Freckles are small, concentrated spots of melanin on the skin, most visible on fair complexions. They’re a genetic trait linked to the MC1R gene and are found in people worldwide.
Global Distribution
- Worldwide Estimate – Around 1.5 billion people have freckles worldwide
- High Prevalence in the Philippines – About 75% of Filipinos have freckles
- Variation Among Populations – Freckle prevalence differs greatly among ethnic groups
- Common in Redheads – Freckles are most common in redheads, who make up 4 to 5% of the world’s population
Genetic and Environmental Factors
- Genetics – Freckles are linked to specific variants of the MC1R gene
- Sun Exposure – UV radiation stimulates melanin production, making freckles darker and more visible
Age and Development
- Age of Onset – Freckles usually appear around age two or three and are more common in children before puberty
- Fading with Age – Freckles may fade in winter or with age
Cultural and Fashion Trends
Freckles are becoming increasingly trendy, particularly with the rise of social media and freckle-celebrating content.
Though it’s hard to get an exact percentage, roughly ten to 15% of the world’s population may have freckles. This common genetic trait results from a complex interplay between genes and the environment.
