After an Intense Pulsed Light (IPL) treatment, it's important to take certain precautions to protect the skin and ensure optimal results. This includes avoiding prolonged sun exposure, hot showers or baths, exfoliating products, touching the treated area, and heat sources such as saunas, steam rooms, and hot tubs. UV rays from the sun can increase the risk of sunburn, skin damage, and hyperpigmentation, while heat can increase skin sensitivity and redness. Exfoliating products can further irritate the skin and touching the treated area can introduce bacteria and increase the risk of infection.
