Q-Switched Laser in Denizli: Tattoo Removal, Carbon Peel and Hair Lightening

Q-Switched Laser

Short answer

A Q-switched laser delivers its energy in very short, powerful pulses lasting nanoseconds. Each pulse is so brief that the targeted pigment shatters before heat spreads to nearby tissue. In dermatology it is used for tattoo removal, some brown spots, carbon peels and lightening fine, pale hair. In Denizli, the Q-switched laser is used by Spec. Dr. Tuba Çelebi Kayhan.

At our clinic we use Helios II, a Q-switched Nd:YAG laser. The device also has a fractional handpiece, which spreads the energy across the skin in tiny dots and is used for skin rejuvenation. With the same device we can treat tattoos and pigment spots, lighten fine hair and carry out carbon peels.

How Is a Q-Switched Laser Different from Other Lasers?

Most lasers deliver their energy over longer periods and work by heating the tissue. A Q-switched laser concentrates its energy into pulses lasting a billionth of a second. Under this sudden burst of energy, the pigment particle breaks into small fragments before it has time to heat up.

Because the heat does not spread, treatment can be selective, aimed only at the target tissue. The fragmented ink and pigment are then gradually cleared away by the body's scavenger cells.

What Is a Q-Switched Laser Used For?

  • Removing tattoos and permanent make-up
  • Sun spots, age spots, freckles and light brown café-au-lait macules
  • Deep-lying birthmarks such as naevus of Ota, naevus of Ito and Mongolian spots
  • Carbon peels for oily skin, acne and enlarged pores
  • Lightening fine, pale hair
  • Skin rejuvenation with the fractional handpiece
  • Supporting the treatment of nail fungus

How Does Laser Tattoo Removal Work?

The laser light is absorbed by the ink that gives the tattoo its colour, and the ink particles are broken into smaller pieces. Over the following weeks these fragments are carried away by the lymphatic system. Because this clearance takes time, we wait 6 to 8 weeks between sessions; the tattoo fades a little more with each one.

When needed, we give a local anaesthetic to the area before treatment. Afterwards there may be swelling, redness and a burning feeling; a thin crust or small blisters can also appear. During this time you need to keep the area clean, leave the crusts alone and protect the skin from the sun.

Which Tattoos Are Harder to Remove?

Black and dark tattoos respond better to the laser. Purple, green and yellow are the hardest colours to remove. Tattoos on the hands, feet and lower legs can also be more resistant to treatment.

In professional tattoos the ink sits deeper in the skin but at levels close to one another, so removal tends to progress more evenly. Where the ink is very dense or has been layered, more sessions are needed.

How Is a Carbon Peel Done?

A carbon peel is a skin rejuvenation treatment carried out with the Q-switched Nd:YAG laser. The face is first cleansed and a thin carbon solution is applied to the skin. After the solution has been left on for about 10 minutes, the laser pulses begin; the laser shatters the carbon particles and lifts them away from the skin.

A carbon peel can address several problems in the same session:

  • Active acne and acne scars
  • Uneven skin tone and pigment spots
  • Excess oiliness
  • Enlarged pores
  • Loss of elasticity and fine wrinkles

Depending on your needs, we plan 5 to 10 sessions 7 to 14 days apart. A brighter look may be noticed after the first session, and the effect becomes clearer as the sessions continue. You do not need to take time off from daily life. We can also carry out this treatment in summer; during this period you need to use sunscreen every day. Peeling the skin with acids is a separate treatment, known as a chemical peel.

Who Is Laser Hair Lightening Suitable For?

Hair lightening is an option for hairs too fine and pale for a conventional hair removal laser to treat. It is used on the soft, downy hair of the face and arms and can be done in any season. For dark, coarse hair, laser hair removal is the more suitable method.

Straight after treatment the hairs turn white, and they shed within a week or two. Depending on the hair type, regrowth takes 1 to 3 months. The hairs that grow back do not become thicker or darker; with repeated treatments the hair may become sparser.

How Is Pigmentation Treatment with a Q-Switched Laser Planned?

The first step in laser treatment for pigmentation is to identify the type of spot at an examination. Sharply defined sun spots, called lentigines, can fade in one or a few sessions. Freckles can also be treated, but they tend to darken again with sun exposure.

Melasma, on the other hand, is a type of pigmentation linked to hormones, genetic tendency and sun, and it tends to come back. For melasma we do not use the laser on its own but in low-energy sessions combined with sun protection and topical creams; in this case 6 to 8 sessions 1 to 2 weeks apart may be planned. You can find all the options for each type of pigmentation under pigmentation treatment.

What Should I Be Careful About After Q-Switched Laser Treatment?

After pigment and hair lightening treatments there is mild redness, which usually settles within a few hours; some spots peel lightly. You need to protect the treated area from the sun for at least a few weeks. On sun-exposed skin, or with treatment at the wrong energy, temporary lightening or darkening of the skin can develop; this is why we set the energy to suit your skin type.

Frequently asked questions

Can a laser remove a tattoo completely?
Black and dark tattoos can be expected to fade to a large extent. With coloured, very densely inked tattoos, or tattoos on the hands and feet, a faint shadow may remain; we discuss the likely result after seeing the tattoo.
Can permanent make-up and eyebrow tattoos be removed with a laser?
Yes, but the skin-tone and white pigments used in permanent make-up can darken under the laser. For this reason we first test a small area.
Can I go back to work after a carbon peel?
Yes. The skin may look slightly pink after a carbon peel, but you can return to your daily work the same day. Using sunscreen is all you need to do.
Can laser hair lightening replace laser hair removal?
No. Hair lightening is for fine, pale hairs that a hair removal laser cannot treat. For dark, coarse hair, laser hair removal is the more suitable method.
Does Q-switched laser treatment hurt?
With pigment and hair lightening treatments you feel small pinpricks. The sensation is stronger during tattoo removal, so when needed we give a local anaesthetic before treatment.
How many sessions does tattoo removal take in Denizli?
At our clinic we plan tattoo removal sessions 6 to 8 weeks apart, and 4 to 10 sessions are usually needed. The number depends on the colour of the tattoo, the density of the ink and its location.
