Fractional laser creates microscopic wounds on the skin, too small to be seen with the naked eye. By stimulating compression regeneration, it removes old epidermal tissue, reshapes collagen in the dermis, and promotes skin renewal. This process tightens the skin, improves pigmentation, and helps flatten scars.During treatment, a matrix of tiny white dots appears where the laser penetrates. The epidermis gradually heals within 8 hours, and the scabs at these sites shed within 7 days, restoring the skin to normal. Additionally, new epidermal skin regenerates within 24 hours post-treatment, while internal collagen regeneration takes approximately 6 months. It generally requires 3 to 6 months for the skin tone to return to normal.
What precautions should be taken after fractional laser treatment?
1. Maintain wound cleanliness and hygiene
After fractional laser treatment, the skin will develop small wounds that typically heal within 24 hours. During this period, keep the wounds clean and hygienic, avoiding contact with dirty water to prevent infection. Additionally, the treated area may experience mild redness, swelling, and pain. Applying an ice pack can help constrict blood vessels and stop bleeding, while also promoting skin healing, reducing inflammation, and alleviating discomfort.
2. Practice thorough sun protection
UV exposure accelerates skin aging and stimulates melanin production. Following fractional laser treatment, the skin's resistance to viruses is reduced, increasing susceptibility to scarring and impairing local tissue repair. Furthermore, avoid makeup for one month, as cosmetics contain chemicals and heavy metals that may enter the wounds and hinder skin tissue healing.
3. Intensify Hydration
The treatment damages the skin's stratum corneum, reducing its moisture-retaining capacity. Combined with localized heat causing excessive water evaporation, this often leads to dryness and tightness. After treatment, promptly replenish hydration by drinking ample water or using hydrating masks.
Important Reminder
After fractional laser treatment, wounds will gradually heal. Scabs typically take about 7 days to naturally shed. Do not pick at them, as this can tear the wound, slow recovery, and cause scarring.During recovery, consume plenty of fresh vegetables and fruits rich in minerals and vitamin C to support cellular regeneration. Avoid sugary foods, spicy or irritating dishes, and strong tea or coffee.
