These highlighters are offered primarily in two formats: liquid glow enhancers and twist-up/highlighter sticks.
Stick options are small (around 0.25 ounces). Liquid highlighters come in several sizes, including about 0.33 fl oz and 1.06 fl oz, with some bottles up to 1.35 fl oz.
Shade offerings vary by line: some collections have small curated ranges (around 5–6 shades), while at least one liquid range is described as offering up to 15 flexible shades.
Coverage ranges from sheer to light/medium. Many liquid formulas are buildable, so you can layer for more intensity without feeling heavy.
They can be worn multiple ways: alone, under or over foundation, mixed into foundation, used as a base/primer, or applied to high points (cheekbones, brow bones, collarbones). Some formulas are marketed for both face and body use.
Descriptions target a wide range of skin types—dry and very dry, normal, combination, oily, sensitive, acne-prone, and mature skin. At least one liquid formula explicitly notes suitability for dry, oily, and combination skin.
Some formulations list hydrating ingredients such as glycerin and shea butter; at least one liquid highlighter is noted as containing 2% squalane.
Application is described as easy and blendable. Common applicators include cushion-tip wands and liquid wands with cushion applicators for liquid formulas, and twist-up highlighter sticks for on-the-go use.
