When looking for a sunscreen with fewer chemicals, it is recommended to choose a product with a physical barrier such as zinc oxide or titanium dioxide. Opt for a sunscreen labeled "for sensitive skin" or for children, as they tend to have fewer potentially irritating ingredients. Brands like Ombrelle Kids and Anthelios are popular choices. Remember to apply sunscreen often and 30 minutes before sun exposure for optimal protection. If you need more specific recommendations, consult with your pharmacist for guidance on comparing different products.
