This issue varies greatly from one person to another. Generally, we do not recommend patients to use laser treatment for moles over 5mm, because the self-healing ability of the larger skin is limited and will leave more obvious scars. Secondly, deeper moles will leave a scar similar to the pits after acne, so we often recommend patients to have two dots, one month after the first one, and if it grows again, we can make up the dots again, some patients even have to have three or four dots. Again, some patients have scar system (which cannot be diagnosed in advance), so for others, a small trauma can be easily recovered, but for such patients, a big scar will grow, of course, the distribution of such people in the population is relatively small. Generally, if you take good care of your moles, avoid water and light (sunlight will cause pigmentation in the spotted area), you can achieve better results and basically the same color as the surrounding skin.
