Synthetic sources of dermal fillers include hyaluronic acid and which of the following?

Synthetic sources of dermal fillers primarily include substances that are used to enhance volume and hydration in the skin. Hyaluronic acid is one of the most common naturally occurring substances used for this purpose due to its ability to hold moisture and provide a plumping effect. Silicone, as a synthetic option, is also utilized in certain types of dermal fillers because of its ability to create a smooth texture and provide long-lasting results when injected into the skin.

Silicone-based fillers can provide a more permanent solution compared to others, making them appealing in certain cosmetic procedures. The properties of silicone allow it to integrate into the tissue, but it must be used carefully by trained professionals to minimize risks.

Other options, such as collagen, glycolic acid, and vitamin E, are either natural substances or used in different contexts. Collagen fillers are derived from natural sources, while glycolic acid is primarily used as an exfoliant in chemical peels. Vitamin E is beneficial for skin health, often applied topically rather than injected, which sets it apart from synthetic filler options. Therefore, silicone is recognized clearly as a synthetic source of dermal filler.
