When using both products together, always apply sunscreen first, followed by insect repellent.
- Sunscreen should go directly on clean, dry skin so it can form an even, protective layer.
- Insect repellent goes on last, over your sunscreen, to create a barrier that keeps mosquitoes and ticks away.
- Reapply sunscreen more often (about every two hours, and after swimming or sweating), but you usually do not need to reapply insect repellent more than once per day unless the product label tells you otherwise.
The same routine applies when you use plant-based repellents, such as oil of lemon eucalyptus (OLE). Apply sunscreen, let it absorb fully, then add a thin, even layer of OLE repellent on top.
