A laser that selects wavelengths when redness and dark spots occur together.
Two wavelengths are chosen to suit the situation: one that works on shallow vessels and pigment, and one that reaches deeper vessels. The choice depends on whether the redness comes from surface capillaries or deeper vessels. Cooling is used alongside to reduce surface load and the risk of pigment settling.
It is done in three to five sessions at two to four week intervals. Redness and blemishes tidy up together over one to two months, because two wavelengths are selected and vessels and pigment can be addressed in the same session. The more marked the redness, the more sessions are needed.
