Laser Tattoo Removal—A Laser Dermatologist Explains the Little-Known Facts

Some Patient Tattoos Seen at BHSkin Dermatology

Laser light can pass through adjacent tissues to reach retained pigment particles inside cells within the tattooed area. This selectivity allows the laser to remove tattoo ink while keeping the surrounding skin mostly unaffected.

Immune cells can then act on the smaller or chemically altered pigment particles. The ink fragments are later cleared through the lymphatic system and lymph nodes.

Which Laser Technology Is Most Effective for Getting Rid of Tattoos?

Green and blue are among the toughest tattoo colors to remove with laser treatment. At our Encino clinic, we use a state-of-the-art device called the “Qanta QS Plus-C.” This device has a ruby laser that emits deep-red light (694 nm) that can address stubborn green and blue pigments in multicolored tattoos.For decades, the Q-switched Nd:YAG laser has been the gold-standard device for tattoo removal. The rapid bursts of laser energy enable fragmentation of ink particles while minimizing heat buildup in the surrounding tissue.

Q-switched Nd:YAG lasers commonly use two wavelengths for tattoo removal—532 nm and 1,064 nm. The 532-nm wavelength falls within the green light spectrum. The 1,064-nm wavelength is in the invisible, near-infrared range.

The 532-nm laser is commonly used for warm-colored pigments, specifically red, orange, and yellow. But it’s also absorbed more readily by melanin. In people with skin of color, melanin absorption at 532 nm can interfere with tattoo removal and increase the likelihood of scarring and skin discoloration. Your dermatologist can reduce these risks by adjusting the laser settings, cooling the target area during the procedure, or switching to a different wavelength altogether.

The 1,064-nm wavelength is particularly effective for black and dark blue pigments, which are among the easier tattoo colors to remove. Since the natural skin pigment melanin absorbs less of this kind of light, your laser dermatologist may recommend it if you have a dark skin tone. 

Can You Use CO2 and Erbium Lasers for Tattoo Removal?

Laser skin resurfacing, which uses CO2 (10,600 nm, far infrared) or erbium (2,940 nm, mid-infrared) lasers, may be used to remove white, tan, brown, or rust-colored inks that often contain iron or titanium oxides. Pigments with these metallic components may darken when treated with Q-switched devices. Laser resurfacing removes the layers of skin containing the pigment, gradually eliminating the tattoo along with the treated tissue.

However, laser resurfacing is more likely than Q-switched 1,064-nm treatment to cause pigmentation changes or scarring, particularly in people with skin of color. Talk to your dermatologist to find out whether this approach is right for you.

What Should You Expect When You Make an Appointment for a Laser Tattoo Removal Procedure?

Using laser treatment to remove tattoos requires careful planning and execution. What you do at every stage can impact your results. Let’s take a look at the essentials.

Before Your Procedure

Your dermatologist will make a complete evaluation to find out if laser tattoo removal treatment is appropriate for you. Factors like poor immunity, malnutrition, clotting problems, and uncontrolled blood sugar issues can make it harder for your skin to heal within a reasonable amount of time. Conditions affecting the tattooed area, such as infection, active inflammation, or skin cancer, can also make laser removal unsuitable.

Lasered ink particles can reach your bloodstream and circulate throughout your body. I’d advise a different tattoo removal method if you’re carrying a child or breastfeeding, or if you have a history of severe allergic reactions.

Various factors determine how many laser removal sessions you’ll need. Your laser dermatologist may use the Kirby-Desai scoring system to estimate the number based on the following factors:

• Skin type — Your skin type can affect both the laser settings and the number of sessions you may require. Darker skin types often need more conservative laser settings, potentially increasing the number of sessions.
• Tattoo location — Tattoos on the hands, feet, and lower legs tend to clear more slowly than those on the head, neck, and chest, being farther from the body’s lymph nodes.
• Tattoo ink color — Some pigments respond more readily to laser energy than others. Unknown ingredients in some tattoo inks can make their response less predictable.
• Amount of ink — Tattoos with more densely packed or deeply deposited ink generally need more sessions to clear.
• Scarring and other tissue changes — Scars or other texture irregularities, such as lumps and thickened skin, can make ink more difficult to remove, especially in older tattoos.
• Layering of tattoos — Cover-ups or tattoos with multiple layers of ink typically require more sessions than tattoos with a single layer.

