We know that air pollution accelerates skin aging and leads to problems like hyper-pigmentation and inflammation. How? Cells all over the body are constantly adapting and responding to changes in their micro-environment: diet, bacterial flora and whole body metabolism. Then, they make the proteins that are required to do well in the new circumstances. It’s important to know that although our DNA codes for proteins, which proteins are made at each moment is a process tightly regulated. DNA–>RNA–> Proteins is a pathway that took many decades to elucidate. But how does the cell “decide” which DNA will be transcribed to RNA and which RNA will be translated into proteins? Figure: … Continue reading How does the skin sense pollution and how it reacts.
