摘要
Chronic over-exposure to UV radiation leads to the damage of skin tissue. The aim of this study was to investigate the effects of collagen peptide (CP) and antioxidant (astaxanthin, vitamin C (Vc), and vitamin E (Ve)) combinations on skin photoaging. Forty male UV-induced BALB/c mice were randomized and fed saline or CP and antioxidants for 7 weeks using gavage feeding. The results showed that oral administration of CP, CP combined with Vc and Ve (VCE) or Haematococcus pluvialis extract (HPE) significantly (P < 0.05) reduced a* of mouse skin and increased the content of Hyp and type I collagen to varying degrees, thereby improving skin integrity. Furthermore, the combination of CP, HPE, and VCE showed increased upregulation of antioxidant enzyme expression, reduced serum ROS, and decreased inhibition of metalloproteinase expression compared to the other treatment groups. Thus, this combination showed better effects in inhibiting collagen degradation and maintaining the redox balance. The Nrf2/ARE and TGF-β/Smad transcription systems are likely involved in these effects. Therefore, the results suggest that a diet containing CP, astaxanthin, and vitamins might be recommended to improve skin health and appearance.
