The skin ages due to a lack of production of collagen and other proteins that make up its structure, such as elastin and hyaluronic acid. Over the years, some of the cells in our body stop performing their function properly and this causes visible signs of ageing. To make it clearer:
There are also factors that promote premature ageing. For example, smoking accelerates collagen loss by 2 times and sunbathing by 1.7 times. However, there is evidence that certain procedures or substances activate collagen formation, stop collagen destruction or both. In this way, we can halt or even reverse the ageing process.
