How long after fractional laser treatment can I wash my face?

　　The principle of fractional laser involves emitting high-energy laser beams to stimulate skin wound repair and tissue remodeling. The general reference price for fractional laser treatment is 3000-6000 yuan per session, and visible improvement is usually observed within 7-15 days. Under normal circumstances, patients can wash their face 7-10 days after fractional laser treatment, although the exact timing may vary among individuals. The analysis is as follows:

　　If the patient's skin has strong recovery ability and there are no obvious symptoms such as redness, swelling, or exudation, gentle face washing with water can be performed seven days after the fractional laser treatment. However, rubbing should be avoided, and hot water or facial cleansers should not be used.

　　If the patient's skin shows a significant reaction, such as noticeable redness, swelling, or minor exudation, face washing should be delayed until 10 days or even longer after the treatment. During this period, patients should avoid direct contact with water on the treated area to prevent infection and promote wound healing. Normal face washing can be resumed only after the scabs have completely fallen off and a physician confirms that the skin has adequately stabilized. For patients with weaker skin recovery ability, a waiting period of about 10 days is also required to allow sufficient skin recovery.

　　If undergoing fractional laser treatment, it is recommended to visit a reputable hospital and follow the guidance of a qualified physician. Additionally, avoid using overly irritating facial cleansers or cosmetics.
