement.

Profhilo may be preferable when:

• Fine lines are associated with dehydration.
• Skin looks crepey or less supple.
• Firmness has decreased.
• You want a smoother, more hydrated appearance.
• Early laxity is also a concern.

Neither treatment directly addresses every type of wrinkle. Dynamic wrinkles caused by repeated facial muscle movement may require a different approach.

Rejuran vs Profhilo: Treatment Process

The injection techniques are noticeably different.

Rejuran Treatment

Rejuran is commonly administered through multiple small intradermal injections across the treatment area.

A typical session may involve:

1. Skin assessment
2. Cleansing and preparation
3. Topical numbing
4. Multiple small Rejuran injections
5. Post-treatment care

Small raised bumps, redness, and swelling can temporarily appear at the injection sites.

Profhilo Treatment

Profhilo is often administered using a small number of strategically selected injection points, commonly following a standardized BAP-style technique for facial treatment.

The process generally involves:

1. Skin assessment
2. Cleansing
3. Treatment planning
4. Profhilo injections at designated points
5. Brief post-treatment observation and aftercare

Because there are fewer injection points than with many traditional skin-booster techniques, some patients find the treatment process more convenient.

Rejuran vs Profhilo: Results and Treatment Frequency

The two treatments are often used according to different treatment schedules.

Rejuran

Rejuran is commonly performed as an initial series of several sessions.

A typical Korean protocol may involve:

• Around 2–4 initial sessions
• Several weeks between sessions
• Individualized maintenance afterward

The results tend to develop gradually as the skin responds to the treatment.

Profhilo

Profhilo is commonly performed as an initial two-session protocol, with the sessions generally separated by approximately four weeks.

Patients may then consider maintenance according to:

• Skin condition
• Age
• Lifestyle
• Degree of laxity
• Individual response
• How long the improvement remains noticeable

The exact schedule should be determined by the treating provider rather than following a fixed protocol for every patient.

Rejuran vs Profhilo: Downtime and Comfort

Both treatments involve injections, so temporary reactions are possible.

Common short-term effects include:

• Redness
• Mild swelling
• Small injection bumps
• Bruising
• Tenderness
• Temporary sensitivity

Rejuran often creates more visible small papules immediately after treatment because of the larger number of injection points.

Profhilo can also produce small raised areas at the injection sites, but these generally settle as the product disperses.

For international visitors, it is better to allow some flexibility after treatment rather than scheduling the procedure immediately before an important event, photoshoot, or long day of sightseeing.

Can You Combine Rejuran and Profhilo?

In some patients, a provider may consider combining or sequencing Rejuran and Profhilo because they address different aspects of skin aging.

A potential rationale is:

• Profhilo: hydration, firmness, and dermal remodeling
• Rejuran: skin quality, texture, and regenerative support

However, combining injectable treatments is not automatically better. The products, injection sites, and treatment timing need to be planned carefully.

A staged treatment plan may be more appropriate than performing multiple injectable procedures at the same time, particularly for patients with sensitive skin or significant injection-related swelling.

Which Treatment Is Better for Different Skin Concerns?

A simple guide can help narrow down the choice.

Rejuran May Be Better If:

• Your skin is thin or fragile.
• Fine lines and texture are your main concerns.
• You want to improve overall skin quality.
• You have enlarged-looking pores.
• Your skin has a stressed or damaged appearance.
• You want a gradual regenerative-style treatment.

Profhilo May Be Better If:

• Your skin is dry or dehydrated.
• You want more visible hydration and glow.
• Early skin laxity is a concern.
• Your skin looks crepey.
• You want improved firmness and suppleness.
• You prefer a treatment involving fewer injection points.

A Combination May Be Considered If:

• You have both dehydration and poor skin quality.
• You have reduced firmness together with fine lines and texture concerns.
• Your provider believes the treatments can complement each other.
• You prefer a staged long-term skin-rejuvenation plan.

The most appropriate choice depends on the condition of the skin rather than age alone.

Final Thoughts

Rejuran and Profhilo are both effective options for improving skin quality, but they target different aspects of skin aging. Rejuran uses polynucleotides and is generally associated with skin regeneration, texture, elasticity, and overall skin resilience. Profhilo uses hyaluronic acid and is particularly focused on hydration, firmness, and dermal remodeling.

If your main concern is thin skin, fine lines, texture, or overall skin quality, Rejuran may be the better choice. If you are primarily concerned with dehydration, loss of firmness, early laxity, and a lack of glow, Profhilo may be more suitable.

For patients with multiple concerns, a qualified provider may also consider a staged combination of the two. The best treatment is ultimately the one that matches your specific skin condition, treatment area, and desired outcome.
