Many studies have shown that there are various factors in wrinkled skin. Aging is obvious, but over exposure to the sun, as well as consistent use of tanning beds is a major factor.
Everyone prefers the “tanned” look and studies show that in 2014, over 50% of people aged 18 to 25 had attempted tried indoor tanning. Around 25% of them did it on a regular basis. Strong data links the use of a tanning bed at a younger age with skin cancers
The way indoor tanning works is that it gives a high dose of ultra-violet (UV) rays, with the end result being that it makes the skin pigmentary process quicker. The beds transmit UVA and UVB energy. This is linked to what is called “photoaging” The UVB rays begin to stimulate the melanin pigments in cells. These then react within the  top layer of the skin (epidermis). The UVA rays, at the same time, makes the melanin darker which results in a tanned appearance
