At new spa Jet Concepts, skincare is indeed rocket science. Their Jet Facial treatment uses the Jet-M machine developed by a Russian rocket scientist. Using supersonic pressure to deliver active nutrients into the outermost layer of the skin, this facial allegedly helps oxygenate and exfoliate skin, unclog pores and stimulate collagen growth for clean and bright skin. Start with the Jet PureHyal, which involves infused hyaluronic acid to make skin supple. $165 at #03-03 Wheelock Place, 501 Orchard Rd., 6733-7055.
