Skin Aging… What you really need to know! (part 1)

What is skin aging?

As people age, their skin goes through changes. When they reach 40, they might notice certain changes in their skin like wrinkles, fine lines, age spots, and skin dryness. Skin gradually becomes thinner and loses its flexibility.

Types of aging:

Causes of aging can be divided in to two groups:

  • Intrinsic aging
  • Extrinsic aging

Intrinsic aging:  This type of aging is obvious with age. Usually, when people reach 40, their skin starts aging. Their skin loses fats and oils and becomes less flexible.

Symptoms of intrinsic aging:  There are certain signs of intrinsic aging of the skin, which appear with age:

  • Wrinkles
  • Fine lines
  • Loss of flexibility
  • Loss of thickness
  • Broken capillaries
  • Dullness
  • Dryness
  • Enlargement of pores
  • Less sweating
  • Lifelessness

Extrinsic aging:  Extrinsic aging is caused by the effect of environment on skin, such as UVA and UVB rays from the sun, cold weather, etc.

Symptoms of extrinsic aging:

  • Skin cancers
  • Dullness
  • Dark spots
  • Broken veins
  • Uneven complexion
  • Loss of skin firmness
  • Sun damage
  • Scars
  • Appearance of patches on skin

Why does skin age?

When people reach the age of 40, the skin’s ability to produce and replace new skin cells slows down. There is a layer under the skin called Dermis. This layer is very thick, and when people age, this layer starts becoming thin. Skin loses its ability to retain moisture. The glands that help improve skin elasticity become inactive, and the skin will lose its flexibility.
