Which of the following best describes restorative embalming?

Restorative embalming is specifically focused on enhancing the deceased's appearance, which is particularly important for open-casket viewings. This type of embalming involves not just the preservation of the body but also techniques to restore a natural look by addressing features such as facial contours, skin tone, and overall presentation. This process may include using various cosmetic products, waxes, and other restorative techniques to create a lifelike appearance that can provide comfort to grieving families and friends during the viewing.

The other options do not align with the definition of restorative embalming. Immediate burial refers to a practice without extensive embalming, while using preservatives alone would not address the aesthetic aspects. Embalming performed at the time of death does not specifically imply the use of restorative techniques aimed at enhancing appearance, but rather encompasses the general practice of embalming. Therefore, emphasizing the aspect of appearance enhancement aligns perfectly with what restorative embalming entails.
