In this final step of our exploration of sun care products in preparation for the Rencontres by SFC in June, we take a close look at the efficacy tests accompanying these products.

The objective is to ensure complete protection against UVA and UVB, while providing a stable formula, pleasant sensory properties, safeguarding consumer health, minimising environmental impact, and keeping costs under control. On top of this, new developments are becoming increasingly innovative: waterless formats, sticks, sweat-resistant formulas, products for hair, and more… a real nightmare for formulators! What choices do they have today?
