Collagen Supplements: Truth, Science & Skin Advice by Alan Araujo

The Truth About Collagen Supplements – Backed by Science and Experience

Collagen is one of the most talked-about beauty buzzwords of the last decade. You’ll find it in powders, gummies, protein shakes, even face masks. But let me ask you something: Do you really know what you’re buying?

With over half a decade of hands-on experience treating thousands of faces, backed by exceptional academic performance and multiple professional certifications, I’ve seen firsthand what truly supports healthy skin. I’m a Licensed Electrologist and Facial Specialist, a Licensed Massage Therapist (MA 107492), and the proud founder of Lux MedSpa Brickell. My training is certified and licensed by the Florida Board of Medicine, and I hold a Law degree from Pontifical Catholic University of Minas Gerais (PUC Minas) — the largest Catholic university in the world and one of the most recognized private institutions in Brazil. My expertise has been featured in USA News, Digital Journal, and Marquis Who’s Who

And let me tell you — no supplement can do the work of a full protocol.

In this article, I’ll break down the truth about collagen supplements, what the FDA says, and what actually works to protect and support collagen in your skin.

What Is Collagen, and Why Does It Matter?

Collagen is the most abundant protein in your body. It gives structure to your skin, bones, joints, and connective tissues. Your body makes it naturally — but production starts to decline in your mid-20s.

That’s when the supplements start calling your name. But do they work?

Are Collagen Supplements FDA Approved?

No. Collagen supplements are not FDA-approved to treat, prevent, or cure any condition. Most are classified as dietary supplements, which means they are not regulated with the same scrutiny as medications.

Translation: they don’t need to prove their claims before hitting the market.

According to the MD Anderson Cancer Center, one of the most respected medical institutions in the world, this lack of regulation means manufacturers are not required to demonstrate that their collagen products are safe or effective before putting them on shelves. While some may use “hydrolyzed collagen” or “collagen peptides,” the exact formulation, dose, and results are inconsistent across brands.

“There is little reliable data showing that over-the-counter collagen supplements have long-term benefits,” notes Dr. Susan Chon, M.D., a board-certified dermatologist at MD Anderson. “Collagen molecules are often broken down during digestion, meaning what you’re ingesting may not even reach your skin.”

This means consumers are largely relying on marketing rather than medical-grade science. Some brands cite small clinical studies, but most are funded by the manufacturers themselves. And even when benefits are noted, they’re often modest — certainly not the dramatic transformations promised by ads.

Bottom line? Without regulation or FDA oversight, anyone can market a collagen supplement with exaggerated claims. Always check for third-party testing, medical-grade backing, and consult your provider before starting any regimen.

The Marketing vs. The Science

Some studies suggest that hydrolyzed collagen (collagen peptides) may improve skin elasticity and hydration. But the data is still limited, and many of the “visible results” people experience come from lifestyle changes they make alongside the supplement.

For example:

• Drinking more water

• Sleeping better

• Using SPF daily

• Starting facials or new skincare

So the supplement gets the credit, but the real change is you showing up for your skin.

What Actually Destroys Collagen

Let’s stop blaming lack of supplements and talk about the real collagen killers:

• Sun damage (UVA/UVB rays)

• Smoking and pollution

• Excess sugar (glycation breaks down proteins)

• Alcohol, stress, and sleep deprivation

• Over-exfoliation or poor skincare habits

If you want to protect collagen, start here:

• Wear sunscreen every single day (yes, even indoors) - Make it a habit

• Stop over-cleansing or scrubbing your skin raw

• Feed your skin with nutrient-rich, clinical skincare like Cosmedix

• Use antioxidants like vitamin C, niacinamide, and peptides

My Honest Take as a Spa Founder

Clients come into Lux MedSpa Brickell all the time asking, “What’s the best collagen supplement?”

My answer?

Let’s Talk Nutrition: Because No Supplement Works Alone

Even the most high-quality collagen supplement won’t deliver lasting results without the right nutritional foundation. Collagen production in the body relies on a delicate balance of micronutrients that no powder alone can provide. If you're serious about supporting your skin from within, your plate matters just as much as your product shelf.

Here’s what your body actually needs to build and maintain collagen naturally:

• Vitamin C – Found in citrus fruits, strawberries, bell peppers; this antioxidant is essential for collagen synthesis.

• Vitamin A – Sweet potatoes, carrots, and spinach offer this vital nutrient that supports skin renewal and repair.

• Vitamin E – Almonds and sunflower seeds help protect skin from oxidative stress and cellular breakdown.

• Zinc – From chickpeas and pumpkin seeds, zinc plays a key role in tissue repair and collagen structure.

• Copper – Found in sesame seeds, mushrooms, and leafy greens like kale, copper helps form the collagen matrix.

But don’t stop at food alone.

Hydration, sleep, and daily sun protection are non-negotiable.

These are the pillars of real, visible skin health. Without them, collagen supplements become just another trend. With them, your skin can regenerate, strengthen, and glow — with or without a scoop of powder.

I say that with love — but with truth. Supplements are not magic. They're support tools. Your skincare, your lifestyle, your sun protection... those are the main characters.

If you’re going to spend money, do it on things that have real, clinical impact.

What I Recommend Instead

Want better collagen support? Build this into your daily routine:

• Double cleanse with an oil cleanser + exfoliating gel (Purity Solution + Purity Clean)

• Protect daily with Peptide-Rich Defense SPF 50

• Treat with peptides and antioxidants at night (Clarity, Cell ID, Pepoxide)

• Support internally with a diet rich in vitamin C, copper, zinc, and protein

• Book facials monthly with LED, lymphatic drainage, and metabolic peels

I believe you don’t need to chase a powder. You need to protect what you have.

Final Words

Collagen is important — but it’s not the whole story.

Your skin is smarter than any supplement label. It knows what to do. Give it the right tools, not empty promises. Think critical and smart about your diet and supplements, I always say that knowledge gives you freedom to choose what’s right or wrong for you.

If you're ready to support your skin collagen with real solutions, I strongly suggest you booking a custom facial at Lux MedSpa Brickell or explore our science-backed skincare and clean beauty line.
