What should be the immediate post-treatment instruction for clients after laser hair removal?

After undergoing laser hair removal, the immediate post-treatment instruction of applying sunscreen and avoiding sun exposure is vital for the client's skin health and safety. Laser treatments can make the skin more sensitive and vulnerable to sun damage. Exposure to UV rays can lead to issues such as hyperpigmentation, irritation, or burns, jeopardizing the results of the treatment and potentially harming the skin.

Clients are also advised to apply broad-spectrum sunscreen with a high SPF whenever they are exposed to the sun to protect the treated areas. This instruction is particularly important since the skin may be red or irritated following the procedure, and protecting it from the sun helps in the healing process.

In contrast, exfoliating the area immediately after treatment can irritate the sensitive skin, and hydrating with hot water could exacerbate any inflammation or discomfort. Using heavy makeup might also clog pores or irritate the skin post-treatment, which isn’t advisable as the skin needs to breathe and recover after the procedure.
