Laserresurfacing

Laser resurfacing is a cosmetic procedure that uses focused laser energy to remove or remodel the outer layers of skin in order to improve texture, tone, and the appearance of fine lines, wrinkles, scars, or sun damage. The method relies on controlled ablation or heating of skin tissue to stimulate collagen remodeling and new skin growth.

There are several approaches. Ablative lasers, such as carbon dioxide (CO2) and erbium:YAG lasers, vaporize and remove tissue, producing substantial results but with longer healing times and higher risk of side effects. Non-ablative lasers heat the underlying skin without removing surface tissue, offering milder gains and shorter downtime. Fractional versions of both ablative and non-ablative lasers treat only a portion of the skin in a grid of microscopic columns, allowing faster recovery while still providing improvements.

Indications include wrinkles around the eyes and mouth, sun-damaged or pigmented skin, scars from acne or injury, and uneven skin texture. Candidates should have realistic expectations, healthy skin, and no active infections or certain medical conditions. People with darker skin tones face a higher risk of pigment changes and may require careful laser selection. Medications such as isotretinoin, a history of keloid formation, or active herpes simplex infections are important considerations.

The procedure is typically performed on an outpatient basis, often with topical or local anesthesia, and sometimes with sedative support. Recovery varies by type: ablative treatments usually require several days to weeks of healing with crusting and redness, while non-ablative approaches have shorter downtime. Potential risks include redness, swelling, infection, scarring, and changes in skin pigmentation.

Results accumulate over weeks to months and may require multiple sessions. Protection from sun exposure is essential for maintaining improvements.
