Self-tanning products are cosmetic items designed to give the skin a sun-kissed glow without the need for sun exposure. They typically contain active ingredients like dihydroxyacetone (DHA), which reacts with the amino acids in the skin's surface to create a temporary tan. These products come in various forms, including lotions, sprays, and wipes, allowing users to choose their preferred application method. To achieve the best results, it's important to prepare the skin by exfoliating and moisturizing before applying self-tanner. This helps ensure an even application and prolongs the tan's lifespan. Users should also follow the product's instructions for optimal results and to avoid streaks or uneven coloring.
