What is a tanning “booster” designed to enhance in the skin?

A tanning "booster" is specifically designed to enhance melanin production in the skin. Melanin is the pigment responsible for the color of your skin, and increasing its production can lead to a deeper and longer-lasting tan. Tanning boosters typically contain ingredients such as tyrosine or other amino acids that stimulate the production of melanin when exposed to UV light, facilitating a more effective tanning process.

On the other hand, products that protect against UV rays are formulated with SPF technology to prevent skin damage from sun exposure. Moisturizers focus on hydrating the skin to maintain its health, and scented products may enhance the tanning experience but do not contribute to the tanning process itself. Therefore, the most appropriate choice in the context of enhancing the skin's tanning capabilities is a product that boosts melanin production.
