How Many Rejuran Sessions Do I Need To See Noticeable Results And How Long Do The Effects Last?

Rejuran eye treatment consultation at MD Cosmetic Nurse in Sydney

One of the most common questions patients ask during a consultation is: “How many Rejuran sessions do I need before I see a difference?” It is recommended to have 3 treatments spaced 2-4 weeks apart for optimal results.

Results are more subtle and develop gradually over time after the 3 treatments. Unlike treatments that may create immediate changes in appearance, Rejuran is generally considered a skin quality treatment. Results requires selecting the right patient and having realistic expectations with treatment outcomes. Maintenance treatments are generally recommended every 6 months.

You can learn more about Rejuran and consultation considerations on the Rejuran page.

Understanding what Rejuran can and cannot achieve is often the key to patient satisfaction.


What Is Rejuran Designed To Do?

Rejuran is commonly discussed in relation to skin quality concerns.

Patients often seek consultation for concerns such as:

  • Under-eye skin quality
  • Fine lines
  • Dull or tired-looking skin
  • Skin texture
  • General skin rejuvenation

Unlike treatments that restore volume or address facial movement, Rejuran does not add volume and is not designed to create dramatic changes in facial shape or structure.

Patients interested in concerns related to facial support and volume loss may wish to learn more about Volume Loss Consultations.

Similarly, concerns relating to facial movement and dynamic lines may be discussed during Wrinkle Reduction Consultations.


How Many Rejuran Sessions Are Usually Recommended?

Most patients are recommended a series of three treatments.

These sessions are typically performed:

  • 2–4 weeks apart
  • over approximately 6–12 weeks

One of the biggest misconceptions about Rejuran is expecting noticeable results after a single session.

While some patients may notice subtle changes earlier, most noticeable improvements are typically observed after completing the recommended series.

For this reason, completing all three treatments is often important when assessing whether the treatment has achieved the desired outcome.


When Do Patients Usually Notice Results?

Most patients begin noticing changes a few weeks after their third treatment.

The improvements are often subtle rather than dramatic.

Common feedback from patients includes:

  • Brighter-looking skin
  • Improved under-eye skin quality
  • Healthier skin appearance
  • Improved overall skin quality

Interestingly, many patients report that they cannot necessarily identify a dramatic change themselves.

Instead, friends or family may comment that their skin looks refreshed, healthy or well-rested without being able to identify exactly what has changed.

This reflects the subtle nature of skin quality treatments.


Why Some Patients Feel Rejuran “Didn’t Work”

One of the most common reasons patients become disappointed is that they stop after a single session.

This can happen because:

  • The treatment can be uncomfortable despite numbing cream
  • Temporary bumps or papules may remain visible for up to three days
  • Patients expect immediate results
  • Time and financial commitments make completing a series difficult

In some cases, patients complete only one treatment and later conclude that the treatment did not work.

In other cases, patients complete all three treatments but compare the outcome to treatments that create immediate changes in volume or facial shape.

Because Rejuran works differently, expectations need to be aligned with the treatment goals from the beginning.


What Rejuran Cannot Do

Setting realistic expectations is one of the most important parts of consultation.

Rejuran does not:

  • Remove excess skin
  • Replace surgery
  • Create significant volume
  • Lift sagging tissue
  • Produce dramatic overnight changes

For patients with significant skin laxity or excess skin, alternative approaches may be more appropriate.

This does not mean Rejuran will not stimulate collagen production, but it does mean that expectations must be realistic regarding what improvement may be achieved.


How Long Do Rejuran Results Last?

Results are not permanent.

In clinical practice, many patients choose maintenance treatments approximately every six months.

This is because the ageing process continues naturally over time.

Collagen production gradually declines as we age, and ongoing maintenance may help support skin quality over the longer term.

However, longevity can vary between individuals depending on factors such as:

  • Age
  • Skin quality
  • Lifestyle factors
  • Sun exposure
  • Smoking
  • General skin health
  • Adherence to skincare

Does Rejuran Replace A Skincare Routine?

