Which of the following is recommended as aftercare advice for a patient post-laser treatment?

After undergoing laser treatment, it is crucial for the patient to avoid sun exposure. This recommendation is particularly important because the skin may be more sensitive and vulnerable to damage after the procedure. Sun exposure can lead to complications, such as hyperpigmentation, irritation, or delayed healing. Shielding the treated area from sunlight helps to ensure that the skin can heal properly and reduces the risk of adverse effects.

Proper aftercare, including avoiding direct sunlight, is essential to achieve the best results from the laser treatment and to promote skin health. Other aftercare practices may include using broad-spectrum sunscreen, wearing protective clothing, and following any specific guidelines provided by the healthcare provider.
