How to Prepare for Your Tattoo
A little preparation makes a big difference in how your tattoo looks and heals.
Stay Hydrated
Drink plenty of water in the 24 hours before your session. Well-hydrated skin takes ink more smoothly and heals faster.
Eat a Full Meal
Don't come in on an empty stomach. A solid meal 1–2 hours before keeps your blood sugar stable during the session.
Moisturize Skin
Keep the area moisturized in the days leading up. Avoid sunburn — burned or peeling skin can't be tattooed safely.
Wear Comfortable Clothing
Choose clothing that allows easy access to the area being tattooed. You may be sitting or lying for extended periods.
Avoid Alcohol
Don't drink alcohol for at least 24 hours before your appointment. Alcohol thins blood and increases bleeding during the session.
Know Your Idea
Bring reference images, notes, or a sketch. The more clearly you can communicate your vision, the better the result.
