Hey friend,

Red Light Therapy for Collagen Production: Does It Really Work?

If you’re anything like me, you’re always on the lookout for ways to keep your skin looking fresh and glowing—whether it’s by drinking more water, slathering on face creams, indulging in masks, or eating certain foods like collagen-rich bone broth. Fighting back those fine lines and wrinkles is more and more of a challenge (at least for me these days!), so when I heard about red light therapy for collagen production, I had to dig in and see if it’s actually worth the hype.

I was getting a facial the other day, and my esthetician used both red and blue light therapy on me. That got me thinking—does this actually work, or is it just another fancy beauty gimmick? And is it worth dropping around $400 on an at-home red light therapy device? (Ouch!) So, I did some digging, and here’s what I found.

What Is Red Light Therapy?

Red light therapy (RLT) is a treatment that uses low-wavelength red light to penetrate the skin and promote healing, collagen production, and cell regeneration. It’s been around for a while—originally used by NASA to help astronauts heal wounds in space (cool, right?). Today, it’s a go-to for skin rejuvenation, reducing inflammation, and even easing muscle pain. It’s even used for reducing joint pain and improving circulation. Some people even claim that it helps with hair growth and reducing signs of aging on the scalp.

Does It Actually Work?

Studies suggest that red light therapy can help with:

• Boosting collagen production (hello, firmer skin!)
• Reducing fine lines and wrinkles
• Calming inflammation and redness
• Speeding up wound healing and reducing acne scars
• Enhancing overall skin tone and texture
• Easing muscle recovery and joint pain
• Improving circulation and reducing oxidative stress in cells
• May help with hair regrowth and reducing thinning hair

While it’s not a miracle cure, consistent use (like 3-5 times per week) over a few months can yield noticeable results. Dermatologists and estheticians swear by it, and at-home devices have gotten better in recent years.

Red Light Therapy vs. Blue Light Therapy—What’s the Difference?

If you’ve heard of blue light therapy too, here’s how they compare:

• Red Light Therapy: Targets deep skin layers to boost collagen, reduce wrinkles, and promote healing.
• Blue Light Therapy: Works more on the surface, killing acne-causing bacteria and controlling oil production.
• Some devices combine both to tackle multiple skin concerns at once!
• Near-Infrared Light Therapy: Sometimes combined with RLT to penetrate even deeper for pain relief and muscle recovery.
• Green Light Therapy: Less common, but can help with pigmentation and reducing dark spots.
• Yellow Light Therapy: Helps with reducing redness and boosting lymphatic flow.

Foods That Naturally Boost Collagen Production

• Bone broth – One of the best sources of natural collagen.
• Salmon & fatty fish – Packed with omega-3s that support skin health.
• Egg whites – Rich in proline, an amino acid essential for collagen production.
• Citrus fruits – Vitamin C is a must-have for collagen synthesis.
• Leafy greens – Full of antioxidants that protect collagen from breaking down.
• Berries – Rich in antioxidants and vitamin C.
• Nuts & seeds – Provide healthy fats and minerals that aid in collagen production.
• Garlic – Contains sulfur and taurine, which help prevent collagen breakdown.
• Avocados – Rich in vitamin E, which helps protect skin from oxidative stress.
• Tomatoes – Contain lycopene, which boosts skin protection from UV rays.

Tips for Getting the Most Out of Red Light Therapy

If you’re going to invest in an RLT device, here are some tips to maximize your results:

• Be consistent – You need to use it multiple times per week for at least a few months.
• Use it on clean skin – No makeup or sunscreen to get the best penetration.
• Follow the recommended time – Don’t overdo it, or you might cause irritation.
• Pair with skincare – Apply collagen-boosting serums like vitamin C afterward.
• Hydrate and eat well – Collagen production works best when your body has the right nutrients.

• Be patient – Results aren’t instant, but over time, you’ll notice improvements.
• Store your device properly – Keep it clean and charged for long-term use.

So… Is It Worth It?

If you’re serious about skincare and consistent with treatments, an at-home red light therapy device can be a great investment. But if you’re the type who buys beauty gadgets only to let them collect dust, you might want to book an occasional professional treatment instead.

At the end of the day, red light therapy isn’t just hype—it does have science backing it up. But like most things in skincare, results take time and consistency.
