Covalent Daily Defense SPF 50
Sheer mineral sunscreen, zinc 18%
An 18% zinc-oxide mineral screen milled fine enough to disappear on most skin tones, with a silky dry-touch finish that behaves under makeup. Iron-oxide pigments add meaningful visible-light defense for melasma-prone and post-procedure skin.
This is the sunscreen your treatment plan assumes you are wearing. Every retinoid night and every peel appointment is an investment SPF 50 protects.
- 18% non-nano zinc oxide + iron oxides
- Sheer universal tint, dry-touch silicone-light base
- Water resistant 40 minutes
- 50 mL tube; reapply every two hours in sun

Good, wish it were bigger
The formula is excellent and I have no complaints about how it wears. At this size and a proper daily amount it disappears quickly.

Kids will wear it too
No stinging and no fight about the white cast, which means it actually gets used. I bought a second for the car.

Great finish, watch the eyes
Beautiful satin finish and no pilling. It does migrate slightly if I sweat heavily, so I keep it away from my lower lids.

Wears well all day
Still there at six in the evening without a greasy slick, and it has not broken me out once in two months of daily use.
