Are these reticular veins? Can they be treated? (Photo)

1-2 treatment session with foam sclerotherapy (1% Polidocanol)  will take them away effectively.

Thank you for the picture and for posting the question.These are small varicose veins and can be adequately treated with sclerotherapy. It is very likely that you have underlying venous insufficiency and a thorough study with Doppler ultrasound (Duplex) scan is necessary before such treatment is initiated. Read my ebook about venous insufficiency on the link below. Dr H Karamanoukian#RealSelf100 Member

The posted picture does show reticular veins and the gold standard of treatment is sclerotherapy.  You have many reticular veins and there may be an underlying reason for these such as saphenous vein valvular incompetence (reflux).  A venous ultrasound would show this.  See a vein specialist for a full venous evaluation before beginning sclerotherapy.
