About this formula
Mineral-only SPF 30 with no chemical UV filters — specifically formulated for skin that reacts to oxybenzone, avobenzone, and octinoxate. 18% zinc oxide, suspended in a lightweight serum base. Refill pouch — fits the Starter Kit aluminum vessel.
Full ingredient list: Aqua, Zinc Oxide 18%, Dimethicone, Glycerin, Caprylic/Capric Triglyceride.
Why each ingredient is here: Zinc Oxide is the only UV filter that is both broad-spectrum (UVA + UVB) and rated non-irritating for reactive skin by FDA; Dimethicone prevents the white-cast tackiness typical of high-zinc formulas; Caprylic/Capric Triglyceride (fractionated coconut oil — Malassezia-safe fraction only) carries the zinc uniformly without occlusion.
What people say
"Chemical SPF gives me contact dermatitis. Every mineral SPF I've tried leaves a white cast so bad I stop using it. The Derrin serum is the first one that goes on without looking like sunblock paint — and it's only five ingredients, so I know exactly why it doesn't irritate."A.L., sensitive skin panel
