The use of the Nd+ and Er+: YAG lasers is still under development for cutaneous resurfacing. Cooling the epidermis induces laser heating under invasive epidermal layer regime. Injuring the dermis can treat skin defects and improve its quality. Various therapeutic options have been utilized to treat aging signs. Laser resurfacing has proven effectiveness and popularity due to its shorter recovery time and high success rate. Non-invasive Nd: YAG laser and 2940nm Er: YAG laser pulses were employed to provide deep dermal laser heating and induce elastin and collagen regeneration. Two subjects of skin-tone 2 were laser treated in the present study. Photographs were taken before the treatment and after the last session. The 1064nm Nd: YAG and 2940nm lasers treatment results were followed up in treating fine and coarse wrinkles. The patients were given four sessions every other week. The laser energy was calculated at all interfaces between the layers of the skin in order to find out the exact laser fluence, and then the temperature rise at the targeted tissue. The 1064nm Nd: YAG laser was benefited more by younger subject while the 2940nm was better for older case.
