Final answer:
Adore Cosmetics increased the SPF value of sunscreen lotions in the Middle East due to climatic requirements, providing better protection against the region's high UV radiation levels.
Step-by-step explanation:
Adore Cosmetics' decision to increase the SPF value of their sunscreen lotions for the Middle Eastern market is predominantly due to climatic requirements. The intense sunlight and high UV radiation levels common in this region necessitate a greater level of protection to prevent skin damage. As Figure 21.6.4 Chemistry of Sunscreen indicates, sunscreens with higher SPF values offer better protection from UVB rays, although the increase in protection is marginal past an SPF of 30. Nonetheless, given the extreme UV exposure in the Middle East, the adaptation satisfies the demand for more effective UVB protection. An adapted product also potentially caters to different skin pigmentation in this demographic, as those with lighter skin may require higher SPF products to counteract the reduced natural melanin protection from UV radiation.
