Losing weight generally does not affect tattoos. Because too much body fat will make the body fat, the skin of the body will open wider with the needs of the body. If you get a tattoo before you lose weight, and you lose a lot of fat at the place where you just got the tattoo, it will affect the tension of your skin, thus affecting the beauty of the tattoo. For example, the belly is usually the place with the most fat accumulation, and the focus of weight loss is on the belly, so if you tattoo on your stomach, it is likely to affect your appearance, and the degree of influence varies from person to person. But generally speaking, the amount of weight loss needed to achieve the degree of aesthetic influence is quite large, but for more people, such a large amount of weight loss is not needed, so tattoos are generally not affected.
