Final answer:
Malea's client with olive skin tones can face skin pigmentation problems if hair removal isn't done carefully. The melanin in their skin offers some UV protection, but improper hair removal can cause pigmentation issues.
Step-by-step explanation:
Malea should keep in mind that her client with olive skin tones can have significant skin pigmentation problems if hair removal is not performed carefully. People with olive skin have a moderate amount of melanin, the pigment that determines the color of hair and skin, which provides some natural protection against the sun's ultraviolet rays.
However, improper hair removal techniques can potentially result in skin pigmentation issues, such as hypo- or hyperpigmentation, where the skin becomes lighter or darker than the surrounding areas. This is particularly a concern for individuals with conditions like albinism or vitiligo, where melanocytes are unable to produce melanin effectively, though these conditions do not directly affect lifespan.
