Eating More Vitamin C Directly Boosts Collagen and Skin Renewal, Study Finds
New research links vitamin C intake directly to healthier skin. Scientists found clear changes in skin structure and renewal. As a result, diet plays a bigger role than expected. Researchers from the University of Otago led the study. They focused on how skin reacts to vitamin C levels. The findings surprised even experts.
Blood Levels Shape Skin Health
The study shows skin vitamin C reflects blood levels closely. Therefore, what you eat matters greatly. Higher intake leads to higher skin levels.This response appeared stronger than in other organs. In addition, skin absorbed vitamin C across all layers. That pattern showed efficient delivery through the bloodstream.
Kiwifruit Trial Delivers Results
Researchers studied healthy adults in New Zealand and Germany. Participants ate two vitamin C-rich SunGold kiwifruit daily. This habit lasted eight weeks.Plasma vitamin C levels increased quickly. As a result, skin vitamin C also rose. Scientists saw thicker skin and better renewal.
Collagen Production Gets a Boost
Thicker skin signals higher collagen production. Therefore, vitamin C supported stronger skin structure. Researchers also noted faster epidermal renewal.Advanced testing confirmed these changes. For example, ultrasound showed improved thickness and elasticity. Cell regeneration also increased.
Diet Works Better Than Creams
Many skincare products contain vitamin C. However, topical absorption remains limited. The skin struggles to absorb it through the outer barrier.Dietary vitamin C works differently. It reaches skin through blood circulation. Moreover, the skin prioritizes uptake naturally.SunGold kiwifruit was used due to high vitamin C. However, other fruits and vegetables work too. Citrus, berries, broccoli, and capsicum offer similar benefits.Experts suggest about 250 mg vitamin C daily. Since the body does not store it, regular intake matters. Therefore, eating fresh produce daily supports long-term skin health.
