Tattoo artists see the same preventable mistakes constantly. Clients turn up dehydrated, hungover, sunburnt, on aspirin or freshly moisturised. The session goes ahead but the working surface is worse than it could have been. Healing takes longer. Touch-ups are needed. Sometimes the artist has to refuse work and reschedule. None of this is necessary if you know what to avoid.

This page is the consolidated do-not list. We have full pages on most individual topics elsewhere. Use this as your single checklist in the days before your appointment.

The Big Four

Do Not Drink Alcohol in the 24 Hours Before

Alcohol thins the blood significantly and stays in the system for hours after the last drink. Tattooing on a freshly drunk or hungover body bleeds more, which dilutes the ink and produces patchier saturation. Most reputable studios will refuse to work on visibly intoxicated clients. Hangover also lowers pain tolerance and makes nausea more likely during the session.

Do Not Take Aspirin or Ibuprofen 24 Hours Before

NSAIDs are blood thinners. Even normal over-the-counter doses meaningfully increase bleeding during a tattoo session. Paracetamol is fine because it does not affect platelet function. If you regularly take prescription blood thinners for medical reasons, speak to your GP and the artist at consultation. Do not self-stop prescribed medication for a tattoo.

Do Not Get Sunburn or Tan Close to the Appointment

UV exposure inflames the skin for up to 2 weeks even when no visible burn shows. Tattooing through inflamed skin produces patchier ink absorption. Sunburn rules out the session entirely until the area has fully recovered. Skip sunbeds 2 weeks before. Cover the planned tattoo area with SPF50 if you cannot avoid sun. Let any fake tan fade fully.

Do Not Moisturise on the Day of the Session

Moisturiser leaves an invisible film on the skin even after rubbing in fully. That film interferes with stencil adhesion and ink absorption. Daily moisturising for 2 to 4 weeks before the appointment is helpful. Same-day moisturising is harmful. The cut-off is the morning of the day before.

The Full Avoid List

Do Not Skip Food

Empty stomach amplifies pain, increases fainting risk and makes you feel rough. Eat a balanced meal with protein and complex carbs 1 to 2 hours before. Bring snacks for sessions over 2 hours.

Do Not Drink Excess Caffeine

Coffee, energy drinks, pre-workout and strong tea raise heart rate, amplify anxiety and mildly thin the blood. One small cup is fine for regular drinkers to avoid withdrawal. More than that within 4 hours of the session is a problem.

Do Not Show Up Post-Gym

Sweat carries bacteria onto the working surface. Adrenaline amplifies pain perception. Muscle tension makes the area harder to tattoo. Train the day before or after, not the morning of.

Do Not Shave on the Day

Fresh shaving leaves micro abrasions that sting during tattooing and increase infection risk. Either shave 1 to 2 days before or let the artist do it at the studio with a sterile single-use razor.

Do Not Use Numbing Cream Without Telling the Artist

Numbing cream changes the working surface in ways the artist needs to know about. Tell them at consultation if you plan to use it. Some artists prefer not to work with it. Showing up with cream already applied is the wrong way to find out.

Do Not Arrive With Heavy Perfume or Deodorant

These products leave residue on the skin that interferes with stencilling and adds unnecessary chemicals to the working surface. Skip them on the day of the appointment, especially near the planned tattoo area.

Do Not Show Up Sick

Cold, flu, fever or stomach bug all mean reschedule. Your immune system is already working on the illness. Adding the trauma of tattooing slows recovery from both. Your pain tolerance drops too. Reschedule honestly with 48 hours notice and most studios transfer the deposit.

Do Not Bring an Entourage

One supportive friend is fine. A group of five is disruptive. The studio is a working environment not a party venue. Multiple voices in the room slows the artist and can make you self-conscious during a session that needs focus.

Do Not Take New Drugs or Supplements

Anything new you start in the week before could cause an allergic reaction or interact with the tattoo process. Stick with your regular medication and supplements. Tell the artist about everything you take at consultation.

Do Not Be Late

Late arrival rushes prep, shortens the session and stresses both client and artist. The first 30 minutes of the appointment are consultation reconfirmation, stencilling and setup. Skip those and the tattoo gets worse. Arrive 15 minutes early.

Alcohol and caffeine thin the blood and can make the tattooing process harder. Coming to your appointment after drinking is unethical to your artist and to your own result.

The 24 Hour Window

The 24 hours before the appointment matter most. In that window the body responds most to whatever you put into it. The avoid list compresses to this. No alcohol from the previous evening. No aspirin or ibuprofen. No new skincare products. No tanning bed visits. No fasting. No intense exercise. Pre-existing healthy state is fine. Big lifestyle changes are not.

The Day Itself

Day of the appointment is where the surface-level avoids apply most. No moisturiser or lotion on the planned tattoo area. No perfume or deodorant near it. No fresh shave that morning. No new clothing dyes against the area. No gym session before. No coffee load. No skipped meals.

Positive habits replace these. Eat a balanced meal 1 to 2 hours before. Drink water through the morning. Shower with mild soap, pat dry. Wear loose comfortable clothes. Arrive 15 minutes early. Box breathe in the waiting area to settle nerves.

Why These Mistakes Persist

Three reasons most clients still make these mistakes. First, the advice is often delivered piecemeal across multiple sources rather than in one consolidated list. Second, clients underestimate how much these things matter, treating them as nice-to-haves rather than essentials. Third, the consequences are not always visible immediately. A bit more bleeding during the session is invisible to the client. The patchier ink saturation only shows up weeks later in the healed result.

The reality is that getting these basics right separates clean healed tattoos from problematic ones. The artist can deliver brilliant work on properly prepared skin. The same artist working on compromised skin produces work that does not match their portfolio.

Thinking It Through Before You Book

Plan the 24 to 48 hours before your appointment around this list. No alcohol the night before. No NSAIDs. No tan or sunburn. No moisturiser day of. No gym, fresh shave or excess caffeine the morning of. Eat properly, sleep well, hydrate. The session will go significantly better.

Practical Questions That Come Up

What If I Slip Up on One of These?

Tell the artist when you arrive. Honesty is rewarded. They may proceed with caution, reschedule or adjust technique. Better to disclose than to have them figure it out mid-session and lose trust.

Are These Rules the Same for Small Tattoos?

Mostly yes. Short sessions are less affected by some factors like empty stomach. The bleeding-related rules around alcohol and NSAIDs apply equally to a 30 minute tattoo as to a 6 hour one.

How Strict Is the No Alcohol Rule?

One drink 24 hours before is borderline. Two or more drinks the night before is a clear problem. Anything that morning is grounds for refusal at most studios. The cleaner answer is none from 24 hours before. The body recovers from a sober night quickly.

Does CBD Count as a Drug to Avoid?

CBD oil or supplements are generally fine in normal doses. Cannabis itself is best avoided for the same anxiety and unpredictability reasons as alcohol. If you regularly use CBD, mention it at consultation but no need to stop.

For positive prep see what to do before getting a tattoo. For coffee specifically see should you drink coffee before a tattoo. The full tattoo preperation guide covers the rest.

The summary in one line. The big four to avoid. Alcohol within 24 hours. Blood-thinning painkillers. Sunburn or fresh tan. Moisturiser on the day. Add to that excess caffeine, gym sessions, same-day shaving, perfume, showing up sick, skipping meals and bringing an entourage. Each has a concrete reason. Skip them and the session goes significantly better.
