Make sure the area where you are going to paste is very dry. Before picking up the tattoo sticker, thoroughly wash the area to be pasted with water, then wipe it with a paper towel until there is no water left. 

1. The pigmentation stickers use complex pigments, and some even contain certain harmful substances to the human body, such as adhesives and pigments containing heavy metal elements. Some of these dyes are toxic, and the irritation from these substances can easily lead to toxic lesions. Since this kind of decoration directly contacts the human skin surface, it is also prone to cause allergic reactions, such as itching, pain and other allergic symptoms.

2. When you want to remove the tattoo sticker, you can apply a little baby oil on the tattoo. Since most tattoo stickers are waterproof and resistant to soap, wiping with oil is a good option. Exfoliating scrub can also be used on the face or body. You can also use a special tattoo sticker cleaner. You can also apply a thick layer of erasing cream on the tattoo area. Let the erasing cream stay on the skin for about an hour to achieve complete cleaning. Use a towel to wipe off the erasing cream and the tattoo together. Wash away the residues with warm water and hand soap. 

3. The so-called waterproof tattoo stickers are made by spraying a layer of transparent coating on the tattoo stickers, thus achieving a waterproof effect. These waterproof tattoo stickers may cause allergies. They can lead to redness and swelling at the tattooed area. Therefore, do not blindly pursue the so-called waterproof tattoo stickers. The current tattoo stickers are very realistic because most of them are printed with tattoo stickers using color printers. They can be transferred onto the skin. If you use a better printer, the patterns will be much clearer and the clarity of the patterns on the skin will be much higher.
