ZO Skin Health® Growth Factor Serum

ZO Skin Health® Growth Factor Serum is an advanced age-management serum powered by five safely synthesised, human-comparable growth factors. The next-generation formula delivers targeted skin-signalling technology to improve the visible appearance of skin density, elasticity, firmness and smoothness.

Developed for skin showing moderate to advanced signs of ageing, this sophisticated 30ml serum supports a thicker, more supple and better-hydrated appearance while temporarily reducing the look of expression lines. In ZO Skin Health’s reported clinical assessment, skin appeared nearly six years younger on average after eight weeks of twice-daily use.

Next-Generation ZO Growth Factor Technology

Growth factors are specialised signalling proteins involved in communication between cells. Within skincare, carefully formulated growth-factor technology is used to support the processes associated with healthier-looking, more resilient skin.

The new generation of ZO Growth Factor Serum uses five safely synthesised growth factors designed to be comparable with signalling proteins naturally present in human skin. This allows the formulation to target several visible characteristics associated with skin ageing rather than addressing surface hydration alone.

The five-factor system includes:

• Epidermal Growth Factor (EGF) — supports signalling associated with epidermal renewal and a smoother-looking skin surface.
• Insulin-Like Growth Factor 1 (IGF-1) — contributes to the formula’s support for skin density, resilience and visible vitality.
• Acidic Fibroblast Growth Factor (aFGF) — forms part of the signalling complex directed towards firmer and more supple-looking skin.
• Basic Fibroblast Growth Factor (bFGF) — complements the serum’s approach to visible skin thickness, elasticity and structural quality.
• Vascular Endothelial Growth Factor (VEGF) — completes the five-factor technology supporting a healthier and more revitalised appearance.

Together, these human-comparable growth factors provide a coordinated signalling system developed to improve the visible qualities that commonly decline with age: thickness, elasticity, firmness, smoothness and suppleness.

Why Skin Density and Elasticity Matter

Ageing skin can gradually appear thinner, less resilient and more visibly creased. Changes in its supporting structure, hydration and natural renewal processes may contribute to expression lines, uneven texture and a loss of firmness.

ZO Growth Factor Serum is designed to address this broader pattern of visible ageing. Its objective is not simply to soften the surface temporarily, but to support skin that progressively appears denser, smoother, firmer and more elastic with consistent use.

This makes it particularly relevant when the complexion has begun to look less substantial or when conventional hydration alone no longer provides the desired improvement in visible skin quality.

Clinically Assessed Age-Management Benefits

ZO Skin Health evaluated the next-generation Growth Factor Serum in an independent, third-party clinical study involving 46 women aged 44 to 74. Participants had moderate to severe visible signs of ageing and represented Fitzpatrick skin types II to VI.

The serum was used twice daily for 12 weeks alongside Gentle Cleanser and Sheer Fluid Broad-Spectrum Sunscreen SPF 50. ZO reports that after eight weeks:

• Skin showed visible improvement in thickness and elasticity
• Skin appeared smoother and more supple
• Hydration and visible firmness improved
• Expression lines appeared temporarily reduced
• Skin appeared nearly six years younger on average according to subject assessments

The “six years younger” figure is based on the average assessment recorded within the study rather than a guaranteed result for every individual. Continued and consistent use within a professionally selected skincare programme is important.

Who Is ZO Growth Factor Serum For?

ZO Growth Factor Serum is suitable for all skin types and may be particularly relevant for people concerned about:

• Visible loss of skin firmness
• Reduced elasticity or resilience
• Thin or fragile-looking skin
• Expression lines and visible creasing
• Uneven or rough-looking texture
• Loss of suppleness
• Dehydrated or less vibrant-looking skin
• Moderate to advanced visible signs of ageing
• Maintaining skin quality within a comprehensive ZO programme

Its multi-pathway approach makes it especially valuable where several signs of ageing are present together. A Skin By Science consultation helps establish its role alongside the other active products within an individual ZO protocol.

Texture and Finish

Growth Factor Serum has a refined gel-serum texture designed to distribute evenly across clean, dry skin. It provides hydration without behaving like a conventional heavy moisturiser and can be incorporated into both morning and evening programmes.

