About this sunscreen
Bybi Day Defence SPF 30 Moisturiser is a pure mineral sunscreen using Zinc Oxide as its only UV filter, so it sits in the chemical-free camp. It has a balanced finish but carries a medium white cast and a slightly heavier feel typical of zinc-based moisturisers. It does not sting and has low pore-clogging concern, and it works okay as a makeup base. With moderate protection at SPF 30 and a score of 70.0/100, it is a reasonable everyday mineral pick rather than a high-protection choice.
