MAYDAY is our most borrowed after-sun product. If you’re heading on a group trip somewhere with intense UV and zero shade, maybe bring 2 just in case one goes "missing".

The Problem

SOS, you've overdone it. You got burned.

Maybe you put on SPF. Maybe not. Either way, you got fried. Getting a bad sunburn is only part of the problem. UV overexposure triggers cellular stress that breaks down your skin barrier, accelerates chronic inflammation, and compounds sun damage over time. That's inflammaging. And without intensive recovery, your skin is still breaking down long after the burn fades.

More than aloe. The most advanced sunburn recovery. Safe for face and body

Our Solution

More than aloe. The most advanced sunburn recovery.

Powered by 3X Sirenas Complex AQ, MAYDAY rapidly calms burns, redness, irritation, and swelling while helping minimize peeling.
Accelerates Sunburn and Windburn Recovery
Quickly soothes severe redness, irritation, swelling, and inflammation — fast.
Minimizes Peeling and Restores Damaged Skin Cells
Accelerates skin’s natural healing mechanisms, rebuilding damaged cells before peeling starts.
Strengthens Skin Barrier at the Cellular Level
Acute UV overexposure triggers intense inflammation that breaks down barrier from within. MAYDAY works beneath the surface to neutralize inflammaging and restore what extreme UV exposure strips away.
Lightweight, Non-Sticky, Fragrance-Free
Clear, not neon green. Feels like putting out a fire, without the messy aftermath.

How it works

Sunburn relief in hours.

  • Hours 0-6

    Cool the Heat for Immediate Relief

    A cooling gel-cream helps take the edge off hot, overexposed skin while a 3X boost of Sirenas Complex helps reduce visible redness, swelling, and inflammation and replenishes moisture-loss.

  • Hours 6-24

    Stay Ahead of the Burn

    Redness and sensitivity often peak between 12 and 24 hours after sun exposure. MAYDAY helps aggravated skin by moisturizing, supporting the skin barrier and calming the inflammaging cascade through the most acute post-sun exposure window.

  • Hours 24-48

    Support Cellular Recovery and Minimize Peeling

    In UV-stressed skin cells, Sirenas Complex helps calm key inflammatory signals after 48 hours, supporting your skin's natural cellular repair mechanisms.

  • Hours 48+

    Reinforce Skin Barrier Defense

    As overexposed skin can become dry, tight, or flaky, keep using MAYDAY to help restore comfort and support barrier resilience.

How to use: Shake well. Apply a generous layer to clean, affected skin after sun or wind exposure. Reapply every 2-3 hours for best results.

Pro tip: After 2–4 days of using MAYDAY, switch to TERNS EVERYDAY to help keep recovery going strong after the burn fades.

*Based on published ingredient studies and in vitro testing of Sirenas Complex in UV-stressed human skin cells. Individual results vary.
