National UV and Sunscreen Response Survey
Globally, UV radiation is becoming increasingly stronger due to environmental changes. In this context, examining how well individuals in each country respond to UV exposure is very meaningful. UV radiation can cause skin aging and skin cancer, making it directly related to public health. In this article, we will briefly investigate the UV index, per capita income, and per capita sunscreen expenditure of each country to assess their UV response capabilities. Countries with higher UV response capabilities will likely be “younger-looking” and “healthier” in the future.
Here, we will calculate an index called the “SBRindex” (Sunscreen Response Index). The lower the SBRindex value, the better a country is at responding to UV radiation.
The Importance of Ultraviolet (UV) Response
The more exposure to ultraviolet (UV) radiation, the greater the impact on the skin. UV rays can damage skin cells, causing wrinkles, dark spots, and blemishes, and in severe cases, may even lead to skin cancer. Therefore, using sunblock is an essential method to protect skin health. To improve UV response, economic conditions, sunblock usage habits, and education are necessary.
Criteria and Methodology
The “SunBlock Response index (SBRindex)” is a hypothesis set forth by the research team at Happiness and Technology Co., Ltd., based on the following three indicators. While some estimated data are included, which may not be entirely accurate, we believe this provides significant insights into preparedness for changes in the global environment. Using sunblock purchases as a criterion is meaningful in assessing individual readiness. The following types of data were used in this survey:
① UV Index: Indicates how much a country is exposed to ultraviolet radiation.
② Sunblock Expenditure per Capita: Shows how much individuals in each country invest in sunblock. (2023, $)
③ Per Capita Income: Used to assess the economic conditions that influence the purchase and use of sunblock. (2023, $)
Index Calculation Model
SBRindex = (①UV Index) / (②Sunblock expenditure per capita / ③per capita income) / 1,000
The model is designed so that a higher per capita income results in a lower index value. Therefore, a lower SBRindex value indicates higher UV resilience, meaning a better condition.
This model applies to the top 50 countries selected based on per capita income. These 50 countries fall within the top 25% of global per capita income, assuming they have the conditions necessary for a developed sunblock market.
What is the SBR Index Value by Country?
South Korea’s UV Index is 7. The UV Index has a total of 11 levels. The estimated annual per capita sunscreen purchase for South Koreans is $6.77, and the per capita income is $31,900. Therefore, the SBR Index value is 33, which ranks 16th out of 50 countries. The lower the SBR Index value, the better. The top-ranked country is Iceland with a score of 9, followed by Canada with 14. The UK ranks 11th with 29, Vietnam 37th with 77, China 48th with 190, and Nigeria 50th with 344.
The SBR Index model favors countries with higher income levels, as they tend to be located at mid-latitudes with lower UV Index levels. However, there are some unexpected cases. For example, the United States ranks 35th with a score of 75, and Greece ranks 38th with 78. These countries have the conditions to adequately respond to UV exposure, yet cultural characteristics or differences in social health education may play a role.
While the exact data could slightly alter these results, the general trend would likely remain the same. Additionally, the average SBR Index value for the 50 countries is 67, indicating a low level of UV protection through sunscreen usage. In a rapidly changing global environment, an SBR Index value of around 30-50 would be necessary to ensure a country is safe from UV radiation and its citizens are healthy.
For sunscreen manufacturers, this represents a significant opportunity to expand into new markets. In the next installment, we will develop the “Sunscreen Market Attractiveness Index” by country. This index will indicate which countries present attractive opportunities for sunscreen market development and emphasize the importance of early sunscreen use for maintaining competitive health standards.
