Verdict

A moisturising SPF50+ sunscreen with a creamy lotion texture and birch-derived ingredients. It is best for normal-to-dry skin and users who prefer a comfortable glow rather than a powdery matte finish.

Best for: A moisturising daily SPF with a glow finish
Less suitable for: Very oily skin seeking a matte sunscreen; anyone sensitive to the listed UV filters, birch-derived ingredients or niacinamide; use during heavy sport unless the exact UK pack is labelled water resistant.
