Coffee spots on baby’s face are usually treated with physical therapy measures, such as Q-switched laser and intense pulsed light. Coffee spot is a kind of flat, uniform pigment hyperpigmentation disease, the cause of which is unknown and may be related to external light and genetic factors. 1. Q-switched laser: mainly through the principle of selective photothermal action, thus releasing huge energy to smash the melanin vesicles under the skin, thus treating coffee spots. 2. Intense pulsed light: belongs to photon therapy, which is also based on the principle of selective photothermal action, so that melanocytes absorb light energy and are crushed and discharged out of the body, so as to make discoloration lighten and disappear. Coffee spots may also be associated with a variety of systemic diseases, such as neurofibroma, Fanconi anemia and so on. Therefore, if your baby has coffee spots, you need to go to regular hospitals for examination in time, and standardize the scientific treatment after clear diagnosis, so as to avoid delaying the condition and causing adverse consequences.
