Growth Factors In Skin Creams: 5 Key Benefits For Your Skin

What are growth factors?

**Growth factors** are proteins that regulate cellular growth, proliferation and differentiation under controlled conditions. They play an essential part in maintaining healthy skin structure and function.

These naturally occurring signalling molecules are secreted by various cells in the body, including skin cells, and act on specific receptors to mediate communication pathways crucial for tissue repair, maintenance, and rejuvenation.

Cells in ageing skin make fewer growth factors than cells in youthful skin. One approach to support the levels of skin rejuvenation is to regularly use skin care products with a high concentration of stable growth factors.

Purpose in skin creams

Topical skin creams containing endogenous growth factors are used as cosmeceuticals to reverse the signs and symptoms of skin ageing. They provide the skin with signalling molecules that mimic the body’s natural repair processes, promoting healthier skin architecture.

In intrinsic skin ageing (chronological ageing due to genetics and time), growth factor creams target:

• Thinning of the epidermis and dermis
• Loss of collagen, elastin, and glycosaminoglycans
• Reduced skin cell turnover
• Decreased vascularity

In extrinsic skin ageing, external factors like ultraviolet radiation from sun exposure and tobacco smoke cause degradation of collagen and other matrix components, leading to:

• Photoageing with deep wrinkles
• Leathery texture
• Solar elastosis (elastin degradation)
• Pigmentation irregularities
• Precancerous lesions

Controlled clinical studies have shown that the application of skin creams containing growth factors can improve these signs by stimulating collagen production, enhancing hydration, and reducing inflammation.

Do growth factors work?

There’s debate among dermatologists as to whether topically applied growth factors can penetrate the skin enough to be effective. It has been asserted that growth factors have a large molecular size that prevents them from entering the epidermis.

However, several clinical studies over the past 15 years have highlighted the benefits of topically applied growth factor products, showing improvements in the appearance of fine lines, wrinkles, texture, and discolouration.

Combinations of growth factors with antioxidants (e.g., vitamin C) and peptides (e.g., cytokines) tend to show results sooner, typically within 4–8 weeks.

The prevailing hypothesis is that when growth factors are applied to the skin in high concentrations, a small fraction penetrates the superficial epidermis and initiates a communication chain that leads to stimulation of dermal fibroblasts to produce collagen. Even minimal penetration can trigger amplified natural signalling between skin layers.

Source of growth factors

Advances in biotechnology over the past decade have created multiple sources of growth factors. They can be derived from:

• Human cells grown in a laboratory (skin cells, bone marrow stem cells, fat stem cells)
• Extracted from one’s blood (PRP – Platelet Rich Plasma)
• Bioengineered from non-human sources such as snails and some plants

However, fat stem cells are likely to produce growth factors that help the functioning of fat cells, and bone marrow stem cells are likely to produce growth factors that improve the functioning of the bone marrow. Ideal growth factors for the skin would be produced by fibroblasts.

In a comparative study published in 2017, dermal growth factors outperformed growth factors derived from other kinds of human stem cells (like fat cells) as well as non-human sources (such as snails and plants).

Companies like Neocutis SA (Switzerland) and Defenage (Carlsbad, California, USA) have developed products containing a mix of proprietary and non-proprietary peptides that stimulate the production of one’s own internal growth factors instead of adding growth factors externally.

How do they work?

Human growth factors are messengers received by specific receptor sites on the surface of skin cells, stimulating cell division and multiplication. For example, transforming growth factor (TGF) stimulates collagen production, and epidermal growth factor stimulates skin-cell production.

Growth factors connect with cell membrane receptors, initiating a cascade that promotes cell growth, differentiation, proliferation, and repair. This supports collagen and elastin synthesis, vascularisation, and reduces inflammatory responses.

When used in conjunction with procedures like needling, laser resurfacing, fractional resurfacing, or injections, growth factors are more effective than creams alone, accelerating healing and enhancing outcomes.

Uses of creams containing growth factors

Skin creams containing a physiologically balanced mixture of growth factors and other proteins are available to address:

• Post-procedure recovery: Accelerate healing after lasers, peels, or microneedling by boosting repair processes.
• Daily anti-ageing: Prevent and reverse fine lines, improve firmness, and even skin tone.
• Sensitive skin support: Safe for sensitive skin, promoting regeneration without irritation.

Controlled clinical studies demonstrate that consistent application leads to measurable improvements in wrinkle depth, skin elasticity, and pigmentation within weeks.

Effects

Topical growth factor creams have been shown to:

• Reduce fine lines and wrinkles
• Improve skin tone and texture
• Increase collagen and elastin production
• Enhance hydration and barrier function
• Diminish hyperpigmentation and redness

Several topical skin creams contain a single growth factor or multiple growth factors and cytokines, available over the counter. They may also include soluble collagen, matrix proteins, and antioxidants to neutralise free radicals. None are FDA approved as drugs, but they are widely used as cosmeceuticals.

Some growth factors used in skin creams

Commercially available growth factors

Several brands offer growth factor-infused products:

• SkinMedica TNS Recovery Complex®: Contains 93.6% dermal growth factors from cultured fibroblasts (neonatal foreskin-derived medium, no tissue present).
• Neauvia NLINE Advanced Cream: Multitasking peptides boosting collagen, elastin, and repair.
• Neocutis and Defenage products: Peptide blends stimulating endogenous growth factor production.

These are formulated for stability and efficacy in daily routines.

Safety of human growth factors

Human-derived growth factors in skincare have an excellent safety profile. They are naturally occurring in the body and, when topically applied, pose minimal risk. No significant adverse effects reported in clinical use.

Products are tested for purity, avoiding active pathogens. Suitable for long-term use, even on sensitive skin. Always patch-test new products and consult dermatologists for personalised advice.

Frequently Asked Questions (FAQs)

What are growth factors in skincare?

Growth factors are proteins that signal skin cells to grow, repair, and produce collagen, countering age-related decline.

Do topical growth factors penetrate the skin?

A small fraction penetrates to trigger fibroblast activity, amplified by natural skin signalling.

How long until I see results from growth factor creams?

Typically 4–8 weeks with consistent use, faster when combined with antioxidants or procedures.

Are growth factors safe for all skin types?

Yes, they are safe and non-irritating, even for sensitive skin.

What’s the best source of growth factors for skin?

Fibroblast-derived growth factors are ideal, outperforming others in studies.
