Which step is prohibited immediately following the initial procedure?

• A. Discontinue cleansing entirely
• B. Use alcohol-based products on the area
• C. Apply cosmetics over treatment area
• D. Touch the area with unwashed hands

Answer: (C)

After an initial procedure, the skin’s protective barrier is temporarily damaged and healing begins, so the area must be kept clean, free from irritants, and protected from contamination. Applying cosmetics over the treatment area is not allowed because makeup introduces substances onto the healing skin, which can irritate or inflame it, potentially trap bacteria, clog pores, and hinder proper healing. In the immediate post-procedure period, you want to avoid anything that could irritate or contaminate the site.

Other steps are also discouraged for good reasons: cleansing should continue but be gentle rather than discontinued entirely, so the area isn’t left dirty or prone to infection; alcohol-based products should be avoided because they can dry and irritate the newly treated skin; and touching the area with unwashed hands increases the risk of introducing bacteria and causing infection. The emphasis is on protecting the healing area, which is why cosmetics are specifically prohibited right after the procedure.
