The two main types of dermal fillers are hyaluronic acid and hyperdilute biostimulators. While both treatments effectively reduce signs of aging, they work differently and have different effects. Hyaluronic acid is a naturally-occurring substance found in the human body. It binds to water molecules to keep the skin hydrated, smooth, and wrinkle-free. Hyaluronic acid is often used to fill fine lines and wrinkles, plump lips, and contour the face. The effects of hyaluronic acid are instant, but they typically last for six months or less. Hyperdilute bio stimulators are made from synthesized, purified proteins and peptides. They are injected into the skin to stimulate the body’s own production of collagen and elastin. Unlike hyaluronic acid, the effects of hyperdilute biostimulators are not instant. It typically takes several weeks for the treatment to take effect, and the results can last up to two years. In summary, hyaluronic acid and hyperdilute biostimulators are effective dermal fillers, but they work differently. Hyaluronic acid instantly fills wrinkles, while hyperdilute biostimulators take longer to take effect but can last longer. Ultimately, the best choice of filler depends on the individual’s needs and desired results.
