  • What causes wrinkles?

  • A witch's potion.

  • No.

  • Our skin consists of two important proteins called collagen and elastin.

  • Collagen keeps our skin firm and tight.

  • While elastin gives our skin flexibility and elasticity.

  • It allows our skin to stretch, twist and contract.

  • Just like an elastic rubber band, right?

  • Absolutely.

  • But as we age, our skin produces less collagen and elastin.

  • Hence, our skin no longer remains firm.

  • It begins to lose elasticity.

  • As a result, our skin droops, thus causing wrinkles.

  • Moreover, there are some factors that can cause early wrinkling.

  • One of them is UV radiation of the sun.

  • Long term exposure to UV radiation can cause collagen and elastin to break down faster than normal.

  • Thus causing wrinkles in early age.

  • Besides this, smoking and poor nutrition may also contribute to early wrinkling.
