Botox and fillers are both non-surgical treatments used to for facial rejuvenation and to minimise signs of aging. However, they are chemically entirely different and therefore, so is their mechanism of action. The indications for their use varies and only a trained cosmetic surgeon would know when to use these products to maximise their benefit.
Botox (Botulinum toxin) is a neurotoxic protein and is produced by a bacterium Clostridium botulinum and other related species. As a neurotoxin, botox when injected, paralyses the muscles in the area. Wrinkles and fine lines on the face are exaggerated by muscle contraction with facial expressions, like between brows, forehead and around the eye area. When these muscles are paralysed with botox injection, they relax, thus ironing out the lines and wrinkles making the area look smooth. The effect lasts for four to six months and regular treatments may be needed to maintain the results.
Fillers used for for the face are usually composed of hyaluronic acid, calcium hydroxyapatite or collagen. They smooth out skin folds and lines by adding volume to the injected area. They are used to improve wrinkles on the forehead, brow area, the area around the eyes and neck. The results may last for six months to up to two years, depending on the type of filler used. These days, fat transfer is being used as a very effective filler.
