Among the recent innovative cosmetic surgery practices today are the laser removal of birthmarks, scars and tattoos. If you have an unpleasant or unattractive birthmark, a disfiguring scar or a tattoo that you don't want anymore, then laser removal is your solution.

In comparison to traditional previous procedures which were invasive and painful, laser removal of unsightly marks is swift, convenient and pain-free. In the past, a tattoo would be removed by dermabrasion (sanding it off) or by surgical excision, with the possible necessity of a skin graft. Tattoo wearers are now thankful for the advent of laser therapy which is more commonly used.

Laser therapy uses highly concentrated laser light vibrations to disintegrate the birthmark or tattoo. The laser design hits only the targeted area for treatment using frequencies that will save the nearby tissue. After the birthmark pigment or tattoo is fragmented by the laser, the disintegrated pieces are removed from the skin by its natural immune system.

This procedure is ideal for areas with good blood circulation. The blood speeds up the removal of the fragments. Hands and feet have less circulation, which make these parts harder to treat.

Laser removal of birthmarks or tattoos should be done by a board certified cosmetic surgeon with sufficient experience. Upon consultation, your skin will be evaluated prior to the operation. The surgeon will decide which area to be treated and the number of treatments to be done plus the rate of success you can expect. The easiest tattoos to be removed are the black ones; colored tattoos need more treatment sessions before being completely removed.

Treatment and recovery

The pulses of laser light would feel like tiny bands of rubber snapping against your skin. Most people would not find this painful, but, the threshold for pain is unique to everyone. Doctors usually let the patients apply anti-inflammatory and anesthetic creams prior to the procedure. If you are the type to feel pain easily, your doctor might prescribe a local anesthetic.

The number of sessions would vary depending on the tattoo or birthmark, from one to ten sessions every four to eight weeks. The succeeding sessions would pierce deeper, resulting in the tattoo or birthmark lightening progressively after each session.

Recovery

After the procedure, your doctor would bandage your skin and apply anti-bacterial ointment, with instructions to raise the treated area to avoid swelling. You will also be instructed to keep the treated area away from the sun because it is going to be extra receptive to UV rays. A slight sunburn feeling and localized redness are reported by some people after the procedure. Sometimes a scab would develop in the area but this will subside after two weeks. Anti-inflammatories reduce any pain but you must consult with your doctor and not self-medicate.

There are rare instances of any side effects to laser therapy. There could be pigment loss for dark-skinned people and this should be reported to the doctor.

Introduction

Got a mystery to solve?

Somebody’s been making off with your stuff, and you don’t have a clue who it is, do you?

Here’s your chance to catch them in the act.

You Will Need

• A laser pointer
• Some Duct tape
• A few small mirrors
• An L.M.741 microchip
• A 220-ohm resistor
• A photocell
• An inexpensive digital camera
• An extra small screwdriver
• A wire coat hanger
• Some thin, insulated wire
• A printed circuit board
• A 9 volt battery
• A 9 volt battery clip
• Soldering equipment
• A pair of wire cutters
• A soap caddy with drainage holes
• A voltage relay

Step 1: Build the circuit

Build the circuit. Center the microchip on the circuit board. Pop in the voltage regulator. Connect the battery clip leads to the regulator. Run 2 more leads out from the regulator. Pop in the resistor and the photo cell. Link the chip to the photo cell. Pop in the relay. Link the chip to it as well. Link the other side of the relay to “power.”

Step 2: Disassemble camera

Disassemble the digital camera so you can access the board connected to the camera’s trigger button.

You may have to remove the camera’s board to get a good solder point on the terminal.

Step 3: Solder wires to terminals

Look for the two tiny terminals that lead to the trigger button. Solder wires to each of these terminals and feed them through the trigger button hole.

Step 4: Reassemble the camera

Reassemble the camera. If you can’t get it back together easily, use duct tape to keep it closed. Just don’t tape over the lens.

Step 5: Position circuit inside soap caddy

Position the circuit inside the soap caddy so the photocell is exposed behind one of the holes.

Step 6: Connect battery to circuit

Connect the battery to the circuit, and use tape to secure the whole assemblage inside the box.

Step 7: Attach wires to voltage relay

Slip the two wires coming from the camera through another hole, and attach them to either side of the voltage relay.

Step 8: Cut & tape coat hangers

Cut the coat hanger into several pieces. Tape one piece to the laser pointer and the others to the back of the mirrors.

Step 9: Place camera

Place the camera in an inconspicuous location with the lens pointing at the object you want to protect and secure it in place.

Step 10: Position laser pointer

Position the laser pointer in another inconspicuous place and secure it too.

Step 11: Place mirrors

Place the mirrors to create a perimeter around the object you’re protecting, adjusting them until the laser hits the photocell.

Step 12: Test the system

Now break the beam to test the system…

And get ready to confront the perpetrator with your irrefutable evidence.

FACT

The term LASER is really an acronym for Light Amplification by Stimulated Emission of Radiation.
