The Truth About Collagen Supplements: Can They Improve Your Skin?

Collagen is one of the most important proteins in your body—it keeps skin firm, smooth, and youthful. As we age, collagen production naturally declines, leading to fine lines, wrinkles, and sagging. Many people turn to collagen supplements, but do they really work? At MDCS Dermatology, Lauren Penzi, MD shares insights into the science and effectiveness of collagen supplementation for skin health.

What Is Collagen?

Collagen is a structural protein found in the skin, hair, nails, joints, and bones. In the skin, it acts like scaffolding—providing support and elasticity. After age 25, collagen production slows, and environmental stressors like sun exposure and smoking accelerate its breakdown.

How Do Collagen Supplements Work?

Most collagen supplements are hydrolyzed into peptides, making them easier to absorb in the digestive system. These peptides may signal your body to increase natural collagen production and help maintain skin elasticity and hydration.

What the Research Says

• Skin Elasticity & Hydration: Some studies show oral collagen supplements improve skin elasticity and moisture retention after consistent use for 8–12 weeks.
  
  
• Wrinkle Reduction: Evidence suggests that collagen peptides may help reduce fine lines by supporting dermal structure.
  
  
• Overall Skin Health: Benefits may be modest and vary from person to person. Collagen works best when combined with a healthy lifestyle and proper skincare.
  
  

Other Ways to Boost Collagen

While supplements can help, Dr. Penzi emphasizes that lifestyle factors play a major role in collagen health:

• Wear Sunscreen Daily: UV rays accelerate collagen breakdown.
  
  
• Maintain a Balanced Diet: Protein-rich foods, vitamin C, and antioxidants support collagen formation.
  
  
• Avoid Smoking & Excess Alcohol: Both deplete collagen and damage skin cells.
  
  
• Consider In-Office Treatments: Procedures like microneedling, PRP, and laser resurfacing stimulate natural collagen production for more noticeable results.
  
  

Should You Try Collagen Supplements?

Collagen supplements are generally safe for most people and may offer subtle improvements in skin texture and hydration. However, they aren’t a miracle cure. Dr. Penzi often recommends a personalized approach—combining supplements with proven dermatologic treatments for optimal skin rejuvenation.
