Wrinkles are formed by contraction of facial muscle. You'll have wrinkle around your eyes when you laugh or smile, you'll have wrinkles betweent your eyebrows when you rown, they come along with common facial expressions. There are individual differences in the appearance of wrinkles. In addition, as we age, our skin loses its elasticity and firmness, and if we continue to make facial expressions over the years, wrinkles can become more obvious. It is common to see wrinkles between the eyebrows or well-defined lines on the forehead without even noticing.
For those whose muscle of lower jaw has a strong contraction power, botox injection is very effective in sharpening the chin.

Masseter Botox requires larger doses of Botox and deeper injections to reach the masseter muscles. This treatment ultimately results in the relaxation of overactive jaw muscles. This leads to a slimmer and more angular facial structure.
The term “gummy smile” also referred to as excessive gingival display, refers to when someone smiles and there is too much gum tissue showing above the top teeth. A small Botox injection at both sides of the nostril and nose to mouth lines helps to weaken the muscles response and make gingival diplay smaller.

Botulinum injections block acetylcholine receptors in the sebaceous glands, thereby reducing sweat and sebum secretion, which also shrinks pore size, resulting in tighter pores and firmer skin.

Sweating is caused by acetylcholine, a neurotransmitter released by the brain as a result of changes in body temperature regulation, tension, and stress, which stimulates the eccrine glands, one of the sweat glands. Botulinum injections can inhibit sweating by suppressing the transmission of acetylcholine.Botulinum injections can reduce sweating in the armpits, palms, and soles of the feet.
