The marks left behind by eczema are mostly pigmentation left behind after the healing of skin damage, which usually fades on its own, or can be accelerated by medication, laser treatment or chemical resurfacing to accelerate the absorption of the pigmentation. The marks left behind by eczema belong to hyperpigmentation spots, which is due to the inflammation produced by eczema affecting the metabolism of melanocytes, making the skin color uneven. Overuse of glucocorticoid creams during the onset of eczema is also prone to hyperpigmentation spots. 1. Medication: Hyperpigmentation spots can be treated with topical hydroquinone cream, polysulfonic acid mucopolysaccharide cream and other medications, which can be combined with vitamin C, vitamin E and other oral treatments. 2. Laser treatment: The laser used to treat hyperpigmentation spots is usually dye pulse laser or Q-switched ruby laser. Laser can selectively destroy melanin particles in the skin, promote the metabolism and absorption of pigment particles by cells, and accelerate the fading of hyperpigmentation. 3. Chemical skin resurfacing: topical application of professional concentration of salicylic acid, fruit acid and other chemical reagents with exfoliating properties, to promote epidermal cuticle shedding, stimulate the generation of newborn cuticle, accelerate pigmentation shedding. If there is a willingness to treat the patient, it is recommended to go to a formal medical institutions, find a specialist physician after the interview standardized treatment, in order to avoid adverse consequences.
