About this sunscreen
Kailon Sun Shield is an SPF 40 mineral sunscreen filtered entirely with Zinc Oxide, so it suits those who prefer a single-ingredient mineral formula. The balanced finish leans a bit heavier on skin and can leave a moderate white cast, common with pure-mineral formulas, but it does not sting the eyes. Pore-clogging risk reads as low and it works acceptably under makeup. Scoring 70/100 with moderate protection, it is a basic mineral option.
