There is no single "best" homemade sunscreen. Making sunscreen at home is not recommended as it is difficult to create a formula that offers adequate and consistent sun protection. Homemade sunscreens lack the rigorous testing and regulatory oversight that commercial sunscreens undergo, making them potentially ineffective and even harmful to your skin.
Here's why:
- Sun Protection Factor (SPF) is complex: Achieving a desired SPF requires precise ratios of active ingredients like zinc oxide or titanium dioxide. Homemade recipes often lack the accuracy and scientific testing needed to guarantee effective SPF.
- Stability and Shelf Life: Homemade sunscreens are susceptible to bacterial contamination and degradation over time. They may not be stable enough for long-term use, potentially losing their effectiveness.
- Ingredients: The quality and purity of ingredients in homemade recipes can vary, and some ingredients may be irritating or even harmful to your skin.
It's important to prioritize your skin health and safety. Instead of relying on homemade solutions, choose a commercially available sunscreen that has been rigorously tested and approved by the FDA.
Always look for a sunscreen with:
- Broad spectrum protection (protects against both UVA and UVB rays)
- SPF 30 or higher
- Water resistance if you will be swimming or sweating
- Ingredients that are safe for your skin type
Remember, the most effective way to protect yourself from the sun is to:
- Seek shade during peak hours (10 am to 4 pm)
- Wear protective clothing, including a hat and sunglasses
- Apply sunscreen liberally and reapply every two hours, or more often if swimming or sweating
