The Science Behind Our Daily SPF 50+: Safe, Effective & Clinically Approved

At By Sarah, we understand that choosing the right skincare products can be overwhelming, particularly when it comes to sun protection. That’s why we spent two years developing our By Sarah Daily SPF 50+, ensuring that it is both safe and effective for everyday use. We are committed to transparency, scientific integrity, and the highest regulatory standards, so you can feel confident in your skincare choices.

Addressing Misinformation: Why You Shouldn't Rely on Yuka

Not all information sources about cosmetic ingredients are based on sound science. We understand that third-party rating apps like Yuka can cause confusion when it comes to ingredient safety. It's important to highlight that Yuka is not science-based. The app does not cite or reference its sources, does not consider dosage or testing methods, and lacks the expertise to properly interpret scientific findings. Furthermore, Yuka heavily relies on animal data, which is not a reliable predictor for human skin safety due to differences in skin permeability and metabolic systems. Misleading information like this can create unnecessary fear around ingredients that are thoroughly tested and regulated under stringent safety guidelines. We encourage consumers to seek reputable sources for cosmetic safety, such as the CTPA’s consumer information website, which provides accurate, science-backed insights into ingredient exposure and safety.

A Science-Backed Approach to Safety and Efficacy

In the UK and EU, cosmetic formulations must comply with SCHEDULE 34 of the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019. These regulations are informed by the Scientific Committee on Consumer Safety (SCCS), an independent advisory body of the European Commission. The SCCS provides authoritative recommendations based on rigorous scientific analysis and ensures that all guidelines are conservative enough to account for cumulative exposure from multiple skincare products.

At By Sarah, we embrace these rigorous standards and go beyond regulatory requirements by integrating the latest dermatological research into our formulations. Our commitment to safety and effectiveness means that each product is tested extensively before it reaches your skin.

Understanding Ingredients and Safety Standards

It’s important to remember that both natural and synthetic ingredients can cause allergies or sensitivities – the key factor is the dosage. Our formulations are meticulously crafted following stringent European safety regulations, which are among the most rigorous in the world. Every ingredient in Daily SPF 50+ has been independently assessed and approved by regulatory bodies, ensuring compliance with the highest safety standards.

We also ensure that our products are free from unnecessary additives, such as artificial fragrances, parabens, and silicones, making them suitable for even the most sensitive skin types. Our dedication to ingredient transparency means that you always know exactly what you're applying to your skin and why it has been chosen.

What Makes By Sarah Daily SPF 50+ Different?

We take an uncompromising approach to research and clinical testing before launching a new product. Our Daily SPF 50+ has undergone extensive testing and verification to guarantee its effectiveness and suitability for all skin types, including sensitive skin. Here’s why you can trust it:

Dermatologically Approved: Independent, third-party controlled clinical studies confirmed that our Daily SPF 50+ meets the highest classification for skin compatibility and is suitable for sensitive skin.
Trusted Ingredients: Each formula is developed in collaboration with experienced chemists, pharmacologists, and dermatologists. We conduct independent third-party laboratory testing to ensure regulatory compliance and ingredient safety.
Responsible UV Protection: We have carefully selected our UV filters to prioritise both skin safety and environmental impact. That means we do not use benzophenones, camphor derivatives, or cinnamate derivatives –ingredients currently under review for potential health and environmental concerns.
Sustainability Commitment: At By Sarah, we are dedicated to sustainable practices, ensuring that our packaging is recyclable and our formulations are as kind to the environment as they are to your skin.
