We’ve previously covered essential medicines for Bali travel, including pain relief patches, stomach remedies, and cold medications.

Quick tip: Should you apply sunscreen or insect repellent first? The correct order is sunscreen first, then insect repellent. Here’s why: Sunscreen should go on first because it needs to form an even protective layer on your skin to effectively block UV rays. It’s best applied 15–30 minutes before heading out, giving it time to absorb. Insect repellent comes second, as its active ingredients (like DEET or other repellents) need to evaporate into the air to work. If you apply repellent first, sunscreen can dilute or cover it, reducing its effectiveness. Pro tip: After applying sunscreen, wait a few minutes for it to absorb, then apply repellent. Ideally, leave a 5–10 minute gap between the two. Some products warn against mixing with sunscreen, so check the label. If you need to reapply sunscreen, remember to reapply repellent too. This way, both products work at their best—keeping you sun-safe and bug-free!
