How is IPL used to treat benign vascular lesions?
Aging, sun exposure and other factors can cause the appearance of broken capillaries and blood vessels on the face known as telangiectasias, which appear as spider veins. Sometimes broken capillaries can cause a diffused redness in the skin, called erythema, a source of social embarrassment for many people. Rosacea is a common skin condition that is characterized by diffused erythema. All of these conditions respond well to IPL. 
For unsightly veins on the legs, both IPL and Nd:YAG laser technologies together are capable of addressing these lesions. During treatment, Intense Pulsed Light or laser light is absorbed by the blood in these small veins, heating and destroying the vessels. Over time the destroyed veins are reabsorbed and disappear.

What are IPL Skin Treatments using Photo rejuvenation? 
The term "Photorejuvenation" refers to the non-ablative, non-invasive treatment of red and brown pigment that leaves a smooth skin texture and even complexion, yielding a more youthful appearance.
IPL Skin Treatments are a safe, effective and popular way to improve the signs of aging from the face, neck, chest, arms and hands. This in-office procedure is performed by a physician or trained medical staff member and typically requires four to six sessions of about 20 minutes each, performed at approximately three-week intervals. 

How many treatments will I need ?
On average a patient will require 6~8 treatments to achieve the maximal result. This is because target tissue such as capillaries and melanin are at different depths whilst hair grows in cycles. To be treated hair must be in its active phase rather than dormant. Different parts of the body grow hair at different rates. It is essential that patients return at the recommended times to achieve the optimal result. Occasionally some people will need more treatments. These include those with hormonal imbalances, such as polycystic ovarian syndrome, and require those with darker skin where lower energy levels must be used to protect the skin. Some patients will a maintenance treatment a few times a year. Essentially, once target tissue is treated it is gone forever. Any re-occurrence is new hair or blood vessels that were not present at the time of treatment. Blood vessels and pigmentation located in the deeper dermis cannot be treated as the risk of damaging the dermis outweighs the benefit of trying. For this reason some patients may find that unwanted blood vessels and pigmentation problems are improved but not completely resolved. Men wanting hair removal are special cases where a reduction in hair is possible but complete resolution impossible, due to their high testosterone levels stimulating hair growth.
