Conclusions

The benefits of using the CO₂ laser rather than a cold‑steel scalpel in periocular surgeries such as blepharoplasty, ptosis, entropion and ectropion, and xanthelasma  excision are discussed in this article. Reduced operation time, less bleeding, superior intraoperative visibility, less bruising and swelling, as well as less pain and discomfort, and a shorter healing period, are some of the benefits of using the laser as a surgical tool.

Furthermore, the CO₂ laser can be used in laser resurfacing treatments for photodamaged skin and acne scars. The efficacy and safety have been demonstrated with this technique since its first introduction 20 years ago. Thermal ablation vaporises superficial layers of tissue providing the tissue rejuvenation. Thermal activation causes immediate tissue contraction and new collagen production to reduce wrinkles and tighten the skin. Patient selection and appropriate preoperative planning and postoperative care are essential for successful outcomes and unwanted side‑effects.

Despite the advances in technology and the introduction of alternative methods for skin resurfacing, the CO₂ laser continues  to deliver the most consistently effective improvement in skin tightening and wrinkle reduction, thus remaining the gold standard for skin resurfacing.
