What substances can really reduce the mimic wrinkles, most commonly appearing on the upper third of the face (forehead, brow and eye area)? Today it is neuromodulatory peptides.
The peptides used in cosmetology are small protein molecules able to penetrate the skin’s protective barrier. Peptides can have a wide range of effects on the skin structures, the neuromodulatory ones block the impulse transmission from the nerve fibre to the muscle.
Botulinum toxin works in the same general way: it blocks the transfer of the signal towards a facial muscle, stopping it from contracting which makes the wrinkles disappear.
