Inclusion criteria

The subject is a male or female of skin type I to IV between 25 and 75 years of age.
The subject has mild venous disease (CEAP Class C1) (CLINICAL SEVERITY ETIOLOGY OR CAUSE ANATOMY AND PATHOPHYSIOLOGY)
Reticular veins and telangiectasias on symmetrical bilateral lower extremities.
The subject is willing to follow study instructions and complete all required visits, as well as has agreed to and signed the written informed consent form.
The subject is healthy as judged by medical history and investigator's assessment of current health.
The subject is not suffering from any skin condition (infection, dermatosis, etc.) that in the opinion of the investigator may place them at risk.
