Pigmentation on the face and the neck is because of various reasons and the one among them is the regular tan, which is caused because of UV exposure. It need not be in the sun, but it can be because if artificial lights like LED lamps, computer screens, cooking not he kitchen. It can emit a lot of infrared radiation and that can augment the UV damage and hence it is very important to know that the pigmentation can happen not only when you are outside in the sun, but also when you are indoors as well. Second common cause in India is because of acanthosis nigricans, where the skin becomes little bit dark as well as thick.it involves usually not uniformly in the face, about also the sides of the forehead, around the eyes around the mouth, neck. Wherever there are body folds, it involves around the eyes, around the mouth, around the lips. It can also involve the underarms, the groins, the neck, the knuckles and other body folds. So this type of pigmentation is not simple pigmentation and it increases with body fat, with sedentary lifestyle and when people have underlying hormonal issues, like thyroid, diabetes, PCOD. This type of pigmentation can be definitely reduced by on using a regular sunscreen and second to use a depigmenting creams. there are lot of depigmenting creams which contain glycolic, argic, kojic. there are other ingredients like Vitamin c which are used to lighten the skin. Depending on that depending on the intensity of the pigmentation, we treat the pigmentation with peels, with glycolic peels, fruit acid peels, or we go ahead with TCA peels or other phenolic peels and other peels like gesners peels. In addition to this we switch on to lasers like Q switched lasers are a very good modality of treatment, which not only treats the superficial but also the deeper components.
