In short

A 2-week tattoo is a semi-permanent tattoo without needles. Its jagua-based ink only stains the top layer of your skin and turns dark blue to black within 24–48 hours. It fades naturally after about 1–2 weeks as that layer renews itself – faster on hands and feet, slower on the upper arm or back.

A 2-week tattoo sits right between a stick-on tattoo and the real thing. It looks like ink under your skin, not like a sticker on top of it – and it is gone again after one to two weeks. No needles, no pain, no commitment. Here is how it actually works, how long it really lasts and what you can do to make it last longer.

What is a 2-week tattoo?

A 2-week tattoo (also called a semi-permanent tattoo) is a tattoo that colors the top layer of your skin for a limited time. You apply it like a transfer: place it, soak the backing paper, peel it off. Over the next 24–48 hours the ink develops from a faint blue into a dark blue to black that looks like a fresh tattoo.

The big difference to a real tattoo is depth. A tattoo artist uses needles to bring ink into the dermis, the deeper layer of the skin, where it stays for life. A 2-week tattoo stays in the epidermis, the outer layer that your body renews on its own. That is why it fades instead of staying forever.

  • 18+recommended minimum age for Tattup

How does the ink work?

The active ingredient in Tattup ink is the fruit extract of Genipa americana, a tropical fruit from Central and South America also known as jagua. Indigenous communities have used jagua for body art for centuries.

The extract contains genipin. Once the water-based ink sits on your skin, genipin reacts with the amino acids in the proteins of your top skin layer and forms a blue-black pigment. That reaction takes time – which is why your tattoo looks barely there right after applying it and only reaches its full color after one to two days.

Good to knowBecause the color comes from a reaction with your skin, the final shade varies slightly from person to person: from deep navy to almost black. On deeper skin tones the result often looks especially strong.

What happens from day 0 to day 14?

  1. ApplyRight after peeling off the paper the design is light blue and faint. Totally normal.
  2. Let it setNo water, no rubbing, loose clothes. After that you can shower normally.
  3. Full colorThe ink darkens to deep blue or black and looks like a real tattoo.
  4. Peak lookCrisp lines and full color, as long as the area sees little friction.
  5. Natural fadeYour skin renews its top layer and the tattoo fades evenly, without peeling.

How long does a 2-week tattoo really last?

Most Tattups fade after 1–2 weeks. That is roughly the time your outermost skin layer needs to renew itself: a study on forearm skin measured an average turnover of the stratum corneum of 14.5 days. How long your tattoo lasts depends on four things:

  • Body area: less friction and less water contact means longer wear.
  • Daily habits: frequent hand washing, sports with lots of friction or long baths speed up fading.
  • Application: if the backing paper was fully soaked, the whole design transfers evenly.
  • Your skin: skin chemistry and renewal speed differ from person to person.
Body area Wear time Why
Upper arm, shoulder, back Longest Little friction, little water
Inner forearm Long Low friction, highly visible
Chest, ribs, thigh Long to medium Depends on tight clothing
Wrist, hand, fingers Shorter Lots of movement and hand washing
Feet, ankles Shorter Shoe friction and constant movement
Snake tattoo on the upper arm, a spot with long wear time
Small script tattoos on the fingers, which fade faster

How do you make it last longer?

  1. Leave it alone for 8 hours. No water, no rubbing, no tight sleeves while the ink sets.
  2. Warmth helps. After those 8 hours a warm shower or a light sweat helps the color develop deeper.
  3. Pick the right spot. Upper arm, shoulder, back or inner forearm hold longest.
  4. Moisturize after 48 hours. A light, oil-free lotion keeps the skin hydrated. Oily products and body oils make it fade faster.
  5. Skip scrubs. Peelings, exfoliating gloves and hard scrubbing remove the top skin layer – and your tattoo with it.

How is it different from henna and stick-on tattoos?

Who is a 2-week tattoo for?

  • Testers: try a design, size and placement for two weeks before you book a tattoo artist – see try a tattoo before you get it.
  • Occasions: festivals, weddings or holidays. Apply it 1–2 days before so the color is fully developed.
  • Commitment-free: for anyone who loves the look but not the idea of forever – or whose job does not allow visible tattoos.
  • Creators: with our customizer or the AI tattoo generator you can turn your own idea into a 2-week tattoo.

Is a 2-week tattoo safe?

Every cosmetic product sold in the EU needs a safety assessment under the EU Cosmetics Regulation. Tattup ink was tested by a laboratory and rated safe in such a safety report. As with any cosmetic, an allergic reaction can never be ruled out completely, so a patch test makes sense if you have sensitive skin.

Frequently asked questions

How long does a Tattup tattoo last?

Your Tattup fades naturally after about 1–2 weeks – at the pace your top layer of skin renews itself. How long it lasts exactly depends on:

  • the body area (less friction and water = longer wear)
  • your daily habits (friction, water contact, sports)
  • how well you soaked the backing paper
  • your individual skin chemistry

Pro tips to keep it fresh for longer:

  • Leave your Tattup untouched for the first eight hours.
  • After about eight hours, a warm shower or a light sweat helps the color get even deeper.
  • Pick spots with little friction or water contact.
  • After 48 hours, moisturize daily to keep the look fresh.
  • Frequent washing, scrubbing and exfoliating make it fade faster – avoid them as long as you want to wear it.

Our guide shows how long a Tattup lasts on different body parts.

How does Tattup actually work?

Tattup’s little “magic trick” starts when our Special Ink Formula settles into the top most layer of your skin (the epidermis). Over about 24–48 hours, the formula reacts with natural components in your skin, gradually shifting color into a deep navy or black. Timing and shade vary from person to person because everyone’s skin chemistry is a bit unique.

By contrast, standard tattoos use needles to get ink into your dermis (the deeper layer). But Tattup stays in the outer layer, which means it won’t last forever—your epidermis naturally regenerates and eventually takes the tattoo with it.

Are Tattup tattoos waterproof?

They’re definitely water-friendly! Shower, swim and sweat without immediate worries. 💦

Good to know: frequent water contact and rubbing make the tattoo fade a little faster over time. If you want to get rid of it sooner on purpose, warm salt water with a gentle exfoliation helps – see “How do I remove a Tattup tattoo?”.

How do I remove a Tattup tattoo?

A mild exfoliation with warm saltwater usually speeds up fading. You can use a gentle body scrub or a washcloth—just don’t overdo it if your skin gets sensitive.

Note: If you literally just applied the tattoo, you can rinse it off immediately before it sets. But once the ink has sunk in, it’ll need a bit more work (exfoliating, saltwater, etc.) to fade.

Do Tattup tattoos expire?

Yes – unopened and stored correctly (cool, dry and out of direct sunlight), our tattoos stay fresh for about 12 months. After that, the active ingredients slowly lose their power – so it’s best to use them within that time.
