Which of the following should be avoided by patients after laser treatment?

Patients should avoid sun exposure after laser treatment because their skin may be particularly sensitive and vulnerable to damage during the healing process. Laser treatments often lead to increased susceptibility to sunburn and hyperpigmentation, especially in areas that were treated. Direct sunlight can disrupt the healing of the skin and potentially lead to complications such as prolonged redness, scarring, or uneven skin tone. Clients are usually advised to use sunscreen and protective clothing when going outside, as this helps ensure that the results of the laser treatment are optimal and that the skin heals properly.
