Fillers are used to hide unwanted wrinkles, folds, and depressions on the face, catering to the desire for a more youthful appearance. They improve the contours, furrows, and wrinkles associated with the aging process, and can also enhance features such as lips and cheekbones. Fillers focus on treating wrinkle lines, deep furrows like laugh lines, small lips, and acne scars. They are effective for contour depressions, fine or deep wrinkle lines, furrows, or acne scar pits, and can be beneficial in improving contours after rhinoplasty, lip enlargements, and other procedures.
