How Antioxidants Protect Your Skin
Skin oxidative damage results from an imbalance between free radical generation and antioxidant defenses, of which unfavorable consequences include aging, increased risk of skin diseases, expedited loss of collagen and elastin, increased DNA damage, high skin sensitivity, and increased skin pigmentation.
Epigenetically regulated expression of the anti-oxidative stress genes generates gene products-antioxidant protein/enzymes, which can scavenge reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), the superoxide anion radical (O2-) and the hydroxyl radical (.OH). The ROS generally arises from chemical, physical, and metabolic challenges. The antioxidants usually include antioxidant enzymes such as SOD, catalase and glutathione peroxidase and non-enzymatic antioxidants such as vitamin E, C, A, flavonoids and carotenoid. Antioxidant plays the most important and essential basis in delaying skin aging through decreasing skin oxidant damage, stimulating collagen production and reducing loss of collagen and elastin.
Layer 1. skin epidermis: as initial barrier to oxidant assault, it provides endogenous antioxidant action. Layer 2. skin microbes: There are approximate one million bacteria per cm2 in human skin. As an integral part of the skin barrier, skin microbes can affect skin health by modulating host immune responses and the skin barrier function. Common bacteria on skin can secret antioxidant substance including RoxP to protect host skin from oxidative stress.
Your skin is dynamic which is generated by interaction with environment and controlled by epigenetics at gene and protein level. However, the skin antioxidant level will be decided eventually by the activity of enzyme and non-enzyme molecules on your skin . Thus, only a direct skin sample antioxidant test can truly identify the antioxidant ability of your skin and determine which skincare products are best to suit you.
Antioxidant skincare products can also provide exogenous antioxidant action and can be considered as layer 3 of the skin antioxidant system when these products are applied to skin. >90% skincare products claim to have antioxidant function but in fact it is not true, even if these products contain antioxidant ingredients. Thus, only a direct product antioxidant test can truly identify the antioxidant ability of your skincare products and determine which skincare products are truly effective and suited for you.
Truly Data Backed Skin Antioxidation Self Test
Skin antioxidant self-test identify both your basic skin antioxidant status and skin antioxidant level after applying skincare product/regimen in different skin area.
Using routine product regimen then tested with skin antioxidant self-test. Non-invasive skin samples were collected and tested according to skin antioxidant self-test instruction. The color signal intensity was correspondently measured by using spectrophotometer. Condition 1: basic skin status, no skincare products applied overnight. Condition 2: 2 hours after using skincare products. Eye outer corner: using product 13+14+16+20; Face: using product 13+16+26+32; Hand: using product 40.
Skin antioxidant self-test helps to identify actual effect of the best selected regimens after applied to skin.
Using product regimens selected by skincare product antioxidant self-test and then tested with skin antioxidant self-test kit. Non-invasive skin samples from eye outer corner were collected and tested according to skin antioxidant self-test instruction. The color signal intensity was correspondently measured by using spectrophotometer. Regimen 1: product 7+14; Regimen 2: Product 7+14+15+20. Condition 1: basic skin status, no skincare products applied overnight; Condition 2: after wash in the morning; Condition 3: 4 hours after using the regimen 1 or 2; Condition 4: 8 hours after using the regimen 1 or 2.
Skin antioxidant self-test helps to identify and compare actual effect of the best selected regimens after applied to skin in a time length.
Using product regimens selected by skincare product antioxidant self-test and then tested with skin antioxidant self-test kit. Non-invasive skin samples from eye outer corner were collected and tested according to skin antioxidant self-test instruction. The color signal intensity was correspondently measured by using spectrophotometer. Regimen 1: product 7+14; Regimen 2: Product 7+14+15+20. Condition 1: Regimen 1 or 2 was applied overnight; Condition 2: after wash in the morning; Condition 3: 4 hours after using the regimen 1 or 2 again; Condition 4: 8 hours after using the regimen 1 or 2 again.
Skincare product antioxidant self-test helps to identify true antioxidant level of various skincare product.
