3D fractional erbium laser (Eurostar) is a new generation of high-power erbium laser imported from Germany using three-dimensional fractional technology, using VSP adjustable rectangular pulse width technology to precisely regulate the laser pulse width, compared with the traditional erbium laser, higher safety, better efficacy and shorter recovery period. 1, clinical indications Scar removal Wrinkle removal, skin tightening Acne and acne pits Pore reduction, oil control Stretch marks removal 2, principle: for scars, acne pits, large pores and fine lines around the eyes, 3D fractional erbium laser removes abnormal tissue and rough uneven epidermal layer through tissue vaporization; dermal collagen regeneration and remodeling through moderate controlled photothermal damage effect. 3, treatment process: treatment with external lidocaine cream anesthesia, pain is not obvious, depending on the site treatment time generally varies from 2-10 minutes, after treatment can go home, does not affect work life. 4, post-operative care: after treatment there will be a local burning sensation, can be local ice to reduce discomfort, some people will be scabbed with the treatment site, with the use of skin regeneration spray, use about 5-7 days, to be natural scab off after the spray can be stopped, appropriate avoid fishy spicy food can be. 5.Treatment effect.
