Which of the following is a common sign of healthy skin?

An even texture is a common sign of healthy skin because it indicates that the skin is functioning properly and maintaining a balanced surface. Healthy skin typically has a uniform appearance without significant bumps, rough patches, or inconsistencies in texture. An even texture suggests that the skin is adequately hydrated, well-nourished, and has a good layer of natural oils that protect it. This smoothness not only enhances the aesthetic appeal of the skin but also reflects a balanced condition, free from excessive dryness or oiliness that can lead to other skin issues.

In contrast, dull appearance can indicate lack of moisture or other issues such as buildup of dead skin cells, indicating that while the skin may need some attention, it does not reflect the overall health. Excess oil can suggest overactive sebaceous glands, which may lead to acne or other skin problems rather than indicating health. Redness can signal irritation, inflammation, or other underlying skin conditions that are not characteristics of healthy skin.
