Hourglass Icon is a very cool-toned, medium-dark red with a natural finish. It is a permanent lipstick that retails for $32.00 and contains 0.08 oz.
Hourglass Icon GIRL Lip Stylo ($32.00 for 0.09 oz.) is a bold, medium-dark red with cool, pink undertones and a natural sheen. It had semi-opaque, buildable color coverage that applied evenly and smoothly. It had a creamy, thin (but not too thin!) texture that glided across the lips nicely but didn't melt too much that it was hard to be precise. The soft sheen and creamier consistency made it appear almost like a lip stain. The color lasted for five hours, was hydrating, and very comfortable to wear.
The GIRL Lip Stylo formula is supposed to have "modern color with luxurious hydration for a lustrous finish," while the brand founder is quoted (on Sephora) stating, "I can build as much--or as little--color as I like." I would describe the coverage semi-opaque and buildable, which seemed to fit the brand's description. The consistency was smooth, creamy, and lightweight, but the color still adhered well to the lips (three to five hours, depending on the shade). I definitely felt like I could apply a little here, a little there, and then spread the color out by pressing my lips together for sheerer coverage, or I could apply a single layer and get semi-opaque coverage fairly easily. The formula was incredibly comfortable to wear: lightweight, hydrating, and smoothing. Some balm-like formulas that have more coverage can sit in lip lines, but I felt like these filled them and made them look softer. I didn't notice any scent or taste.

Precision color meets luxurious hydration. GIRL Lip Stylo features the color intensity of a lipstick fused with a luxurious blend of shea butter, jojoba, mimosa and sunflower seed for softer, fuller lips. The silky formula glides across lips for a second-skin feel with a lustrous finish.
