A few days after laser treatment, the scab falls off.

　　Laser therapy utilizes light energy of specific wavelengths to penetrate the skin, where it is absorbed by target tissues such as pigmentation and blood vessels in the skin and converted into thermal energy, thereby achieving therapeutic effects. The general reference price for laser therapy ranges from 2000 to 5000 yuan per session, and visible improvement is usually observed within 7 to 15 days. The time required for scabs to fall off after laser therapy varies from person to person, but generally takes 7 to 14 days. For mild laser therapy, approximately 7 days are needed for scabbing to resolve. However, for more intensive laser treatments, approximately 14 days are usually required. Detailed explanations are as follows:

　　Mild laser therapy mainly affects the epidermis (outermost layer of skin) and causes relatively minor damage. It only disrupts the pigment particles in the epidermis, making self-repair relatively easier for the skin. Therefore, the epidermis can usually repair itself relatively quickly after treatment, completing the healing process and shedding scabs in about 7 days.

　　In contrast, more intensive laser therapy reaches the dermis (inner layer of skin), causing more significant damage. In this case, the healing process involves not only the epidermis but also the dermis, including the repair of damaged blood vessels and fibrous tissues. Due to the deeper level of injury, the healing process is more complex and requires more time, so scabs generally fall off after about 14 days.

　　After laser therapy, it is important to keep the treated area clean and dry, avoiding contact with water to prevent infection. Additionally, avoid using irritating skincare products and ensure proper sun protection to promote skin recovery.
