You can take a warm shower even immediately after the session. But do not use irritating things such as scrubs or washcloths. If you want, you can wash the area by hand with shampoo. Rinse thoroughly. Do not use extremely hot water. Moisturize the area well after bathing. Do not ignore the articles written unconsciously, do not touch water for 24-48 hours. Laser does not cause any significant sensitivity on the skin.
