Changing of colors of the treated veins into red or brown should be expected. This will lasts for 6-8months. To help minimize the appearance of the discoloration, one should wear SPF when exposing the skin to sunlight. Application of Creams like Anti-Melasma Creams is also helpful for the hyperpigmentation.
One should also expect a feeling of hardness (cord-like) on the treated veins for the first three months. This is due to the hardening of tissues as a results of inflammation and fibrosis.
