There loss of skin density is an integral part of natural aging. It manifests itself as a reduction in the thickness, firmness, and elasticity of the skin. This phenomenon is mainly due to:

• Decline in production of  collagen and elastin : These proteins provide the structure and elasticity of the skin. Their reduction leads to sagging skin and a loss of volume.
• Atrophy of subcutaneous adipose tissue : This thins the skin and makes it less plump.
• Slowing down of cell renewal : With age, the skin regenerates more slowly, which contributes to skin thinning.

Each season presents different challenges to the skin . While summer mainly requires care against the effects of UV rays and sweat, fall requires a routine focused on protection against dehydration and climatic aggressions. The products used in summer may not be enough to provide the skin with the nutrients and protection it needs during this season. Adopting a skincare routine adapted to fall helps prevent skin problems and strengthen the skin barrier.
