On the other hand, hyperpigmentation is considered to be related to skin inflammation and ultraviolet irradiation, and various factors lead to the enhancement of melanocyte activity and the formation of hyperpigmentation. 2. Symptoms are different: Coffee spots are brown patches of skin with clear boundaries, and their shapes are not fixed, they may be round, oval or irregular, but the boundaries are clear and the surface is smooth. Early hyperpigmentation will have irregular patches or plaques of light brown and dark brown skin with unclear boundaries, and the color of the hyperpigmented area will be aggravated after sun exposure. 3. Different treatments: Coffee flaps generally do not need treatment, feel the impact of appearance is optional laser treatment, but there is a risk of recurrence. If the hyperpigmentation is mild, it will fade away by itself, while if the hyperpigmentation is more serious, it is necessary to use hydroquinone cream, Vitamin A cream or choose chemical peeling treatment as prescribed by the doctor.
