Collagen in Skincare: What Actually Works — and What Doesn’t

Collagen has become one of the biggest buzzwords in beauty. You’ve seen it everywhere — collagen creams, powders, serums, even gummies promising to restore youthful firmness. But how much of it really works, and how can you actually support your skin’s natural collagen production?


At Pt78 Skin and Body, we believe in transparency, science, and results. That’s why we’re breaking down the myths surrounding collagen and showing you exactly which ingredients — from SkinCeuticals and Pt78 — are proven to make a difference.




What Is Collagen?



Collagen is the most abundant protein in your body — the framework that gives your skin structure, firmness, and elasticity. Think of it as scaffolding that keeps everything lifted and smooth.


As we age, collagen production naturally slows down. Sun exposure, stress, poor sleep, and lifestyle factors accelerate this decline, leading to fine lines, sagging, and a loss of youthful volume. The good news? With the right topical ingredients, you can stimulate your skin’s ability to create new collagen — no needles required.




The Truth: Collagen Can’t Be Absorbed Through the Skin



Here’s the catch — collagen molecules are too large to penetrate the skin’s surface. That means creams or serums claiming to “add collagen” directly to your skin can’t physically do that.


Instead, effective collagen skincare works by stimulating your skin to produce more of its own collagen. This is achieved through ingredients that trigger fibroblast activity (the cells that make collagen), reduce inflammation, and protect existing collagen from breakdown.


The best approach is threefold:


  1. Stimulate new collagen synthesis.

  2. Protect existing collagen from UV and oxidative stress.

  3. Hydrate and plump the skin barrier.





SkinCeuticals: Proven Collagen Stimulation Through Science



Few brands rival SkinCeuticals when it comes to clinically proven collagen support. Their formulations don’t just moisturise — they transform skin function at a cellular level.



1. Vitamin C — The Antioxidant Powerhouse



The cornerstone of SkinCeuticals’ philosophy is antioxidant protection, and Vitamin C is the hero ingredient. It not only brightens the skin but also activates collagen synthesis.


Try:





2. Peptides — The Collagen Messengers



Peptides send direct signals to your skin to boost collagen production. They act like cellular instructions, telling the skin it’s time to repair and rebuild.


Try:





3. Lipid Restoration and Barrier Repair



Collagen synthesis is supported by healthy lipids that maintain moisture balance. Without hydration, even collagen-rich skin can look dull and tired.

Pt78: Natural Collagen Support from Within



While SkinCeuticals focuses on high-performance actives, Pt78 Skin and Body takes a complementary approach with vegan, naturally active ingredients that help the skin retain hydration and maintain firmness.



Botanical Peptides and Natural Vitamins



Plant-derived peptides, Vitamin B3 (Niacinamide), and antioxidants work synergistically to strengthen your skin’s structure while respecting its natural rhythm.


Try:




Together, these products provide a cruelty-free way to achieve visible firmness and glow without synthetic additives.




Ingredients That 

Actually

 Boost Collagen



To truly support collagen health, look for these ingredients in your skincare:


  • Vitamin C (L-ascorbic acid): Stimulates new collagen synthesis.

  • Peptides: Encourage fibroblast activity.

  • Retinol: Speeds up cell turnover, allowing new collagen to form.

  • Niacinamide (Vitamin B3): Strengthens the skin barrier and improves elasticity.

  • Hyaluronic Acid: Plumps the skin and supports structural integrity.

  • Antioxidants: Protect collagen from environmental breakdown.



You’ll find these ingredients across the Prevent + Correct Collection at Pt78, as well as in the full SkinCeuticals range.




Ingredients That Don’t Boost Collagen (Despite the Hype)



It’s important to be realistic — some products make claims that sound great but don’t hold up under scientific scrutiny.


  • Topical collagen: Can’t penetrate deep enough to stimulate production.

  • Collagen powders and gummies: While beneficial for general health, their direct effect on skin firmness is modest and inconsistent.

  • Plant collagen: Doesn’t exist in the same form as human collagen, though it may hydrate the skin superficially.



Instead, focus on collagen-supporting actives that work within your skin rather than sitting on top of it.
