Why is it recommended to avoid sun exposure before laser hair removal?

Avoiding sun exposure before laser hair removal is primarily recommended to prevent skin irritation. Excessive sun exposure can lead to skin changes, such as tanning or sunburn, which increases the likelihood of adverse reactions during the treatment. Tanned or damaged skin may absorb the laser energy differently, which could result in discomfort, an increased risk of burns, or other complications during the procedure.

In contrast, maintaining a baseline of untanned skin allows the laser to more effectively target the hair follicles without the interference of skin pigmentation that can occur from sun exposure. This not only helps ensure a safer treatment but also enhances the overall efficacy of the procedure. Additionally, well-prepared skin can recover more quickly and effectively, reducing the potential for irritation post-treatment.
