Dermal fillers are injectable gels composed of hyaluronic acid, naturally found in the skin, which helps diminish facial lines and restore lost volume. Aging and exposure to environmental stressors contribute to facial volume loss. Dermal fillers work by replenishing this lost volume, effectively plumping thin lips, enhancing shallow contours, softening facial creases and wrinkles, improving the appearance of scars, and reconstructing contour deformities while maintaining a natural look.
