Getting a tattoo may probably feel like a simple decision; pick a design you love, find a good artist, and you're good to go. After all, tattoos are everywhere now, across age groups, styles, and trends.

But there's a side we don't really talk about enough.

A tattoo isn't just about how it looks; it's a procedure that involves needles, chemicals, and your skin reacting to both. And while it's widely accepted today, it's still not completely risk-free.

So before you get inked, it's worth knowing what actually goes into it. We spoke to Dr Rema Devi TJ, Consultant Dermatologist at KIMSHEALTH, Thiruvananthapuram, to break down what you should keep in mind before making it permanent.

What's Inside Tattoo Ink?

Tattooing may look like surface-level art, but it goes much deeper. According to Dr Rema Devi TJ, tattoo ink is made up of two key components:

Pigments

"These are what give tattoos their colour. Earlier, pigments were derived from natural sources like minerals and carbon. Today, most inks use organic azo pigments, which are also commonly used in industrial products like plastics and textiles," said Dr Devi.

Carriers (Vehicles)

These are liquids that help the pigment stay evenly mixed and allow it to be injected into the skin. Common ingredients include distilled water, alcohol, glycerine, and propylene glycol.

Some commonly used pigments include titanium dioxide (white), carbon black, iron oxides (red/brown), and metals like chromium or cobalt for green and blue shades.

"However, a key concern is that some inks, especially older or unregulated ones, may contain heavy metals like mercury, lead, or antimony as contaminants. From a medical perspective, tattooing involves breaking the skin barrier and depositing foreign pigments into the dermis, which is why safety, hygiene, and long-term monitoring become crucial," warned Dr Devi.

Who Should Be Extra Careful?

Not everyone's skin reacts the same way to tattoos. In some cases, it's best to avoid or delay getting one.

You should be cautious if you have:

• A tendency to develop keloids or thick scars
• Bleeding disorders or are on blood-thinning medication
• A weakened immune system (due to conditions or treatments)
• Uncontrolled diabetes
• Skin conditions like psoriasis, lichen planus, or vitiligo
• Any active infection (bacterial, fungal, or viral)

People with a history of metal allergies should also be careful, as certain pigments can trigger reactions. In such cases, a patch test may help assess sensitivity beforehand.

Ink Safety and Hygiene: Non-Negotiables

The safety of your tattoo depends heavily on the quality of ink and hygiene practices.

Always ensure that only sterile, approved inks are being used
Avoid studios that use industrial or non-medical grade pigments
Make sure the artist uses single-use sterile needles and disposable ink caps

Poor hygiene or improper sterilisation can lead to serious infections. Choosing a reputable and clean tattoo studio is just as important as choosing the design.

Procedural Precautions

There are certain things that should never be overlooked during the tattooing process:

• Avoid getting tattoos over moles or suspicious skin lesions, as this can make early detection of skin issues difficult
• Be mindful of large-area tattoos, especially if it's your first time

These small precautions can make a big difference in the long run.

Possible Risks and Complications

Like any procedure involving the skin, tattooing comes with both immediate and delayed risks.

Immediate reactions may include:

• Pain
• Redness (erythema)
• Bleeding
• Infection

Certain pigments, especially those containing metals, can also cause burning or swelling during MRI scans later on.

Delayed complications can include:

• Allergic reactions (commonly linked to red pigments)
• Itchy bumps, swelling, or raised nodules
• Thickened scars or keloids
• Sun-related reactions, especially with yellow pigments
• Granulomas-small lumps that can appear even years later as the body reacts to the pigment

Aftercare: What You Do Next Matters

Getting the tattoo is just one part of the process, aftercare plays a huge role in how your skin heals.

• Keep the area clean and dry
• Use prescribed creams or antibiotics if advised
• Avoid direct sun exposure, which can affect both healing and pigment
• Watch out for signs like persistent redness, discharge, or itching

If something doesn't feel right, don't ignore it, get it checked.

Bottomline

Dr Devi concluded, "A tattoo may feel like a creative decision, but it's also a medical one in many ways. Knowing what goes into the process-and how your skin might respond-can make all the difference between a good experience and a complicated one."
