MAC Lip Pencil Stripdown is a lip liner designed for shaping, lining, or filling in the lip. The product is available in a wide selection of colors that each work well with many different lipstick shades. The product packaging does not list the ingredients, but according to INCIDecoder, the ingredients include C10-18 Triglycerides, Talc, Hydrogenated Vegetable Oil, Caprylic/Capric Triglyceride, Synthetic Japan Wax, Tocopherol, Ascorbyl Palmitate, and Citric Acid. Positive aspects of the product include its smooth, creamy texture that is perfect for outlining lips or coloring them in. However, the product is not transfer-proof, so it needs to be reapplied after eating or drinking.
