Loss of firmness caused by photoageing
Our skin consists of different layers: the outer epidermis, the complex inner dermis, and the hypodermis. The skin‘s dermis contains the dermal matrix, which includes collagen, elastin, and hyaluronic acid that provide the skin with its structural framework and elasticity
As the skin ages, fibroblast cells that are responsible for the synthesis of collagen and elastin within the dermal matrix decrease in number and can become dysfunctional. As these collagen and elastin fibres degrade, the skin becomes thinner, drier, less elastic, and loses its youthful lustre.
What is photoageing?
Ultraviolet (UV) rays account for the majority of cosmetic skin conditions and are the main cause of premature skin ageing Photoageing can also be described as extrinsic ageing
