  1. What is the primary target of laser hair removal treatments?

    Answer: Melanin in the hair follicle

    Laser hair removal targets melanin in the hair follicle to selectively damage and reduce hair growth.

  2. Which Fitzpatrick skin types are at highest risk for hyperpigmentation after laser treatment?

    Answer: Types IV-VI

    Fitzpatrick skin types IV-VI are more prone to hyperpigmentation due to higher melanin content in the skin.

  3. What is the role of cooling devices in laser treatments?

    Answer: Protect the epidermis and minimize discomfort

    Cooling devices help protect the epidermis, enhance comfort, and reduce thermal injury during laser procedures.

  4. Which energy-based treatment is best suited for improving skin texture and stimulating collagen?

    Answer: Radiofrequency treatment

    Radiofrequency devices deliver heat to the dermis, which stimulates collagen production and improves skin texture.

  5. Which precaution is critical before performing IPL (Intense Pulsed Light) therapy?

    Answer: Avoid sun exposure and tanning

    Avoiding sun exposure and tanning reduces the risk of burns and pigment changes during IPL treatments.

  6. What is a potential complication of improperly calibrated laser equipment?

    Answer: Burns or pigmentation changes

    Improper settings can result in burns, scarring, or pigmentation changes due to excessive energy delivery.
