Pros
- Genuinely gentle and well-studied, with the full formula on the label plus aloe and vitamin E in the base.
- Decent staying power for a milder active, roughly 4 to 8 hours against mosquitoes.
Cons
- The sunscreen combo is the dealbreaker: the CDC says apply sunscreen and repellent separately, since sunscreen needs frequent reapplying and repellent doesn't.
- IR3535 is milder than DEET or picaridin, so you aren't getting top-tier protection either.
The full review
This SPF 30 pump pairs 19.6% IR3535 with four sunscreen actives, and its underlying pillars are excellent, with near-perfect safety, top-tier evidence, and high transparency for a fully accounted formula. It even earns credit for labeling reapplication honestly, roughly every 2 hours in line with its measured protection. Despite all that it remains not recommended, because combining repellent with sunscreen runs against CDC guidance to apply the two separately and forces you to overuse or underuse one active. IR3535 is gentler than DEET or picaridin, and while our model reads 4 to 8 hours on mosquitoes and 5 to 8 on ticks, the label's 8-hour mosquito claim describes reduced biting, not complete protection. It wears pleasantly, with aloe and vitamin E in the base, but the combo format is the dealbreaker.

Effectiveness45%96Mosquitoes: 4–8 h of complete protection. Ticks: 5–8 h of complete protection. Protection times are modeled from the actives, concentration, and format (see methodology). 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)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~14 h as repellency decays. IR3535's protection is species-variable: ~9–10 h against Aedes/Culex in the lab but only ~4 h against Anopheles (Thavara 2001), and it needed ~2× the DEET dose for equal protection (Costantini 2004). The Ghana 2025 ~9 h figure is percentage efficacy, not a measured complete-protection time. Hence the wide 4–8 h band.
Tick estimate basis (low confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~14 h as repellency decays. Buchel 2015 (EPA protocol): 10% IR3535 gave ~3.5-4 h against Ixodes, the weakest of the major actives. Higher figures (Carroll 2008/2010) come from uncontrolled trials, so concentrations above 15% are LOW confidence.

What the marketing says, versus what the evidence supports.
“DEET-free”
Deet FreeStrongAccurate; the repellent active is IR3535.
“Protects against gnats, no-seeums, sand flies, and biting midges”
EfficacyStrongListed pests on the EPA-accepted label (reapply after 6 hours).
“Provides SPF 30 sunscreen protection, very water resistant”
OtherModerateFDA OTC sunscreen claim with four labeled actives. CDC/EPA generally advise against combination repellent-sunscreen products because reapplication needs differ.
“IR3535 19.7%”
EfficacyStrongConfirmed by EPA registration data and the EPA-accepted label.
“8 hours of protection against mosquitoes”
DurationStrongConsistent with our complete-protection estimate (~8 h).
“Up to 10 hours of protection against deer ticks”
DurationStrongConsistent with our complete-protection estimate (~8 h).
