There are some amino acids our bodies can’t produce no matter how critical they may be. Fortunately, Natura Bissé has packed a hearty supply into Essential Shock Intense, its newly reformulated line of skin treatments hitting Neiman Marcus this month. Essential Shock has long featured these building blocks of collagen and elastin. The Intense-ified edition also boasts a proteoglycan complex to promote firmness and elasticity and even more amino acids for hydration and luminosity — a total of 20 active ingredients. Natura Bissé has mixed a moisturizing cream, gel cream for oily skin, nourishing pineapple masque, a lip and eye balm with SPF 15 and the hero serum: Essential Shock Intense Complex. Massage some on, and get that firming feeling.