Its finish allows subsequent skincare and daytime sun protection to be layered according to the sequence selected for the individual.

Directions

1. Apply to clean, dry skin.
2. Distribute the serum evenly across the face and other areas included within the personalised programme.
3. Use morning and evening unless an alternative frequency has been recommended.
4. Follow with the remaining Prevent + Correct products selected for the ZO protocol.
5. Complete the morning programme with appropriate broad-spectrum sunscreen.

When Growth Factor Serum is being combined with retinol, exfoliating treatments or other high-activity ZO formulations, follow the product sequence and frequency established during consultation.

Its Role Within a ZO Skin Health Programme

ZO Growth Factor Serum occupies a targeted age-management position within the Prevent + Correct stage of a ZO programme. It concentrates on visible density, elasticity, firmness, smoothness and expression lines through advanced growth-factor signalling technology.

ZO Skin Health Daily Power Defence may provide complementary daily support for hydration, barrier resilience and environmental defence across the face. The two products have distinct roles and can be positioned together when appropriate within a professionally selected programme.

Daily broad-spectrum sun protection remains essential when addressing visible ageing. ZO Skin Health Sheer Fluid Broad-Spectrum SPF 50 can provide the final protective step where it has been selected for the individual’s routine.

Frequently Asked Questions

What does ZO Growth Factor Serum do?

It is designed to improve the appearance of skin thickness, density, elasticity, firmness and smoothness. It also supports hydration, restores a more supple appearance and temporarily reduces the look of expression lines.

What makes this the next-generation formula?

The current formula is powered by five safely synthesised, human-comparable growth factors. This replaces the older generation of Growth Factor Serum that was commonly described using plant-derived growth factors and ZPRO® technology.

Which growth factors does it contain?

ZO’s human-comparable growth-factor technology incorporates EGF, IGF-1, acidic FGF, basic FGF and VEGF. Together, they form a coordinated signalling complex developed to support younger-looking skin.

What does “human-comparable” mean?

It means the growth factors are safely synthesised to be comparable with naturally occurring human signalling proteins. The description does not mean that the ingredients are taken directly from human skin.

Does Growth Factor Serum contain human-derived material?

ZO describes the five growth factors as safely synthesised and human-comparable. They are used to deliver targeted signalling within the cosmetic formulation.

How quickly can visible results appear?

ZO reports clinically assessed improvements after eight weeks of twice-daily use. The supporting study continued for 12 weeks, and individual results can vary according to skin condition, consistency and the wider programme.

Can it really make skin look six years younger?

ZO reports that participants’ skin appeared nearly six years younger on average after eight weeks, based on subject assessments in its clinical study. This is an average study outcome rather than a guaranteed result for every user.

Is it suitable for all skin types?

Yes. ZO identifies Growth Factor Serum as suitable for all skin types. Consultation remains valuable because the wider programme should reflect individual skin condition, sensitivity and treatment objectives.

Is it non-comedogenic?

Yes. The current formulation is identified by ZO as non-comedogenic.

Can Growth Factor Serum be used morning and evening?

Yes. ZO directs the serum to be applied to clean, dry skin in the morning and evening as part of the selected Prevent + Correct programme.

Can it be combined with ZO retinol?

Growth Factor Serum can form part of a programme that also contains a ZO retinol. The strength, frequency and sequence of high-activity products should be selected around the individual’s skin tolerance and objectives.

Does it replace moisturiser?

It provides hydration, but its principal purpose is advanced growth-factor-led age management. Whether an additional hydration or barrier-supporting product is required depends on skin condition and the structure of the wider programme.

Does it replace sunscreen?

No. Growth Factor Serum is a corrective age-management serum. Appropriate broad-spectrum sunscreen should be applied as the final stage of the morning skincare programme.

Why is consultation required?

Skin By Science supplies ZO Skin Health following consultation so that Growth Factor Serum can be positioned correctly alongside other active products and selected according to the individual’s skin condition, tolerance and objectives.
