Because humans have four basic blood types, which are not integrated with each other, and animals have more blood types, I believe people with a little common sense will understand the possible harm caused by the integration of different blood types between humans and animals. Animals will have parasites or carry various harmful viruses, which will be very troublesome once they are transmitted to humans.

Simple blood tattoos have no coloring effect. When the blood concentration or other factors reach a certain level, the illusion of coloring will occur. In fact, the principle is the same as scar redness. When you drink alcohol or exercise vigorously, your blood circulation will speed up and turn red, but not all people get tattoos like this.

Matters needing attention

1. After tattooing is completed for three to four hours, wash the tattooed area with warm water, then dry it with a sanitary towel, keep it dry and clean it daily. You can only take a bath, not a bath.

2. Do not apply any ointment other than tattoo ointment, so as not to cause fading and damage the overall aesthetic feeling.

3. Don't swim, sauna, bask in the sun or go into the sea before the tattoo is healed.

4. It is normal to have scab, peeling and itching in three to five days. Never scratch, the scab will fall off naturally. Make-up water can be used properly at this time.

5, tattoo If the tattoo is at the joint or the part that is easy to be pulled, pay attention to the action when scabbing, so as not to scab and crack, which will affect the future appearance.

6. I don't want it after tattooing, so I can't wash it right away. It takes a year for the wound to heal before it can be washed with laser.
