Yeast Essence Z20

Introduction

Introduction

Yeast Essence Z20 is extracted from zinc-enriched yeast by biological enzymolysis.In addition to containing a large number of skin-rejuvenating amino acids, peptides, nucleic acids and other biologically active substances, Z20 also contains the active zinc for skin metabolism. The chelated form of zinc reduces the skin irritation caused by zinc, which makes it good at anti-inflammatory and anti-acne.

Zinc is important and necessary to healthy skin.Zinc is extremely important to the proliferation of fibroblasts and the synthesis of collagen fiber. According to the studies, the serum level of zinc in patients suffering from psoriasis, seborrheic dermatitis and acne vulgaris were lower than the level of healthy objects.

Using patented raw materials and advanced biotechnology, refined with a series of patented technology of fermentation, enzymolysis and membrane separation, Z20 has a variety of skin-beneficial effects, such as anti-inflammatory, anti-acne and anti-aging.

 

 

Mechanism

Mechanism of functions

 

 

 

Efficacy

1. Z20 for skin oil-control (In 5% formula)

Face skin of 30 subjects was selected as the test area, the skin oil content of the forehead and cheek were tested by Skin Oil Tester (Sebumeter SM815, Germany CK Company).

Improvement of skin after 4 hourstests

 

During the test period of 4 hours, the skin oil content of the forehead and cheek were increasing, but the skin oil content of the 5% Z20 groups was lower than the blank groups, showing that Z20 was efficient in skin oil-control, and it was most efficient after 4 hours.

 

 

2. Z20 for skin oil-control (100% original Z20)

Face skin of 30 subjects was selected as the test area, the skin oil content of the forehead and cheek were tested by Skin Oil Tester (Sebumeter SM815, Germany CK Company).

Figure 2 Change rate of the skin oil content during the tests

 

 

Figure 2 shows that, during the test period of 4 hours, the change rate of skin oil content were increasing after using of the samples, but the change rate were lower than the control groups in hour 1, hour2 and hour 4, showing that the skin oil content of the sample groups was lower than the control groups.

Figure 3 Relative change rate of the skin oil content during the tests (*p<0.05)

 

Figure 3 shows that, during the test period of 4 hours, the relative change rate of the skin oil content were negative in hour 1, hour2 and hour 4, showing that the skin oil content of the sample groups was lower than the control groups, and there was significant difference (p<0.05) in hour 4, showing that Z20 was efficient in skin oil-control.
