What does "lipophilic" mean?

  1. Substances with a pH above 7.0

  2. Water-loving

  3. Oil-loving

  4. Substances with a pH below 7.0

The correct answer is: Substances with a pH above 7.0

"Lipophilic" means oil-loving. In the context of skincare and esthetics, lipophilic substances are attracted to oil and oil-based substances rather than water. This property is important to understand when selecting products for different skin types and conditions. Option A, substances with a pH above 7.0, does not accurately define lipophilic. Option B, water-loving, is the opposite of lipophilic. Option D, substances with a pH below 7.0, is not related to the concept of lipophilic.
