As the global sunscreen market continues to grow—valued at $13.4 billion in 2023 and projected to expand at a 6.4% CAGR—it becomes increasingly important to address the unsustainable practices surrounding the ingredients, packaging, and environmental consequences of these products.

The sunscreen industry’s success in improving skin protection should be matched by efforts to mitigate its broader effects on human health, the environment, and the circular economy. In this section, we explore the current sustainability challenges of sunscreens, the emerging alternatives, and the opportunity for a market shift toward greener, safer products.

Here is the chart illustrating the global sunscreen market cap growth from 2015 to 2023. The market cap has steadily increased from approximately $7.8 billion in 2015 to $13.4 billion in 2023, highlighting the significant expansion of the industry. This growth indicates a rising demand for sunscreen products, even as the market begins to shift towards more sustainable and eco-friendly alternatives.

The Environmental Impact of Sunscreens

Sunscreens contain chemical ingredients like oxybenzone, avobenzone, and octinoxate, which have been shown to harm marine life, especially coral reefs. The sunscreen industry’s use of synthetic chemicals and non-recyclable packaging exacerbates environmental degradation, making it a significant contributor to ocean pollution and landfills.

Key Environmental Challenges

• Coral Bleaching and Reef Damage: Ingredients like oxybenzone and octinoxate have been identified as major contributors to coral bleaching. Studies show that these chemicals can trigger coral mortality, inhibit coral growth, and cause irreversible damage to ecosystems.
  • Over 14,000 tons of sunscreen enter coral reef ecosystems annually, posing a direct threat to biodiversity (source: World Health Organization).
  • 10% of the world’s coral reefs are endangered due to the presence of harmful sunscreen chemicals (source: National Park Service).
• Water Pollution: Sunscreens are washed off into the water during swimming or bathing, with their chemical compounds polluting rivers, lakes, and oceans. These chemicals accumulate in aquatic life, causing ecosystem imbalances and impacting the quality of water resources.
• Plastic Waste: Sunscreen packaging, predominantly made from plastic, contributes to global waste. Many sunscreen bottles are non-recyclable or hard to reuse, adding to the growing global waste crisis.

Health Risks from Sunscreens

While sunscreens provide vital protection against UV rays, certain chemical ingredients in conventional products have been linked to hormone disruption and skin irritation. The absorption of sunscreen ingredients into the skin has raised alarms about their potential to cause systemic health issues, especially when used repeatedly.

Key Health Concerns

• Hormone Disruption: Chemicals like oxybenzone can interfere with hormone levels, leading to adverse reproductive and developmental effects. Research has found that oxybenzone can enter the bloodstream and accumulate in urine, blood, and even breast milk (source: Environmental Working Group).
  • The FDA’s 2019 study found that sunscreen chemicals reach dangerous levels in the bloodstream after just one application (source: FDA).
  • Over 80% of sunscreens contain oxybenzone or other endocrine-disrupting chemicals, despite the growing body of evidence pointing to their harmful effects.
• Skin Sensitivity: Sunscreens containing synthetic fragrances, parabens, and other artificial chemicals can cause skin irritation, allergic reactions, or exacerbate existing skin conditions, particularly for those with sensitive skin or preexisting dermatological conditions.
• Nanoparticle Risks: Some sunscreens contain nanoparticles of zinc oxide or titanium dioxide, which can penetrate deeper layers of the skin. The long-term effects of these nanoparticles on human health are not fully understood, and they may have unanticipated consequences on skin health.

Here is a chart displaying the market share distribution of conventional sunscreens versus reef-safe and mineral sunscreens in 2023. The blue dashed line shows the projected growth rate for both segments, with reef-safe and mineral sunscreens expected to grow significantly faster, at a rate of 15% CAGR compared to 4% CAGR for conventional sunscreens. This highlights the rising consumer demand for sustainable alternatives and the market opportunity for greener products.

Why People Still Use Sunscreens

Despite the growing evidence of their environmental and health impacts, sunscreens continue to be a widely used product, driven by various factors:

1. Health and Beauty Industry Influence: The sunscreen market is bolstered by the health and beauty industry, which promotes sunscreens as essential tools for skincare, anti-aging, and UV protection. The industry, valued at $49.6 billion in 2023, continues to profit from public perceptions of sunscreen as a necessity (source: Statista).
2. Consumer Trust: Many consumers trust sunscreen products due to their extensive marketing and endorsements by dermatologists. As a result, consumers often overlook the potential dangers of chemicals in sunscreens.
3. Convenience and Affordability: Chemical sunscreens are easy to apply and readily available. This convenience, combined with relatively low prices, makes them an attractive option for the mass market, despite the hidden health and environmental consequences.
4. Lack of Awareness: There is still limited awareness regarding the environmental and health impacts of sunscreens, especially in developing countries. As such, demand for eco-friendly alternatives is not yet widespread.
