Self-tanners are sold in several formats, most commonly lotions, aerated or foam sprays, mousses, and clear gels.
Common scent options include fresh, coconut, and other tropical fragrances, and some products are offered unscented.
Express formulas are fast-drying and formulated to deliver rapid, darker color—sometimes showing results in as little as an hour—and may require rinsing after development. Gradual lotions are designed for daily use and build a natural-looking tan over multiple applications.
Times vary by formulation: express foams can show color in about 1 hour (some directions recommend leaving them on 2–3 hours for the darkest results). Gradual lotions build color over repeated daily applications and are often visible after 1–3 uses; some facial moisturizers report change in about a week.
Some clear gels and mousses in the set are described as transfer-resistant or rinse-free; product descriptions use terms like “transfer resistant,” “no rinse required,” or note zero transfer onto sheets or clothing.
