As a natural alternate to injections, this smoothing serum has scientifically tested active ingredients that smooth facial lines and wrinkles. The Zk’in’s Line Smoothing Serum’s main active ingredient (Paracress extract) briefly blocks the muscular contractions that adds to those expression lines. The Gatuline Expression is a strong active ingredient that works just like injectables but is totally safe, gentle and pain free, bringing fast visible smooth skin results. Not like chemical based eye creams that can lead to milia (white little spots beneath the eye) or aggravate puffiness, this gel based is quickly absorbed by the skin that makes it perfect for all types of skin. Zk’in organic skincare loves your skin, so all their products contain no parabens, sulphates, petrochemicals, animal products and no artificial ingredients.
