What is a cosmetic laser?  How does it work and where is it used?

A cosmetic laser is a device that uses intense light to affect various layers of the skin. One of its applications is the removal of tattoos or unwanted hair. Another is the treatment of varicose veins, which appear as blue or purple streaks on the legs.

How does a cosmetic laser work to remove tattoos or hair?

A tattoo is created by injecting dye into the dermis, the second layer of skin. A cosmetic laser emits pulses of light that penetrate the skin and break down the dye into smaller particles. These particles are then removed by the body’s immune system. This process can take several weeks to months, depending on the size, color, and depth of the tattoo. Multiple sessions are usually required to achieve the desired result.

Hair grows from follicles, small sacs under the skin. A cosmetic laser emits pulses of light that penetrate the skin and heat up the follicles. This causes damage to the follicles and stops hair growth. This process requires repeated sessions to achieve lasting hair removal.

How does a cosmetic laser work to treat varicose veins?

Varicose veins are caused by weakness or damage to valves that regulate blood flow in veins.

This leads to blood pooling in veins, causing them to swell and change color. A cosmetic laser emits pulses of light that penetrate the skin and heat up vein walls. This causes veins to collapse and close their lumen. This improves blood circulation and reduces vein visibility.

What are the benefits and risks of a cosmetic laser?

A cosmetic laser is a non-invasive method that can offer permanent or long-term solutions for some aesthetic problems. It can improve self-confidence and satisfaction with one’s body. A cosmetic laser is also relatively fast and precise.

On the other hand, a cosmetic laser can also have undesirable effects such as pain, swelling, redness, bruising, infection, scarring, hyperpigmentation or hypopigmentation of the skin. Some of these effects are temporary and disappear after some time, others may be permanent or require further treatment. A cosmetic laser may also not be suitable for everyone, such as people with dark skin, sensitive skin, active infections or certain diseases.

Therefore, it is important to consult with a qualified professional before undergoing any procedure with a cosmetic laser. The specialist should assess your expectations, health status, possible complications and alternatives. The specialist should also provide you with detailed information about the procedure, costs and aftercare.
