The Truth About Collagen Loss After 40; and How to Naturally Boost It

 

Written by an independent, certified dermatologist

 

Collagen is often called the “building block” of youthful skin - and for good reason. It’s the protein that keeps skin firm, plump, and smooth. But after the age of 40, collagen levels begin to drop noticeably, leading to fine lines, wrinkles, and sagging, particularly around the eyes, jawline, and neck.

The good news? There are science-backed ways to stimulate collagen production naturally - without needles, surgery, or harsh treatments.

In this post, we’ll explore why collagen declines, what that means for your skin, and the habits, nutrients, and technologies that can help restore it.


What Is Collagen and Why Does It Matter?

Collagen is the most abundant protein in your body, making up about 75% of your skin’s structure. It keeps your skin elastic, hydrated, and firm. In your 20s and 30s, collagen production remains strong. But by your 40s, your body produces about 1% less collagen per year - and by menopause, that drop becomes more rapid.

Visible effects of collagen loss after 40:

  • Fine lines around the eyes and mouth
  • Deeper wrinkles on the forehead and cheeks
  • Sagging skin around the jawline and neck (“turkey neck” and jowls)
  • Thinner, drier, more fragile skin


Why Does Collagen Decrease with Age?

Several factors contribute to natural collagen decline:

  • Hormonal shifts, especially during perimenopause and menopause
  • UV damage from years of sun exposure
  • Oxidative stress caused by pollution and lifestyle habits
  • Decline in fibroblast activity, which are the cells responsible for collagen production

Knowing what causes collagen breakdown is the first step to preventing further loss - and encouraging your body to make more of it.


Natural Ways to Support Collagen Production

You don’t need expensive or invasive treatments to get results. Here are dermatologist-approved strategies that can help stimulate collagen safely and naturally:


1. Red & Near-Infrared LED Light Therapy

Red light (630–660nm) and deep-infrared light (680–780nm) are two of the most effective non-invasive treatments for boosting collagen.

These wavelengths penetrate deep into the skin, stimulating fibroblasts to produce more collagen and elastin. They also increase circulation, improving oxygen and nutrient delivery to the skin.

Bonus tip: Devices like the Dermaglow LED & EMS Mask combine red and deep-infrared modes to target deeper layers of the skin - improving tone, firmness, and the appearance of deep wrinkles over time.


2. EMS (Electrical Muscle Stimulation)

EMS helps tone and lift facial muscles, improving facial contours and reducing the appearance of sagging skin. Stronger underlying muscle tone gives the skin a firmer, more lifted appearance - particularly helpful for areas like jowls, cheeks, and neck.

Pairing EMS with red and infrared light amplifies the benefits of both, making this combo especially powerful for mature skin.


3. Use Retinol-Based Products

Retinol (a vitamin A derivative) is a gold-standard ingredient for boosting collagen. It works by increasing cell turnover and triggering your skin to produce more collagen and hyaluronic acid. Over time, it helps to reduce fine lines, improve texture, and strengthen thinning skin.

Use retinol at night, and always follow with SPF during the day - your skin becomes more sensitive to sun exposure while using it.


4. Eat Collagen-Supportive Foods

What you eat has a major impact on your skin’s ability to rebuild collagen. Try to include foods rich in:

  • Vitamin C – found in citrus, berries, and peppers. Essential for collagen synthesis.
  • Zinc – in nuts, seeds, and whole grains. Supports skin healing.
  • Amino acids – like glycine and proline, found in bone broth, eggs, and legumes.
  • Antioxidants – dark leafy greens and green tea help fight collagen-destroying free radicals.


5. Hydrate - Inside and Out

Hydrated skin looks plumper and more youthful. As collagen levels drop, skin loses its ability to retain moisture. Boost hydration with:

  • Hyaluronic acid serums to draw water into the skin
  • Ceramide-based moisturisers to seal in moisture
  • Plenty of water intake throughout the day to support overall skin health


6. Lower Stress and Sleep Well

Chronic stress increases cortisol, which breaks down collagen and triggers inflammation. Lack of sleep also disrupts your body’s natural repair process.

Try adding mindfulness habits like meditation, gentle yoga, or even just better sleep hygiene to give your skin a chance to recover.


Key Takeaways

Collagen loss is a natural part of ageing - but that doesn’t mean you can’t do anything about it. With smart, consistent habits and science-backed tools, you can support your skin’s natural ability to rebuild and stay youthful.

Here’s a quick recap:

  • Red, near-infrared & deep-infrared LED light boost collagen from deep within
  • EMS improves facial tone and lifts sagging areas
  • Retinol stimulates collagen and refines skin texture
  • A nutrient-rich diet fuels your skin from the inside
  • Hydration and stress management help maintain long-term results


Final Thoughts

Your skin may be changing - but with the right tools, it can still be radiant, resilient, and full of life. Whether you're noticing your first signs of sagging or dealing with stubborn lines, combining lifestyle changes with clinically proven technologies like LED and EMS can make all the difference.

Consistency is key - and your skin will thank you.
