Pros
- Controlled-release tech stretches just 20% DEET to a labeled 10 hours, less active for more time.
- A lotion that rubs in and feels lighter and lower-odor than a high-DEET spray.
Cons
- Tick cover is shorter at 3 to 4 hours, and it's still DEET, so keep it off plastics.
The full review
This controlled-release lotion takes a smart approach to 20% DEET, using sub-micron encapsulation to slow the release and stretch coverage, and it earns a recommended in our maximum protection tier. The EPA-registered label backs up to 11 hours, with our model landing at 10 hours of complete mosquito protection, though tick coverage is more modest at 3 to 4 hours. Evidence and safety are both strong, and all 7 audited claims hold up, though the split skews moderate (3 strong, 4 moderate), reflecting some softer marketing language. Because the protection figure comes from the registered label, it is well grounded, and the lotion feels lighter and lower-odor than a high-DEET spray. Transparency is the usual limiter, with the inert ingredients undisclosed.

Effectiveness45%95Mosquitoes: 10 h of complete protection. Ticks: 3–4 h of complete protection. Protection times come from the product's EPA-registered label (a manufacturer maximum, capped to a defensible ceiling). Scored on a saturating curve (each added hour counts less than the last), 65% mosquito / 35% tick, with reasonable confidence.

How long it protects
Complete protection ends when the first bite gets through; partial protection keeps reducing bites as repellency decays. EPA label times are verified; the rest are modeled from the actives, concentration, and format.
Mosquito estimate basis (moderate confidence)
From the product's EPA-registered label (manufacturer maximum against mosquitos, treated as an upper bound). The label's "up to 11 h" is a maximum; we cap it at 10 h for this active class as a defensible complete-protection estimate. Partial protection (reduced but real bite suppression) is modeled to extend to ~18 h as repellency decays.
Tick estimate basis (moderate confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this lotion (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~7 h as repellency decays.

Claims audit
What the marketing says, versus what the evidence supports.
“Sweat resistant”
OtherModerateA wear/performance attribute, not an efficacy claim; plausible but not independently verified.
“Family-friendly formula”
Kid SafeModerateReduced-absorption 20% DEET lotion positioning; standard DEET child-application precautions still apply per label.
“Odorless, non-greasy, alcohol-free; compatible with sunscreen”
OtherModerateCosmetic/compatibility claims from the manufacturer.
“Controlled-release encapsulation reduces DEET absorption by 67% per application”
SafetyModerateManufacturer claim based on its patented sub-micron encapsulation technology; plausible mechanism but the specific figure is not independently verified.
“Effective against ticks and all mosquitoes”
EfficacyStrongDEET at 20% is fully dosed with a ~10 h mosquito / 3–4 h tick complete-protection estimate, so a direct 'effective against ticks and mosquitoes' claim is well-supported.
“DEET 20%”
EfficacyStrongActive ingredient concentration confirmed by EPA registration.
“Up to 11 hours of protection against mosquitoes”
DurationStrongEPA label-approved protection time, confirmed in the EPA repellent search tool.
How to apply it
Squeeze the lotion into your hands and apply a thin, even layer to all exposed skin, avoiding eyes and lips; wash hands after applying. Do not apply to children's hands; when using on children, apply to your own hands first and then spread on the child. Reapply after about 11 hours or after swimming, heavy sweating, or toweling off, and wash treated skin with soap and water after returning indoors.