The number may be adjusted as your treatment progresses based on how your skin responds. The goal is to achieve the desired result using the fewest sessions necessary.

Sun protection before laser treatment is important. Tanning increases melanin, which can absorb laser energy and make you more prone to burns or pigmentation changes after the procedure. However, the target area must be free of sunscreen, cosmetics, and other skin-applied products right before your appointment, as they may interfere with the laser’s ability to reach the ink particles.

Your laser specialist may recommend a spot test, depending on your tattoo’s characteristics and your risk of developing side effects. Laser testing is performed in a small, inconspicuous area to assess how your skin and tattoo respond before proceeding with the full treatment.

Depending on your medical history, your laser provider may recommend taking an oral antihistamine or steroid before your appointment to minimize the risk of allergic reactions. Blood thinners, cigarettes, and alcohol may interfere with skin healing and should be avoided before your session.

During Your Procedure

Before settling into the treatment chair, you’ll be asked to change into a clinic gown and put on protective eyewear. Your specialist will cleanse the target site and help you get into a comfortable position.

The laser device has a built-in cooling system to minimize discomfort during the procedure. If you’re particularly sensitive to pain, your dermatologist may also provide numbing medication at the start of your session.

Your specialist will apply laser pulses to the treatment area. You may feel quick snaps as the device delivers each pulse.

A laser tattoo removal session may take an hour or more, depending on the size of your tattoo. Afterward, your dermatologist will clean the treated skin, cover it with a dressing, and give you aftercare and follow-up instructions before you go home.

After Your Procedure

Generally, aftercare instructions may include changing the dressing starting around 24 hours after your session and cleansing and moisturizing the treated area twice daily. Sun protection reduces the risk of pigmentation changes during healing.

You may use ice compresses for the first 24–72 hours to soothe inflammation, then switch to warm compresses to encourage circulation and speed up healing. Your dermatologist may recommend over-the-counter pain relievers for discomfort. They may also advise you to apply a steroid cream for a week to reduce inflammation.

Timeline of Skin Changes After a Laser Tattoo Removal Treatment: What’s Normal, and What’s Not?

You may notice a temporary whitening response immediately after laser removal treatment of a tattoo. This change occurs when rapid heating of the pigment causes tiny gas bubbles to form around the ink particles. The whitening usually fades within a few hours, followed by mild redness, swelling, weeping, and burning pain, which are normal skin reactions.

Pinpoint bleeding may occur when laser treatment reaches blood vessels close to the skin surface. Bruises may develop in areas with thinner skin and a richer network of superficial blood vessels, for which you may take arnica or bromelain supplements.

All these effects usually resolve within a week. However, healing processes continue beneath the surface long after your session. Treatments are often spaced 4–8 weeks apart to allow your skin to recover fully between procedures and to achieve the best results.

Abnormal changes may include infection, profuse bleeding, severe bruising, significant pain, redness, or swelling, or a serious allergic reaction. Improper laser technique or inadequate provider experience can increase the risk of these complications. Seek medical attention right away if you notice any of these signs.

As mentioned, some pigments may darken with Q-switch lasers, which may be avoided by spot testing or choosing an alternative approach, such as laser resurfacing or chemical peel treatment. Scarring may be minimized by using the appropriate laser settings and technique.

Inflammation-related hyperpigmentation may be treated with a skin-lightening agent, such as hydroquinone. Hypopigmentation may be addressed with UV phototherapy, which stimulates melanin production.

Incomplete ink clearance can leave an unsatisfactory appearance and, in some cases, cause lumps months to years after the procedure. Steroid injections in the affected area may help shrink these lumps, but good preparation, technique, and aftercare can improve the chances of complete removal and help avoid complications.

On a related note, besides potentially causing unwanted skin reactions, lasers can damage your eyes. That’s why protective eyewear is essential during the procedure.

Laser Tattoo Removal: A Complex Treatment That Requires a Skilled Hand

Getting rid of unwanted ink can stir up a lot of feelings, but it shouldn’t leave you with emotional, much less physical, scars. Laser tattoo removal is highly effective and generally safe, but medical expertise is essential to determine whether it’s right for you and to ensure you get your desired outcome.
