Pico laser penetrates the skin to kill off the melanin that causes these spots. Conversely, chemical peels remove the top layer of the skin to stimulate the growth of a new layer of skin [1]. Pico laser and chemical peels treat sun spots, wrinkles and hyperpigmentation and improve skin texture/tones [2]. Pico laser, however, is preferred when removing tattoos.
If you are getting both, an interval of 2 weeks will be sufficient for the skin sensitivity to subside. Alternatively, do the chemical peel first, then followed by the pico-laser 2 weeks later. In this way, the effects of the pico-laser may be enhanced after the skin has been refreshed by the chemical peeling.
