Leave second skin on for 3 to 5 days in total, unless your artist tells you otherwise. Many artists replace the first sheet after 8 to 24 hours, once the heaviest fluid has collected, then leave a fresh sheet on for 3 to 4 more days. Take it off early if it leaks, lifts at the edges or the skin around it looks angry.
The basicsWhat second skin is
Second skin is a thin, clear, adhesive film, usually polyurethane, sold under names such as Saniderm and Dermalize. It is waterproof but breathable, so it keeps bacteria, friction and clothing off the tattoo while letting the skin breathe. It also holds the fluid a new tattoo produces against the skin, which keeps the surface moist and can mean less scabbing.
TimingHow long to leave second skin on
| Situation | What most artists advise |
|---|---|
| First sheet | Remove after 8 to 24 hours, once fluid has pooled under it |
| Second sheet | Leave on for 3 to 4 more days on clean, dry skin |
| Total time | 3 to 5 days, rarely more than 6 |
| Single sheet only | Up to 3 or 4 days if it stays sealed |
| Leaking or lifting | Take it off now, wash and carry on with aftercare |
Your artist knows the skin, the placement and the work, so their timing comes first. Some films can stay on for up to a week, but most artists stop at 5 days because skin under film for too long can become soft, itchy or irritated by the adhesive.
Under the filmFluid under second skin, normal or a leak?
In the first 24 hours a pocket of cloudy, ink-coloured fluid under the film is normal. It is plasma, a little blood and excess ink, and it is exactly what the film is meant to hold. A leak is different. If fluid escapes at the edges or the seal opens and lets air in, the barrier is gone.
- Normal. A tinted pocket of fluid that stays sealed, mostly in the first day.
- Change the sheet. A large bubble that is pulling the film, or fluid near the edges.
- Take it off. Fluid escaping, edges lifting or the seal open to air.
Step by stepHow to take second skin off
- Wash your hands thoroughly.
- Take it off in a warm shower. Let the water run over the film for a few minutes to loosen the adhesive.
- Find a corner and fold it back over itself, peeling low and parallel to the skin, slowly, in the direction of hair growth.
- Stretch the film along the skin as you go rather than lifting it up. Never rip it off.
- Wash the tattoo gently with lukewarm water and a fragrance-free cleanser, using your fingertips only.
- Pat dry with clean paper towel and let it air dry for 10 minutes.
- Apply a very thin layer of a recovery formula made for healing skin.
If an edge is stubborn, soak it again rather than pulling harder. Pulling can lift fresh skin and take ink with it.
Living with itSleeping and showering with second skin
Both are fine. The film is waterproof, so keep showers short and lukewarm and keep the spray off the area where you can. Do not soak in a bath, pool, the ocean or a hot tub. At night, sleep on clean sheets and avoid lying on the tattoo while the film is fresh. Read more on showering with a new tattoo.
- An itchy, raised or blistered rash around the adhesive, which can be a reaction to the film.
- Redness that keeps spreading beyond the tattoo after the first day.
- Heat, increasing swelling or pain that gets worse rather than better.
- Cloudy yellow or green fluid, a bad smell or a fever.
Spreading redness, heat and fever can be signs of infection. See a doctor the same day and read the signs of an infected tattoo.
Once it is offWhat to do once second skin is off
From here your tattoo heals like any other. Wash gently 2 to 3 times a day and follow each wash with a thin layer of LOCK, the recovery complex made for the 14 days that decide how much ink stays. Expect light flaking from around day 4 to 7. Leave it alone, and read what is normal for peeling and itching.
QuestionsSecond skin, answered
Can I leave second skin on for 7 days?
Some films are made to stay on for up to a week, but most artists set 5 days as the limit. Longer can leave the skin soft and irritated under the adhesive. Follow your artist’s timing.
Is it normal for ink to collect under second skin?
Yes. In the first day, plasma, a little blood and excess ink gather under the film. As long as it stays sealed, it is normal.
Should I take second skin off in the shower?
Yes. Warm water loosens the adhesive so the film peels away gently. Peel it slowly back over itself, never straight up.
Can I put second skin back on after taking it off?
Only a fresh sheet, on clean and completely dry skin, and only if your artist advises it. Never reuse a sheet.
Does second skin make a tattoo heal faster?
It keeps the skin moist and protected, which many artists find means less scabbing. The surface still takes 2 to 4 weeks to heal and the skin underneath several months.
3 to 5 days, then gentle aftercare.
Swap the first sheet after about a day, leave the second on for 3 to 4 days, peel it off slowly in the shower and move straight into thin layers of a recovery formula. If it leaks or the skin reacts, take it off early.
