But you can bet everybody is facing problems like yours, in one way or another. The number of melanocytes is variably increased.50 There is an increase in endothelin-1 secreted by proliferating keratinocytes and an increase in endothelin B receptor expression in melanocytes of solar lentigine, suggesting an essential role for endothelin in the stimulation of epidermal pigmentation.51. 2011;33 Suppl 1:15-20. doi: 10.1159/000327044.

Vascular laser therapy can improve the telangiectatic component of this disease and depigmented agents will sometimes work on the hyperpigmentation. Use of fractional photothermolysis to treat poikiloderma of Civatte has also been described with promising results.
