When SkinSafe™ 58°F meets your skin, your body responds almost immediately. Blood vessels near the surface begin to narrow — a process called vasoconstriction, one way the body regulates heat and controls local blood flow.

By narrowing these vessels, the body limits the buildup associated with swelling and supports a sense of relief. At 58°F, this response is controlled rather than intense. A standard ice pack drops well below freezing, with little control over what reaches your skin — and pushes the body into a more protective response that's harder to regulate.

Your skin knows what's coming.
So does your body.

Your skin contains cold-sensitive receptors, including TRPM8 thermoreceptors, that help detect cooling and shape how it feels. At 58°F, these signals stay active, creating a clear and sustained cooling sensation.

With more extreme cold, sensation can begin to fade. As feeling dulls, it becomes harder to gauge what your skin is experiencing — and ice-based cooling can approach temperatures where irritation and damage become more likely.

Cooling you can feel.
Long enough to matter.

When skin is exposed to a controlled level of cold, activity beneath the surface begins to slow. Blood flow shifts, cellular activity becomes more measured, and the drivers of heat, swelling, and discomfort are less pronounced — a clearer signal the body can respond to over time.

Cooling isn't just about how cold something gets. It's about finding a temperature your body can stay with. Too cold feels abrupt and easy to overdo. Too mild may not create a meaningful response.

For many women, that range can shift — sensitivity to temperature isn't fixed, and it changes across life stages. SkinSafe™ 58°F is designed to sit right where your body can work with it.

A cooling temperature, calibrated with your physiology in mind.
