One of the most important factors in choosing a filler treatment is understanding how it works. Over time, our skin begins to lose naturally occurring components such as collagen, elastin, and hyaluronic acid (HA), leaving skin more prone to develop etched-in lines and wrinkles. BELOTERO BALANCE® is a hyaluronic acid (HA) injectable filler that completely integrates into the skin tissue. While some fillers are designed to rebuild facial volume and structure, BELOTERO BALANCE specifically treats moderate-to-severe etched-in lines and wrinkles such as vertical lip lines above and around the lips.
