Botox is a neurotoxin. These substances target the nervous system, disrupting the nerve signaling processes that stimulate muscle contraction. This is how the drug causes temporary muscle paralysis.
In order for any muscle to contract, the nerves release a chemical messenger called acetylcholine at the junction where nerve endings meet muscle cells. Acetylcholine attaches to receptors on the muscle cells and causes the cells to contract, or shorten.
Botox injections prevent the release of acetylcholine, which stops the muscle cells from contracting. In this way, the toxin helps the muscles to become less stiff.
Injectable hyaluronic acid (HA) is a type of temporary dermal filler. Hyaluronic acid is found naturally through out the body, with the highest concentrations in the joints, eyes, and skin. In the skin hyaluronic acid attracts water, which allows the skin to become more hydrated. As we age, the fat, muscles, bone, and skin in our face begins to thin. This loss of volume leads to either a sunken or sagging appearance of the face, fine lines, wrinkles, folds, and thin lips. Injectable HA is used to reduce the appearance of fine lines and wrinkles, facial folds, and to create structure, framework, and volume to the face and lips. The effects of injectable hyaluronic acid are seen immediately.
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