No.

Rejuran should be viewed as one component of an overall skin health strategy.

It does not replace:

  • Cleansing
  • Makeup removal
  • Exfoliation
  • Moisturising
  • Daily sun protection
  • Professional skin treatments

Maintaining a consistent skincare routine remains important regardless of any cosmetic treatment plan.

Why Consultation Is Important Before Rejuran

Not every patient is an ideal candidate for Rejuran.

A consultation should assess:

  • Skin quality
  • Medical history
  • Previous treatments
  • Treatment goals
  • Expectations
  • Pain tolerance

Pain tolerance is often overlooked but can be an important consideration. Each individual has a different pain threshold. This must be discussed during your consultation.

Although many patients tolerate treatment well, some individuals with a very low pain threshold may find alternative treatment options more suitable.

The goal of consultation is not simply determining whether someone can have treatment, but whether it is likely to be the most appropriate option for their concerns and expectations.


A Consultation-Led Approach

At MD Cosmetic Nurse, consultations focus on understanding the individual’s skin concerns, anatomy, treatment goals and expectations before discussing potential treatment pathways.

Because skin quality concerns can arise from multiple factors, there is rarely a single solution that suits everyone.

A personalised consultation helps determine whether Rejuran, skin hydration approaches, volume loss assessment or other options may be most appropriate for the individual.

How Skin Quality Changes With Age (And Why Hydration Matters)

Skin ageing is often associated with wrinkles or volume changes, but skin quality itself plays a significant role in how the face looks over time. Changes in hydration, collagen, and barrier function can affect texture, elasticity, and overall skin appearance, even when facial structure remains relatively stable.

Understanding how skin quality changes with age helps guide appropriate assessment and personalised aesthetic care.

How Skin Changes Over Time

Skin ageing is influenced by both intrinsic factors, such as genetics and biological ageing, and extrinsic factors, including sun exposure and environmental stressors. These influences affect the skin at multiple levels.

Decline in Collagen and Elastin

As we age, collagen production slows and existing collagen fibres break down. Elastin, which allows skin to stretch and recoil, also becomes less resilient. This can lead to reduced firmness and increased skin fragility.

Reduced Hydration and Barrier Function

Ageing skin often has a reduced ability to retain moisture. Changes in the skin barrier can result in dryness, dullness, and increased sensitivity, making the skin appear less smooth and less luminous.

Slower Cellular Turnover

Cell renewal slows with age, which can contribute to uneven texture and a lack of radiance. This can make fine lines and surface irregularities more noticeable.

Why Hydration Is More Than Just Moisture

Hydration is not only about surface dryness. Adequate hydration supports skin elasticity, barrier integrity, and overall skin function. When hydration is compromised, the skin may appear thinner, rougher, or more prone to irritation.

Assessment of skin hydration and quality allows underlying contributors to be identified, rather than focusing solely on visible changes.

Skin Quality and Facial Ageing

Skin quality interacts closely with other ageing processes. Reduced hydration and elasticity can exaggerate the appearance of volume loss, shadowing, and textural irregularities.

A comprehensive facial assessment considers:

  • Skin thickness and elasticity
  • Hydration levels
  • Texture and tone
  • Interaction with underlying facial structure

This layered approach supports more appropriate and individualised care planning.

The Role of Consultation in Skin Quality Concerns

Because skin quality varies significantly between individuals, consultation-led care is essential. A consultation provides time to assess skin characteristics, discuss contributing factors, and explore appropriate options based on suitability and goals.

In some cases, treatments designed to support skin hydration and quality may be discussed as part of a broader aesthetic plan.

Final Thoughts

Skin ageing is a gradual process influenced by hydration, collagen integrity, and barrier function. Addressing skin quality as part of a personalised aesthetic consultation allows for a more comprehensive approach to facial ageing.

