Final answer:
Option C. The skin type associated with maintenance and preventative care is normal skin. It is characterized by a well-balanced, small-pored, smooth texture, and the care for this skin type focuses on maintaining balance and preventing potential skin issues.
Step-by-step explanation:
The skin type that is associated with the treatment goals of maintenance and preventative care is normal skin. This type of skin is well-balanced and does not suffer from severe oiliness or dryness. Normal skin has a good balance of moisture, small pores, and a smooth texture.
The treatment goals for normal skin revolve around maintaining its natural balance and preventing potential skin issues, such as premature aging or environmental damage. In contrast, oily skin would require different care, often aimed at reducing excess oil and preventing breakouts, while combination skin would involve addressing both oily and dry areas separately.
