Although mole spotting is a minor issue, it is actually really encountered a lot of troubles and disputes about it. First of all, let’s introduce what is a mole. A nevus is medically called a nevus cell or melanocytic nevus, which is a skin manifestation caused by the increase of melanocytes in the epidermis and dermis. It contains intradermal nevus, junctional nevus and mixed nevus. Generally speaking, junctional nevi have proliferative activity, and nevi in easy-to-friction areas such as foot plates and palms are more prone to malignant changes, so it is necessary to be vigilant and early removal is generally recommended. So how does laser remove moles? Currently, the most commonly used laser is the pulsed CO2 laser, which can act on the water in the tissue and vaporize the mole tissue. By precisely vaporizing the mole tissue, it can make the mole tissue disappear completely with minimal damage to the normal skin next to it, which can heal on its own and generally leave no visible scars. Although theoretically, moles can be completely vaporized by laser without causing obvious scars, in practice, we find that some moles can still recur even though there is no trace left in the treatment; while some other deeper and larger moles are difficult to be vaporized completely at one time, which may cause obvious scar formation if removed completely. Therefore, before treatment, both doctors and patients need to clarify that this situation is an objective existence to avoid unnecessary disputes. And the doctor should try to completely remove the pigmented mole during the treatment to reduce the possibility of recurrence. Even if the mole is removed cleanly, some other patients may find their nevus punctures have redness or even redness, which is related to the reaction of skin healing, and for some larger and deeper moles and patients with the tendency of scar growth, scarring may be difficult to avoid. After treatment, there are some other things that need to be noted: 1. After surgery, you should rub antibiotic ointment or epidermal growth factor gel externally to ensure the wound surface is moist and clean, which can generally heal within 7-10 days; 2. The wound may feel a little itchy after surgery, do not scratch it, and do not peel off the scab, let the wound heal naturally; 5 Do not eat spicy and stimulating food after surgery to prevent excessive congestion and redness of the wound. If a recurrence does occur, the next treatment should generally be carried out only after an interval of more than 3 months. Laser mole spotting alone can cause the wound to be too large and exceed the healing ability of the skin, so in order to reduce the scar, we would recommend surgical removal. It is recommended that you go to a regular public hospital and choose an experienced skin laser aesthetic surgeon.
