Final answer:
Individuals with dry skin usually prefer liquid foundation to mineral makeup, as the latter can accentuate dryness. Liquid foundation often contains moisturizers, making it more suitable for dry skin.
Step-by-step explanation:
The person who often prefers liquid foundation over mineral makeup is typically someone with dry skin. Mineral makeup can sometimes be shiny and too drying, which is not suitable for dry skin as it may highlight dry patches and does not provide enough moisture. On the other hand, liquid foundation is often formulated with moisturizing agents which can hydrate the skin and give a more dewy finish, making it a better option for those with dry skin.
Glands that produce a lipid-rich substance containing proteins and minerals are sweat glands. This substance, known as sweat, helps to protect the skin by maintaining its barrier function and pH balance. Although sweat is primarily associated with body temperature regulation, it does also contain protective substances for the skin. However, the question of sweat glands is not directly related to the preference for liquid foundation over mineral makeup.
