What Are Growth Factors and Why Everyone's Talking About Them
Skin growth factors are emerging as the next major breakthrough in anti-aging skincare, positioned alongside the proven "core five" essentials: cleansers, moisturizers, retinoids, vitamin C serums, and sunscreen. These biotech actives work by sending signals to your skin cells, instructing them to repair, rebuild, and renew themselves. But as powerful as they are, growth factors come with important considerations you need to understand before adding them to your routine.
The Science Behind Growth Factors: From Nobel Prize to Your Bathroom Shelf
The journey of growth factors in skincare is rooted in serious scientific discovery. Between the 1950s and 1980s, researchers uncovered these powerful protein messengers, with epidermal growth factor (EGF) earning scientists a Nobel Prize. By 1999, SkinMedica pioneered bringing this laboratory science into consumer skincare products.
Over the following two decades, brands like Neocutis and BioEffect refined the technology. Most recently, The Ordinary democratized access with their 15% growth factor solution in 2025, making this cutting-edge ingredient available at an accessible price point of around $15 per ounce.
How Growth Factors Actually Work on Your Skin
Think of growth factors as text messages your skin cells send to each other. These tiny protein messengers deliver crucial instructions like "make more collagen," "repair the extracellular matrix," and "strengthen the skin barrier."
As we age, these cellular signals naturally fade and weaken. The result? Slower skin renewal, reduced collagen production, and visible signs of aging like fine lines and wrinkles. Topical growth factor serums aim to reignite this internal communication system, helping restore your skin's natural repair mechanisms.
When paired with retinoids, growth factors can be particularly effective at improving skin resilience and youthful appearance over time.
The Controversial Dark Side: What You Need to Know
Here's where growth factors get complicated. When you encourage cell growth and regeneration, you're potentially encouraging all cellular growth—including cells you might not want to stimulate.
The Risk Factor
Applying growth factors directly to problematic areas like moles, dark spots, actinic keratosis, or damaged skin zones could theoretically stimulate cells that shouldn't be encouraged to grow. While research is ongoing, this concern is significant enough to warrant caution.
How to Hedge Your Risk
To use growth factors safely and intelligently:
- Target healthy skin only: Apply to fine line zones like around the eyes, neck, forehead creases, and other areas without concerning features
- Avoid problem areas: Keep growth factors away from moles, unusual dark spots, actinic spots, or any area with drastic changes in color or texture
- Consult your dermatologist: If you have a history of moles, unusual skin changes, or skin cancer, get professional guidance before using growth factors

Are Growth Factors Right for You?
Growth factors aren't just hype—they're clinically validated ingredients with real scientific backing. Real-world testing shows promising results for improving skin texture, reducing fine lines, and supporting long-term skin health.
However, they're not for everyone. The theoretical risks, while not definitively proven, are worth considering, especially if you have concerning moles, spots, or a history of skin issues.
Best Candidates for Growth Factors:
- Those who've mastered the core five skincare essentials
- People looking for the next level in anti-aging
- Those with healthy skin seeking preventive care
- Anyone willing to use them strategically and carefully
Who Should Proceed with Caution:
- People with multiple or changing moles
- Those with a history of skin cancer
- Anyone with actinic keratosis or precancerous lesions
- Those who haven't consulted a dermatologist about concerns
The Bottom Line: Power Requires Responsibility
Skin growth factors represent a genuine advancement in anti-aging skincare technology. They're backed by decades of research, Nobel Prize-winning science, and clinical validation. Early personal testing shows they can deliver impressive results.
But with great power comes responsibility. These aren't ingredients to slather everywhere without thought. Use them intelligently, target healthy skin zones, avoid problem areas, and consult professionals when needed.
If you're already consistent with your core five skincare essentials and looking for the next frontier in skin health, growth factors might be your next weapon in the anti-aging arsenal—just wield them wisely.
