"Bea Skin Care's Solar Defence SPF 50 (£28) not only protects hyperpigmented areas from darkening, but it also contains the treatment ingredient alpha arbutin, which helps to brighten the skin. Alpha arbutin and other brightening ingredients supress tyrosine, an enzyme that helps our bodies to produce melanin, so when you block this tyrosine pathway you'll be less reactive to UV wounds and trauma. A skincare regime with active ingredients like this will help to prevent melanin hyper-synthesis in the cells at the same time as treating excess melanin and offering UVA and UVB protection." — Bianca Estelle, medical aesthetician and Bea Skin Care founder
