The Complete Guide to Collagen

Collagen has been the talk of the skincare industry for quite a while now. There are many products available in the market that claim to increase collagen production. If you are deep into skincare and an anti-aging fanatic, you have probably heard of collagen already. It is basically a protein in our body that makes our skin look young and firm. But the catch is, there is a ticking timer on it. By the time we reach our mid-20s, the production of collagen in our body starts to decrease, and by the time we are in our 30s, the effects become more visible, and fine lines and wrinkles start appearing on our skin. So what exactly is collagen? Why do you need to start looking out for the lost collagen, and do the products available in the market really increase your collagen synthesis? Scroll down to find out.

What is collagen?

As mentioned, in simpler terms, collagen is what keeps our skin young and smooth. Who doesn’t want that? There are basically three main things that you need to know about collagen.

The top 3 benefits of collagen for your skin

1. Collagen keeps our skin plump: When collagen levels are high, as in our mid-20s, our skin is firm and bouncy. It’s what keeps the epidermis stretched and firm. But as expected, when there is less collagen or when it starts to decline, our skin starts to lose that bounce. That’s why we see sagging and fine lines on our skin. If you want to keep your skin lifted, you should watch out for your collagen.
2. Collagen keeps our skin hydrated by locking in moisture. When there is less collagen, our skin loses its ability to retain water. That’s why our skin becomes dry and flaky. You may also notice your complexion becoming dull.
3. The third benefit is a big one—collagen helps protect our skin barrier against environmental stressors like pollution, sun damage, etc. When our collagen level is high, our skin is automatically healthy, and the skin barrier is stronger. This simply means less redness and irritation and faster healing of the skin in case of breakouts.

How to boost collagen production?

Collagen is available in creams, serums, supplements, and even drinks. But with so many options, it’s easy to feel overwhelmed. It is often pointed out that collagen molecules are too large to penetrate the skin’s surface, raising questions about the effectiveness of topical products. So what’s the deal here?

Collagen molecules are indeed large, making it difficult for them to penetrate the deeper layers of the skin where they’re needed most. Most topical collagen products sit on the skin’s surface, acting as moisturizers rather than true collagen boosters.

If you’re expecting your topical collagen cream to magically boost your skin’s collagen levels, I hate to break it to you—it doesn’t work that way. While collagen creams can hydrate and temporarily plump your skin, the collagen molecules in these products are too large to penetrate deeply into your skin. Instead, look for products with ingredients that support collagen production, like retinoids, peptides, or vitamin C. These work beneath the surface to help your skin produce its own collagen naturally.

Bottom line: while collagen itself cannot penetrate the skin, you can include ingredients in your skincare routine that increase collagen synthesis.

Topical vs. oral

Collagen, when taken orally, appears to have more significant benefits for collagen synthesis—especially in the form of collagen peptides or hydrolyzed collagen. These forms are broken down into smaller molecules, making them easier for the body to absorb and utilize. While some topical creams may contain hydrolyzed collagen, external application is still not as effective as consuming collagen through supplements or drinks. That said, before adding any collagen supplementation to your routine, it’s important to consult your physician to ensure it’s safe and suitable for your individual needs.

Final verdict

while the market is flooded with collagen-boosting products promising overnight miracles, many of these claims are more marketing hype than science-backed facts. The truth is that topical collagen absorption isn’t really a thing. But don’t worry, there are real heroes you can count on and incorporate in your skincare routine. Ingredients like vitamin C, retinoids, and peptide serums can naturally boost your skin’s collagen production. And don’t forget to load up on protein-rich foods to support collagen from within.

If you haven’t already, it’s time to introduce tretinoin into your skincare routine—it’s a game-changer for preventing collagen loss. As for oral collagen in the form of hydrolyzed collagen? It actually holds some ground, so feel free to add supplements or drinks to your regimen.

But when it comes to topical products, don’t just grab anything labeled ‘collagen.’ Instead, invest in formulas packed with peptides and other collagen-boosting actives like Vitamin C, peptides, and matrixyl. Otherwise, you might just end up with another fancy moisturizer. I personally like Dr Dennis Gross and The Ordinary copper peptide serum, along with my retinol, and this duo has been working so well for me. Following are my favorites.

FAQs

Do collagen supplements actually work?

Yes, but with a catch! Collagen supplements, especially hydrolyzed collagen peptides, are broken down into smaller molecules that your body can absorb. Studies suggest they may improve skin elasticity, hydration, and overall appearance over time. However, results vary, and consistency is key. Always consult your doctor before starting any supplement.

What’s the best way to boost collagen naturally?

The best approach is a combination of diet, lifestyle, and skincare:

• Diet: Eat protein-rich foods like bone broth, fish, and eggs, and include vitamin C-rich fruits (like oranges and strawberries) to support collagen synthesis.
• Lifestyle: Avoid smoking, limit sun exposure, and stay hydrated.
• Skincare: Use products with retinoids, vitamin C, or peptides to stimulate collagen production and protect your skin from damage.
