Does Laser Tattoo Removal of Red Ink Damage Blood Vessels?

Does laser removal of red tattoos damage blood vessels?

I underwent laser treatment for a red tattoo, but the blisters from the red ink are larger than those from black ink, and there is also some subcutaneous edema.
Although I am fine a week later, I found online that the 532 nm wavelength might be absorbed by blood vessels and could potentially damage them.
The tattoo is located on my chest and is quite large.
I want to confirm whether the 532 nm wavelength could affect blood vessels or lymphatics, and if there are any associated risks.
During the laser treatment, I experienced significant pain and some discomfort in my heart, and I'm unsure if it was due to the pain or if a large number of red blood cells were being destroyed by the laser light.
Since I plan to continue treatment, I need to understand more about this.

Yes, but they are mostly microvessels, so there may be subcutaneous bleeding after the injection, which is harmless to health and will heal on its own.

More Info

Laser tattoo removal, particularly for red ink, can raise concerns about potential damage to blood vessels and surrounding tissues. The use of a specific wavelength, such as 532 nm, is indeed designed to target red pigments in tattoos. This wavelength is absorbed by hemoglobin, the protein in red blood cells, which can lead to the question of whether it poses a risk to blood vessels.

When laser energy is applied to a tattoo, it breaks down the ink particles into smaller fragments that can be absorbed and eliminated by the body. The 532 nm wavelength is effective for red inks, but it can also affect nearby blood vessels, particularly microvessels. This is why some patients experience localized swelling, blistering, or even bruising after treatment. However, these effects are typically temporary and resolve as the body heals. The skin and underlying tissues have a remarkable ability to recover, and any minor damage to blood vessels usually heals without long-term consequences.

In your case, the larger blisters and subcutaneous swelling you experienced could be due to a few factors, including the intensity of the laser treatment, the size of the tattoo, and your skin's response to the procedure. It’s not uncommon for red ink tattoos to react more intensely than black ink tattoos, as the different pigments can absorb laser energy differently. The pain you felt during the procedure and the subsequent discomfort may have been exacerbated by the sensitivity of the area being treated, especially since the chest is a sensitive region.

Regarding your concerns about the potential for the laser to cause significant harm, it’s important to note that while there is a risk of temporary damage to blood vessels, serious complications are rare. The body is generally capable of repairing any minor vascular damage that may occur during the procedure. However, if you experience persistent pain, unusual swelling, or any signs of infection (such as increased redness, warmth, or discharge), it is crucial to seek medical attention promptly.

As for your heart discomfort during the procedure, it could be attributed to anxiety or pain rather than a direct effect of the laser on your blood cells. Pain can trigger a stress response in the body, leading to sensations of discomfort in the chest area. If this continues to be a concern, discussing it with your healthcare provider before your next treatment is advisable.

In summary, while laser tattoo removal can affect blood vessels, the risks are generally manageable and temporary. It is essential to follow post-treatment care instructions to minimize complications and promote healing. If you have any ongoing concerns or experience adverse effects, do not hesitate to consult with your dermatologist or the medical professional performing the laser treatments. They can provide personalized advice and reassurance based on your specific situation.
