What is the main purpose of chemical exfoliation on the skin?

  1. Increases hair growth

  2. Damages the skin in a controlled manner to regenerate damaged skin

  3. Reduces the need for sunscreen

  4. Darkens skin tone

The correct answer is: Increases hair growth

Chemical exfoliation on the skin can help increase hair growth because it removes dead skin cells and unclogs pores, allowing for healthier hair follicles to grow. Option B is incorrect because although chemical exfoliation does involve controlled damage to the skin, its main purpose is not for skin regeneration. Option C is incorrect because chemical exfoliation does not affect the need for sunscreen, as sun protection is important regardless. Option D is incorrect because chemical exfoliation does not have a direct effect on skin tone. Instead, it can brighten and even out skin tone by removing dead cells and revealing new skin.
