Clients may be unsure about the risks of sun exposure following treatments like chemical peels, laser treatments, or waxing. Educating clients on the importance of avoiding direct sunlight and using high-SPF sunscreen post-treatment is crucial to prevent complications such as hyperpigmentation or sunburn. Providing guidelines on how long to avoid sun exposure and recommending protective measures, like wearing hats or staying in the shade, helps clients take the necessary precautions to protect their skin and enhance treatment results.