If you’re considering aesthetic care, a consultation provides an opportunity for a personalised assessment, discussing suitability, treatment options, and individual considerations.

Frequently Asked Questions

How does skin quality change with age?

Skin quality changes due to reduced collagen and elastin, decreased hydration, and slower cell turnover. These factors can affect texture, elasticity, and overall appearance.

Is dehydrated skin the same as dry skin?

No. Dehydrated skin refers to a lack of water within the skin, whereas dry skin is a skin type characterised by reduced oil (lipid) production. Dehydrated skin can occur in any skin type, including oily or combination skin, and may fluctuate due to factors such as environment, lifestyle, or ageing.

Why is hydration important for skin health?

Hydration supports skin elasticity, barrier integrity, and resilience. Adequate hydration helps maintain smoother texture and overall skin function.

Can skin quality affect the appearance of facial ageing?

Reduced skin quality can accentuate fine lines, uneven texture, and shadowing, particularly when combined with volume or structural changes.

Why is a consultation important for skin concerns?

A consultation allows for assessment of skin characteristics and contributing factors, supporting personalised recommendations rather than generic solutions.

4 Causes of Under-Eye Dark Circles and Treatment Options

Dark circles under the eye area, including the tear troughs, are a common concern and can be influenced by a range of anatomical and skin-related factors. Importantly, not all dark circles are caused by the same underlying issue, which is why a thorough assessment is essential before discussing potential management options.

Research into the causes of under-eye dark circles suggests that one or more contributing factors may be present at the same time. Understanding these factors helps guide appropriate consultation, education, and treatment planning where suitable.

A published clinical review identified four primary contributors to the appearance of dark circles under the eyes.

1. Hyperpigmentation

Hyperpigmentation refers to increased melanin in the skin beneath the eyes, which can create the appearance of darkening. This effect may be more noticeable when pigmentation occurs over prominent or bulging orbital fat pads, leading to increased shadowing.

Individuals with Fitzpatrick skin types IV, V, and VI are more commonly affected by pigmentation-related dark circles. In these cases, skin tone and pigment distribution play a significant role in overall appearance.

Management approaches for pigmentation concerns are discussed during consultation and depend on individual skin type, history, and suitability.

2. Thin or Translucent Under-Eye Skin

The skin beneath the eyes is naturally thinner than other areas of the face. When this skin becomes particularly thin or translucent, underlying vascular structures may become more visible, contributing to a darker appearance.

These vascular structures may include vessels within the subcutaneous tissue or the orbicularis oculi muscle. In some individuals, this anatomical feature is genetic, while in others it may become more apparent with age.

A consultation allows for assessment of skin thickness, vascular visibility, and contributing anatomical factors.

3. Skin Laxity and Shadowing

Ageing, sun exposure, and collagen breakdown can lead to reduced skin elasticity and firmness. As the skin becomes looser, shadowing beneath the eyes may increase, giving the appearance of dark circles even when pigment or vascular changes are minimal.

Assessment of skin quality and laxity forms part of a comprehensive facial evaluation, particularly when under-eye concerns are present.

4. Volume Changes and Tear Trough Hollowing

Changes in facial volume over time can contribute to hollowness beneath the eyes, commonly referred to as a tear trough. This may be influenced by subcutaneous fat loss in the cheeks, skin thinning, and ligamentous changes associated with ageing.

In some cases, displacement or prominence of orbital fat pads can further accentuate shadowing and contrast in the under-eye area. These volume-related changes are typically assessed as part of a broader facial volume and ageing consultation.

Why Assessment Matters

Because under-eye dark circles can result from multiple overlapping factors, management is rarely one-dimensional. A personalised consultation allows for detailed assessment of skin quality, anatomy, pigmentation, volume changes, and individual concerns.

This assessment-based approach supports informed discussion about suitability, expectations, and appropriate options, rather than applying a one-size-fits-all solution.
