Which ingredient is typically NOT found in high-quality tanning products?

High-quality tanning products are formulated to provide the best possible experience and results while minimizing potential skin irritation or adverse effects. Parabens, which are synthetic preservatives used in many cosmetics and skincare products, are commonly avoided in products labeled as "high-quality." The concern surrounding parabens stems from their potential to disrupt hormonal balance, leading to anxiety among consumers about their safety.

In contrast, high-quality tanning products often incorporate natural oils to nourish and hydrate the skin, ensuring a smooth application and enhancing the tanning effect. Additionally, vitamins are commonly included to promote skin health, while Erythrulose serves as a sunless tanning agent that provides a gradual, natural-looking tan. Therefore, the inclusion of natural oils, vitamins, and Erythrulose aligns with the standards of high-quality tanning products, whereas parabens do not.
