SKINSAFE™ 58°F — THE SCIENCE STORY
Skin safe. Science deep.
Most cold therapy has been built around extremes. Research increasingly points to a more effective range. Moderate cooling between 50–59°F.
Cold therapy is clinically backed, but wasn’t built with women in mind.
Women can experience cold differently. Hormonal changes may influence skin blood flow, vascular response, and thermal perception across life stages. It is a level of biological nuance not often reflected in how cooling products are designed.
SkinSafe™ 58°F was designed with that nuance in mind.
01 CIRCULATION
Your circulation feels it first.
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.
SkinSafe™ 58°F delivers cooling your body can settle into.
Your skin knows what's coming. So does your body.
Vasoconstriction: Your bodies smart response to temperature.
58° delivers a controlled cooling response.
Blood vessels near the skin’s surface adjust to help regulate temperature and reduce excess fluid. SkinSafe™ 58°F narrows blood vessels just enough to reduce heat and fluid — without going too far.
-
Vessels dilate to
release heat.- Vessels are dilated
More blood flow to the surface - More heat + fluid at the surface
May contribute to warmth, redness & swelling - Body is working to cool down
Heat is released outward
- Vessels are dilated
-
Gentle vasoconstriction
(controlled response)- Vessels gently narrow
Reduced blood flow to the surface - Less heat + fluid at the surface
Helps limit inflammation and visible swelling - Controlled, effective response
Cooling signal recognized without overwhelming the body
- Vessels gently narrow
-
Strong vasoconstriction
(over-response)- Vessels strongly constrict
Minimal blood flow to the surface - Significantly less heat + fluid
May reduce sensation and increase risk of tissue stress - Over-response
Cooling is too intense, can overwhelm or stress the body
- Vessels strongly constrict
02 Duration
Cooling you can feel.
Long enough to matter.
SkinSafe™ 58°F keeps the cooling present and perceptible.

58° Opal Cool
Cooling that lasts.
Your skin contains cold-sensitive receptors, including TRPM8 thermoreceptors, that help detect cooling and shape how it feels. These receptors respond to moderate cold and play a role in how the body interprets temperature and discomfort.
At 58°F, these signals remain active, creating a clear and sustained cooling sensation.
Freezing
Cold you can’t feel doesn’t last.
With more extreme cold, sensation can begin to fade. As feeling dulls, it becomes harder to gauge what your skin is experiencing. Ice-based cooling can approach near-freezing temperatures, where skin irritation and damage become more likely.
03 Sensation
What is happening beneath your skin.
Cooling does more than create a surface sensation. When the 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.
This is why cooling is often used to help manage temporary warmth, visible swelling, and post-activity discomfort.
The difference is how that cooling is delivered. A brief drop into extreme cold can be difficult for the body to regulate. More controlled cooling provides a clearer signal the body can respond to over time.
58°F is designed to maintain that level of control.
Your body responds best to a temperature that behaves.
What Cooling Does – Above & Beneath
Different temperatures. Different response times. Different results.
04 Precision is Personal
Cooling is not just about how cold something gets. It is about finding a temperature your body can stay with.
A cooling temperature, calibrated with your physiology in mind.
Too cold can feel abrupt, difficult to maintain, and easy to overdo. Too mild may not create a meaningful response.
In-between is a range where the body recognizes the signal, responds to it, and remains comfortable over time. Research increasingly points to this moderate range, roughly 50–59°F, as a zone where cooling can be both effective and tolerable.
For many women, that range can shift. Sensitivity to temperature is not fixed. It changes across life stages, influencing how cooling feels and how long it remains effective.
SkinSafe™ 58°F is designed to sit within that range.
Not too cold. Not too light. Right where your body can work with it.

Scientific References
Cold therapy is clinically backed and widely used to help manage pain, swelling, and tissue response. Research shows that cooling within moderate temperature ranges can be detected by the body, influence circulation, and remain tolerable over time.
Clinical and experimental research increasingly reflects a focus on moderate cooling, typically between 10–15°C (50–59°F), where temperature, duration, and consistency all contribute to the overall effect
SkinSafe™ 58°F was designed to sit within this range, where the body can sense, respond to, and stay with cooling.
Much of the earlier research focused on ice and near-freezing temperatures. More recent work reflects a broader understanding of how the body responds across a spectrum of cooling conditions.
