How a Second Skin Works
A second skin shields your tattoo from the outside world. While this extra layer is present, your body begins to heal the wound that lies underneath. It quickly forms its protective layer of skin over the top of your tattoo. This means, when you peel off the artificial second skin, your tattoo is protected by a naturally formed layer.
A second skin also acts as a barrier to germs and bacteria, protecting your tattoo at its most vulnerable stage. They allow oxygen to reach your tattoo while at the same time remove surplus moisture vapor, which can slow down the healing process.

How To Remove Second Skin
Test an edge: Pick an edge of the bandage and peel it away. If it’s difficult to remove, try taking a warm shower to help reduce the stickiness
Remove slowly: Pull the second skin off slowly. It’s very similar to removing a plaster. If you pull too quickly, it’s going to sting. You might also damage the new layer of skin underneath. Just go slowly, and you’ll be fine
Clean: Make sure you wash your tattoo carefully after removing the bandage and apply moisturizer
Use your cream/moisturizer for at least a month in a daily basis
It’s totally normal to see some ink or blood under the bandage. This will usually appear within the first day. If you want to, you can replace the old dressing with a new one, following the application instructions.
You can leave a second skin on for as long as it feels comfortable to you. Most people remove it after three to four days. The same bandage shouldn’t be worn for longer than seven days, though — remove it to clean your tattoo. Second skins are great, but they aren’t miracle workers. In areas that bend or flex, they don’t last as long as areas that stay still.
