Final answer:
Facial scrubs are not recommended for acne-prone or sensitive skin as they can cause further irritation. Instead, gentle, non-abrasive cleansers should be used with lukewarm water and without scrubbing.
Step-by-step explanation:
A facial scrub is generally not recommended for individuals with acne-prone or sensitive skin. The mechanical action of scrubbing can irritate and worsen acne conditions by causing further inflammation and potential scarring. It is advised for people with this skin type to use alcohol-free products, avoid harsh astringents, exfoliants, and to wash with lukewarm water instead of extreme temperatures.
Applying a gentle, non-abrasive cleanser using the fingertips and avoiding any scrubbing motion can help to manage sensitive or acne-prone skin more effectively.
It is also important to reduce the microbial load on the skin, which can be achieved through gentle cleaning combined with the use of mild chemicals that do not irritate or dry out the skin. This supports the skin's natural barrier and helps to prevent the severity and frequency of acne flare-ups.
