1. Aggravate melanin deposition: Although laser freckle removal can quickly remove freckles, the treatment results under destructive conditions may also be aggravated by large-scale damage to epidermal cells and skin repair function.
2, dry skin, chapped: laser freckle is to treat the skin surface, need to peel off the stratum corneum, in a cold environment, it is easy to cause vasoconstriction, water loss, slow blood flow or purple congestion. The lack of skin care causes skin tension, wrinkling and even chapping, infection and ulceration, which accelerates the aging process of skin.
3, skin thinning appears red blood: laser freckle first peels off the epidermal cells of the skin, which is easy to cause skin thinning and prominent capillaries. When heated, exercised or emotionally excited, blood vessels dilate, blood flow accelerates, and the face turns red, that is, red blood.
4, the skin becomes sensitive: due to the damage of epidermal cells, the skin becomes fragile and more sensitive. It is easy to produce rash, itching and desquamation, and bacterial infection is easy to fester and even cause skin cancer.
Second, the sequelae of laser freckle
1, burn the skin, if the laser energy is too large during the diagnosis and treatment, the skin can't bear it, it will cause redness and swelling, and even burn the subcutaneous structure of the epidermis, causing irreparable consequences.
2. Leave a scar. Generally speaking, because of its high accuracy, the size and depth of diagnosis and treatment can be strictly controlled, and no scar will be left after operation. However, if the operation is improper, it will cause deep burns, resulting in concave scars or hypertrophic scars.
3, pigmentation. That is to say, after laser freckle removal, the skin color becomes darker, which is partly caused by the emergency response of individual skin to laser stimulation and the precipitation of inflammatory pigment after operation. It usually subsides spontaneously within 2-3 months after operation, which is a temporary phenomenon.
