When it comes to youthful, glowing skin, collagen and hyaluronic acid (HA) are two of the most talked-about ingredients. But if you’ve ever wondered whether you need one over the other—or if combining them is the ultimate skincare secret—you’re not alone. Let’s break it down.

Understanding Collagen and Hyaluronic Acid

Collagen

Collagen is the structural protein that gives skin its firmness and elasticity. As we age, collagen production declines, leading to sagging, fine lines, and reduced skin resilience.

Hyaluronic Acid

Hyaluronic Acid, on the other hand, acts like a moisture magnet, drawing and retaining water in the skin. It helps keep skin plump, smooth, and well-hydrated.

Think of collagen as the framework of a mattress and HA as the cushioning that keeps it plush and bouncy. While they work differently, they complement each other perfectly.

Why You Need Both for Radiant Skin

• Collagen builds, HA hydrates: Collagen strengthens skin structure, but without hydration from HA, it can become brittle. HA ensures that the collagen matrix remains hydrated and functional.
• Better skin elasticity: Studies show that when combined, collagen and HA help improve skin elasticity and reduce wrinkle depth more effectively than when used separately (source: Journal of Cosmetic Dermatology).
• Aging defense duo: Loss of collagen leads to thinner skin, while declining HA levels make skin dry and less supple. Supporting both ensures optimal skin health.

How to Incorporate Collagen and HA Together

To get the best results, you can combine both ingredients in your skincare and supplements:

1. Topical Care

Look for serums or moisturizers that contain both hydrolyzed collagen and HA for surface-level hydration and plumping. A great option is the Neutrogena Hydro Boost Water Gel, which delivers a boost of HA while strengthening the skin barrier.

2. Ingestible Support

Since topical collagen doesn’t penetrate deeply, ingestible collagen is the best way to replenish lost stores. Pairing it with HA enhances absorption and effectiveness. A great choice is Vital Proteins Beauty Collagen, which has both collagen peptides with hyaluronic acid and Vitamin C from organic fruit powders.

Another option, which is more of a personal favorite for me, is Doki Doki’s LUNA Collagen. This collagen supplement combines marine collagen with hyaluronic acid, vitamin-rich foods, and prebiotics for deeper hydration and skin resilience.

3. Lifestyle & Diet

Eating HA-rich foods like bone broth and collagen-boosting foods like citrus and leafy greens can further support your skin from within. Staying hydrated and avoiding excessive sun exposure also help maintain both collagen and HA levels.

Final Thoughts 

Rather than choosing between collagen and HA, incorporating both into your routine—through skincare, supplements, and diet—can give you the best results. They work in harmony to keep your skin firm, hydrated, and glowing.
