Laser resurfacing uses focused light to create a controlled thermal injury in the skin, which stimulates a powerful wound-healing response. This process promotes the synthesis of new collagen and elastin, removes photodamaged epidermal cells, and remodels the dermal matrix. From a healthspan perspective, this reverses key aspects of cutaneous aging, potentially reducing the local burden of senescent cells and improving skin barrier integrity.
Verdict

Protocol
- Ablative treatments may require only a single session, while non-ablative series often involve 3-5 sessions spaced a month apart.
- Maintenance treatments are typically performed every 1-5 years depending on laser type and individual aging.
Flags
- Procedure must be performed by a board-certified dermatologist or plastic surgeon.
- Risk of post-inflammatory hyperpigmentation is higher in darker skin tones (Fitzpatrick IV-VI).
- Ablative procedures require significant downtime (1-3 weeks) and meticulous aftercare.
- Contraindicated for individuals on medications like isotretinoin or with active skin infections.
- Strict sun avoidance is mandatory post-procedure to prevent complications.
