What treatment can result in hyperpigmentation, hypopigmentation, and/or sensitivity if administered improperly?

The correct answer is that microdermabrasion can result in hyperpigmentation, hypopigmentation, and/or sensitivity if not administered correctly. This treatment involves the mechanical exfoliation of the skin's surface, which can be very effective in improving skin texture and tone. However, if the procedure is performed too aggressively or too frequently, it can lead to irritation of the skin.

Improper technique may result in uneven removal of skin cells, which can cause areas of discoloration due to hyperpigmentation. This is particularly true in individuals with darker skin tones, whose skin is more susceptible to post-inflammatory hyperpigmentation. Additionally, over-exfoliating or using inappropriate equipment or settings can lead to hypopigmentation, where areas of the skin lose their natural pigmentation.

Furthermore, sensitive skin types can react adversely if the procedure is not tailored to their specific needs, resulting in increased redness, swelling, or a burning sensation. This highlights the importance of understanding skin types and conditions to perform microdermabrasion safely and effectively.
