Daily consumption of two SunGold kiwifruit for 8 weeks increased skin vitamin C levels and improved skin density in patients with low baseline plasma ascorbate.
2
Whole-skin ascorbate concentrations rose significantly from 99 nmol/g to 150 nmol/g tissue after the dietary intervention.
3
Epidermal cell proliferation increased from 21 to 27 intensity units, indicating enhanced skin function due to increased vitamin C.
4
The study established a positive correlation between plasma and skin ascorbate levels, highlighting the epidermis's responsiveness to plasma ascorbate.
5
Researchers concluded that increasing dietary ascorbate intake could optimize skin function through enhanced collagen synthesis and cell proliferation.
