What should patients avoid post-laser treatment to ensure proper healing?

To ensure proper healing after laser treatment, it is crucial for patients to avoid sun exposure. Sunlight can interfere with the healing process by causing inflammation and increasing the risk of hyperpigmentation, particularly on treated areas. Sensitive skin that has undergone laser therapy can react adversely to UV rays, potentially leading to complications or prolonged recovery time.

While exercise and hot showers might also be discouraged in certain contexts, their impact on healing may not be as critical as preventing sun exposure. Exercise can increase circulation and body temperature, potentially irritating the treated area. Hot showers can lead to increased redness and swelling. However, these factors generally do not carry the same level of risk as sun exposure, which can directly affect the skin's healing response.

In summary, avoiding sun exposure is vital for protecting the skin and promoting effective healing after laser treatment, making it a priority in post-treatment care instructions.
