If you can afford the popular NV Perricone skincare products, they can be found at Joyce Boutiques. The range - founded by Nicholas Perricone - contains neuropeptides - tiny strings of amino acids found naturally in the body. Perricone says they're necessary for cells to function, because it's through them that the brain is able to signal and control the thymus (the master gland of the immune system), which instructs cells to behave in certain ways.
The Neuropeptide Facial Contour ($2,500 for 2.5oz) is designed to rejuvenate dormant skin cells, the brand says. If you really want to splash out, there's the Neuropeptide Facial Conformer ($5,800 for 2oz) - described as a transdermal serum containing a potent concentration of 41 targeted neuropeptides designed to penetrate deeply into the skin to improve tone and texture and decrease the appearance of fine lines and wrinkles. A Facial Serum Prep ($1,750 for 6oz) is also available.
