What is the purpose of using a sunscreen after laser treatments?

Using sunscreen after laser treatments serves a critical role in protecting healing skin from UV exposure. Following a laser procedure, the skin is often more vulnerable and sensitive to environmental factors, particularly ultraviolet (UV) rays from the sun. This heightened sensitivity can lead to complications such as irritation, pigmentation changes, or infections if the skin is exposed to sun damage during the healing process.

Applying sunscreen helps shield the treated area, promoting optimal healing while minimizing the risk of post-inflammatory hyperpigmentation, which can occur when damaged skin receives UV exposure. By safeguarding the skin from UV rays, sunscreen supports the overall recovery after the treatment, ultimately leading to better long-term results and preservation of the skin's quality.

The other choices do touch on benefits but are more indirect or not as central to the essential need of protection during the healing phase. While enhancing results and preventing tanning might be considerations, the primary and most critical purpose in a postoperative context remains the prevention of UV damage.
