What is cancer? All the cells in our body, and in all multicellular organisms, are regulated in multiple ways to make it possible for the organism to function as a whole. Cell division is a very tightly regulated process, and many genes participate in its regulation. As we age, our cells divide again and again and, despite all the corrective mechanisms that ensure that there are no major “typing errors” when DNA duplicates, errors occur. These are called mutations. We can see that our skin cells have mutated in the sun spots that accumulate as we age. This means that the DNA mutations have affected, in one way or another,…

For other brands, the most relevant questions are “does it feel good, does it smell good”? But at Skin Actives Scientific we are looking for activity, not just for a pleasant feel that will appeal to your senses. For SAS products the main question is: “does it work?” So far, for every product we make, the answer has been “yes”. Our products are based on good science and we make them very well. How long do they take to work? The time line is different for different products, because aside from products that aim at increasing skin moisture (like ELS, instant comfort), the others may only show benefits when the…

The evidence published in scientific journal shows that, as many other chemicals, vitamins, etc., copper (and copper complexed in a peptide) can be beneficial at very low concentrations and detrimental at higher concentrations. This makes sense: a significant portion of the toxicity of copper comes from its ability to accept and donate single electrons as it changes oxidation state, producing reactive free radical. This same property of copper is used by come enzymes that are crucial to cell metabolism, like superoxide dismutase, tyrosinase and more, and this is why copper is an essential micronutrient. Enzymes use copper in a carefully orchestrated reaction, free copper is another matter. With its capacity…
