Study on the soothing effects of a novel efficacy complex on the skin of individuals with oily sensitivity
Objective:To comprehensively evaluate the soothing effects of a novel efficacy complex(referred to as"Penta-Ring essence")on the skin of individuals with oily sensitivity.Methods:An in vivo experimental approach with 34 healthy female subjects aged 18-60 years with oily skin from the Shanghai area was employed.The soothing effect of a long-term use of Penta-Ring essence on oily and sensitive skin was evaluated by a method of autologous before-and-after control.Results:A number of physiological indicators of the skin were significantly improved after the Penta-Ring essence was continuously used for 4 weeks,including 13.29%increase in the water content of the stratum corneum,11.72%decrease transepidermal water loss,1.91%decrease in skin temperature,21.21%decrease in skin sebum,7.70%decrease in skin E value,4.54%decrease in M value,5.84%decrease in skin chroma a* value,5.68%increase in skin chroma L* value and 58.16%decrease in the score after 2.5 min lactate irritation(all P<0.01).Conclusion:For oily and sensitive skin,the Penta-Ring essence can effectively increase skin hydration,reduce oil secretion and pigmentation,relieve inflammation,brighten skin tone with minimal irritation and significantly improve skin barrier function,which demonstrate its efficacy in skin soothing and repair.
