Final answer:
It is false that blackheads should be pressed out immediately, as this may cause skin damage. A gentle skincare routine and professional help are preferable for dealing with blackheads.
Step-by-step explanation:
The statement that 'you should press out blackheads on a client with oily skin immediately' is false. It is not recommended to press or squeeze blackheads as this can cause skin irritation and potentially lead to scarring or infection. Instead, a better approach for dealing with blackheads, especially in clients with oily skin, is to use gentle exfoliation, use products that contain salicylic acid or benzoyl peroxide, and maintain a regular skincare routine. A professional facial treatment or visit to a dermatologist can also provide safe and effective ways to manage blackheads.
