What is the primary function of an "accelerator" in tanning products?

The primary function of an "accelerator" in tanning products is to speed up the tanning process by enhancing melanin production. Accelerators are specifically designed to stimulate the skin's natural tanning mechanism, leading to a deeper and faster tan. They typically contain ingredients that promote melanin production, which is crucial because melanin is the pigment responsible for skin color and helps protect the skin from UV damage.

While hydration, fragrances, and irritation-minimizing properties are important aspects of tanning products, they do not define the specific role of accelerators. The focus on enhancing melanin production is what sets accelerators apart, making them essential for those looking to achieve a quicker and more effective tanning result.
